## About

AlphaPeptDeep (`peptdeep` for short) aims to easily build new deep
learning models for shotgun proteomics studies. Transfer learning is
also easy to apply using AlphaPeptDeep.

It contains some built-in models such as retention time (RT), collision
cross section (CCS), and tandem mass spectrum (MS2) prediction for given
peptides. With these models, one can easily generate a predicted library
from fasta files.

For details, check out our
[publication](https://www.biorxiv.org/content/10.1101/2022.07.14.499992v1).

For documentation, see [GitHub
pages](https://mannlabs.github.io/alphapeptdeep/).

## License

AlphaPeptDeep was developed by the [Mann Labs at the Max Planck
Institute of Biochemistry](https://www.biochem.mpg.de/mann) and the
[University of
Copenhagen](https://www.cpr.ku.dk/research/proteomics/mann/) and is
freely available with an [Apache License](LICENSE.txt). External Python
packages (available in the [requirements](requirements) folder) have
their own licenses, which can be consulted on their respective websites.

------------------------------------------------------------------------

## Installation

AlphaPeptDeep can be installed and used on all major operating systems
(Windows, macOS and Linux).

There are three different types of installation possible:

- [**One-click GUI installer:**](#one-click-gui) Choose this
  installation if you only want the GUI and/or keep things as simple as
  possible.
- [**Pip installer:**](#pip) Choose this installation if you want to use
  peptdeep as a Python package in an existing Python (recommended Python
  3.8) environment (e.g. a Jupyter notebook). If needed, the GUI and CLI
  can be installed with pip as well.
- [**Developer installer:**](#developer) Choose this installation if you
  are familiar with CLI tools, [conda](https://docs.conda.io/en/latest/)
  and Python. This installation allows access to all available features
  of peptdeep and even allows to modify its source code directly.
  Generally, the developer version of peptdeep outperforms the
  precompiled versions which makes this the installation of choice for
  high-throughput experiments.

### One-click GUI

The GUI of peptdeep is a completely stand-alone tool that requires no
knowledge of Python or CLI tools. Click on one of the links below to
download the latest release for:

- [**Windows**](https://github.com/MannLabs/alphapeptdeep/releases/latest/download/peptdeep_gui_installer_windows.exe)
- [**macOS**](https://github.com/MannLabs/alphapeptdeep/releases/latest/download/peptdeep_gui_installer_macos.pkg)
- [**Linux**](https://github.com/MannLabs/alphapeptdeep/releases/latest/download/peptdeep_gui_installer_linux.deb)

Older releases remain available on the [release
page](https://github.com/MannLabs/alphapeptdeep/releases), but no
backwards compatibility is guaranteed.

Note that these installers do not have GPU supported.

### Pip

peptdeep can be installed in an existing Python 3.8 environment with a
single `bash` command. *This `bash` command can also be run directly
from within a Jupyter notebook by prepending it with a `!`*:

``` bash
pip install peptdeep
```

Installing peptdeep like this avoids conflicts when integrating it in
other tools, as this does not enforce strict versioning of dependancies.
However, if new versions of dependancies are released, they are not
guaranteed to be fully compatible with peptdeep. This should only occur
in rare cases where dependencies are not backwards compatible.

> **TODO** You can always force peptdeep to use dependancy versions
> which are known to be compatible with:
>
> ``` bash
> pip install "peptdeep[stable]"
> ```
>
> NOTE: You might need to run `pip install pip` before installing
> peptdeep like this. Also note the double quotes `"`.

For those who are really adventurous, it is also possible to directly
install any branch (e.g. `@development`) with any extras
(e.g. `#egg=peptdeep[stable,development-stable]`) from GitHub with e.g.

``` bash
pip install "git+https://github.com/MannLabs/alphapeptdeep.git@development#egg=peptdeep[stable,development-stable]"
```

### Use GPU

To enable GPU, GPU version of PyTorch is required, it can be installed
with:

``` bash
pip install torch --extra-index-url https://download.pytorch.org/whl/cu116
```

See [pytorch.org](https://pytorch.org/get-started/locally/) for details.

### Developer

peptdeep can also be installed in editable (i.e. developer) mode with a
few `bash` commands. This allows to fully customize the software and
even modify the source code to your specific needs. When an editable
Python package is installed, its source code is stored in a transparent
location of your choice. While optional, it is advised to first (create
and) navigate to e.g. a general software folder:

``` bash
mkdir ~/folder/where/to/install/software
cd ~/folder/where/to/install/software
```

***The following commands assume you do not perform any additional `cd`
commands anymore***.

Next, download the peptdeep repository from GitHub either directly or
with a `git` command. This creates a new peptdeep subfolder in your
current directory.

``` bash
git clone https://github.com/MannLabs/alphapeptdeep.git
```

For any Python package, it is highly recommended to use a separate
[conda virtual environment](https://docs.conda.io/en/latest/), as
otherwise *dependancy conflicts can occur with already existing
packages*.

``` bash
conda create --name peptdeep python=3.8 -y
conda activate peptdeep
```

Finally, peptdeep and all its [dependancies](requirements) need to be
installed. To take advantage of all features and allow development (with
the `-e` flag), this is best done by also installing the [development
dependencies](requirements/requirements_development.txt) instead of only
the [core dependencies](requirements/requirements.txt):

``` bash
pip install -e ".[development]"
```

By default this installs loose dependancies (no explicit versioning),
although it is also possible to use stable dependencies
(e.g. `pip install -e ".[stable,development-stable]"`).

***By using the editable flag `-e`, all modifications to the [peptdeep
source code folder](peptdeep) are directly reflected when running
peptdeep. Note that the peptdeep folder cannot be moved and/or renamed
if an editable version is installed. In case of confusion, you can
always retrieve the location of any Python module with e.g. the command
`import module` followed by `module.__file__`.***

------------------------------------------------------------------------

## Usage

There are three ways to use peptdeep:

- [**GUI**](#gui)
- [**CLI**](#cli)
- [**Python**](#python-and-jupyter-notebooks)

NOTE: The first time you use a fresh installation of peptdeep, it is
often quite slow because some functions might still need compilation on
your local operating system and architecture. Subsequent use should be a
lot faster.

### GUI

If the GUI was not installed through a one-click GUI installer, it can
be activate with the following `bash` command:

``` bash
peptdeep gui
```

This command will start a web server and automatically open the default
browser:
![](https://user-images.githubusercontent.com/4646029/189301730-ac1f92cc-0e9d-4ba3-be1d-07c4d66032cd.jpg)

There are several options in the GUI (left panel): \* Server: Start/stop
the task server, check tasks in the task queue \* Settings: Configure
common settings, load/save current settings \* Model: Configure DL
models for prediction or transfer learning \* Transfer: Refine the model
\* Library: Predict a library \* Rescore: Perform ML feature extraction
and Percolator

------------------------------------------------------------------------

### CLI

The CLI can be run with the following command (after activating the
`conda` environment with `conda activate peptdeep` or if an alias was
set to the peptdeep executable):

``` bash
peptdeep -h
```

It is possible to get help about each function and their (required)
parameters by using the `-h` flag. AlphaPeptDeep provides several
commands for CLI uses:

- [**export-settings**](#export-settings)
- [**library**](#library)
- [**transfer**](#transfer)
- [**rescore**](#rescore)
- [**install-models**](#install-models)
- [**gui**](#gui)

Run a command to check usages:

``` bash
peptdeep $command -h
```

For example:

``` bash
peptdeep library -h
```

#### export-settings

``` bash
peptdeep export-settings yaml_file
```

This command will export the default settings into the `yaml_file` as a
template, users can edit the yaml file to run other commands.

The common settings in the yaml file are:

    model_url: "https://github.com/MannLabs/alphapeptdeep/releases/download/pre-trained-models/pretrained_models.zip"

        verbose: True
        multiprocessing: True

The `model_mgr` section in the yaml defines the common settings for
MS2/RT/CCS prediction.

------------------------------------------------------------------------

#### library

``` bash
peptdeep library settings_yaml
```

This command will predict a spectral library for given settings_yaml
file (exported by [export-settings](#export-settings)). All the
essential settings are in the `library` section in the settings_yaml
file:

    library:
      input:
        infile_type: fasta
        infile_type_choices:
        - fasta
        - sequence_table
        - peptide_table
        - precursor_table
        infiles: 
        - xxx.fasta
        fasta:
          protease: '([KR])'
          protease_choices:
          - 'trypsin/P'
          - '([KR])'
          - 'trypsin'
          - '([KR](?=[^P]))'
          - 'lys-c'
          - 'K'
          - 'lys-n'
          - '\w(?=K)'
          - 'chymotrypsin'
          max_miss_cleave: 2
        fix_mods: 
        - Carbamidomethyl@C
        var_mods:
        - Acetyl@Protein N-term
        - Oxidation@M
        min_var_mod_num: 0
        max_var_mod_num: 2
        min_precursor_charge: 2
        max_precursor_charge: 4
        min_peptide_len: 7
        max_peptide_len: 35
        min_precursor_mz: 200.0
        max_precursor_mz: 2000.0
        decoy: pseudo_reverse
        decoy_choices:
        - pseudo_reverse
        - diann
        - None
        max_frag_charge: 2
        frag_types:
        - b
        - y
      output_folder: "{PEPTDEEP_HOME}/spec_libs"
      output_tsv:
        enabled: False
        min_fragment_mz: 200
        max_fragment_mz: 2000
        min_relative_intensity: 0.01
        keep_higest_k_peaks: 12
        translate_batch_size: 1000000
        translate_mod_to_unimod_id: False

peptdeep will load sequence data based on `library:input:infile_type`
and `library:input:infiles` for library prediction.
`library:input:infiles` contains the list of files with
`library:input:infile_type` defined in
`library:input:infile_type_choices`:

- fasta: Protein fasta files.
- sequence_table: Tab/comma-separated txt/tsv/csv (text) files which
  contain the column `sequence`
- peptide_table: Tab/comma-separated txt/tsv/csv (text) files which
  contain the columns `sequence`, `mods`, and `mod_sites`. peptdeep will
  not add modifications for this file type.
- precursor_table: Tab/comma-separated txt/tsv/csv (text) files which
  contain the columns `sequence`, `mods`, `mod_sites`, and `charge`.
  peptdeep will not add modifications and charge states for this file
  type. \>Columns of `proteins` and `genes` are optional for these
  txt/tsv/csv files.

peptdeep supports multiple files for library prediction, for example (in
the yaml file):

    library:
      input:
        ...
        infile_type: fasta
        iifiles:
        - /path/to/fasta/human.fasta
        - /path/to/fasta/yeast.fasta
        ...

The library in HDF5 (.hdf) format will be saved into
`library:output_folder`. If `library:output_tsv:enabled` is True, a TSV
spectral library that can be processed by DIA-NN and Spectronaut will
also be saved into `library:output_folder`.

------------------------------------------------------------------------

#### transfer

``` bash
peptdeep transfer settings_yaml
```

This command will apply transfer learning to refine RT/CCS/MS2 models
based on `model_mgr:transfer:psm_files` and
`model_mgr:transfer:psm_type`. All yaml settings (exported by
[export-settings](#export-settings)) related to this command are:

    model_mgr:
      transfer:
        model_output_folder: "{PEPTDEEP_HOME}/refined_models"
        epoch_ms2: 20
        warmup_epoch_ms2: 10
        batch_size_ms2: 512
        lr_ms2: 0.0001
        epoch_rt_ccs: 40
        warmup_epoch_rt_ccs: 10
        batch_size_rt_ccs: 1024
        lr_rt_ccs: 0.0001
        verbose: False
        grid_nce_search: True
        grid_nce_first: 15.0
        grid_nce_last: 45.0
        grid_nce_step: 3.0
        grid_instrument: ['Lumos']
        psm_type: alphapept
        psm_type_choices:
          - alphapept
          - pfind
          - maxquant
          - diann
          - speclib_tsv
        psm_files: []
        ms_file_type: alphapept_hdf
        ms_file_type_choices:
          - alphapept_hdf
          - thermo_raw
          - mgf
          - mzml
        ms_files: []
        psm_num_to_train_ms2: 100000000
        psm_num_per_mod_to_train_ms2: 50
        psm_num_to_train_rt_ccs: 100000000
        psm_num_per_mod_to_train_rt_ccs: 50
        top_n_mods_to_train: 10

For DDA data, peptdeep can also extract MS2 intensities from the
spectrum files from `model_mgr:transfer:ms_files` and
`model_mgr:transfer:ms_file_type` for all PSMs. This will enable the
transfer learning of the MS2 model.

For DIA data, only RT and CCS (if timsTOF) models will be refined.

For example of the settings yaml:

    model_mgr:
      transfer:
        ...
        psm_type: pfind
        psm_files:
        - /path/to/pFind.spectra
        - /path/to/other/pFind.spectra

        ms_file_type: thermo_raw
        ms_files:
        - /path/to/raw1.raw
        - /path/to/raw2.raw
        ...

The refined models will be saved in
`model_mgr:transfer:model_output_folder`. After transfer learning, users
can apply the new models by replacing `model_mgr:external_ms2_model`,
`model_mgr:external_rt_model` and `model_mgr:external_ccs_model` with
the saved `ms2.pth`, `rt.pth` and `ccs.pth` in
`model_mgr:transfer:model_output_folder`. This is useful to perform
sample-specific library prediction.

------------------------------------------------------------------------

#### rescore

This command will apply Percolator to rescore DDA PSMs in
`percolator:input_files:psm_files` and
`percolator:input_files:psm_type`. All yaml settings (exported by
[export-settings](#export-settings)) related to this command are:

    percolator:
      require_model_tuning: True
      raw_num_to_tune: 8

      require_raw_specific_tuning: True
      raw_specific_ms2_tuning: False
      psm_num_per_raw_to_tune: 200
      epoch_per_raw_to_tune: 5

      multiprocessing: True

      top_k_frags_to_calc_spc: 10
      calibrate_frag_mass_error: False
      max_perc_train_sample: 1000000
      min_perc_train_sample: 100

        - sequence
      use_fdr_for_each_raw: False
      frag_types: ['b_z1','b_z2','y_z1','y_z2']
      input_files:
        psm_type: alphapept
        psm_type_choices:
          - alphapept
          - pfind
          - maxquant
        psm_files: []

          - mgf
          - mzml
        ms_files: []
        other_score_column_mapping:
          alphapept: {}
          pfind: 
            raw_score: Raw_Score
          msfragger:
            hyperscore: hyperscore
            nextscore: nextscore
          maxquant: {}
      output_folder: "{PEPTDEEP_HOME}/rescore"

Transfer learning will be applied if `percolator:require_model_tuning`
is True.

The corresponding MS files (`percolator:input_files:ms_files` and
`percolator:input_files:ms_file_type`) must be provided to extract
experimental fragment intensities.

------------------------------------------------------------------------

#### install-models

``` bash
peptdeep install-models --model-file url_or_local_model_zip --overwrite True
```

Running peptdeep for the first time, it will download and install models
from [models on
github](https://github.com/MannLabs/alphapeptdeep/releases/download/pre-trained-models/pretrained_models.zip)
defined in ‘model_url’ in the default yaml settings. This command will
update `pretrained_models.zip` from
`--model-file url_or_local_model_zip`.

It is also possible to use other models instead of the pretrained_models
by providing `model_mgr:external_ms2_model`,
`model_mgr:external_rt_model` and `model_mgr:external_ccs_model`.

------------------------------------------------------------------------

### Python and Jupyter notebooks

Using peptdeep from Python script or notebook provides the most flexible
way to access all features in peptdeep.

We will introduce several usages of peptdeep via Python notebook:

- [**global_settings**](#global_settings)
- [**Pipeline APIs**](#pipeline-apis)
- [**ModelManager**](#modelmanager)
- [**Library Prediction**](#library-prediction)
- [**DDA Rescoring**](#dda-rescoring)
- [**HLA Peptide Prediction**](#hla-peptide-prediction)

------------------------------------------------------------------------

#### global_settings

Most of the default parameters and attributes peptdeep functions and
classes are controlled by `peptdeep.settings.global_settings` which is a
`dict`.

    from peptdeep.settings import global_settings

The default values of `global_settings` is defined in
[default_settings.yaml](https://github.com/MannLabs/alphapeptdeep/blob/main/peptdeep/constants/default_settings.yaml).

#### Pipeline APIs

Pipeline APIs provides the same functionalities with [CLI](#cli),
including [library prediction](#library), [transfer
learning](#transfer), and [rescoring](#rescore).

``` python
from peptdeep.pipeline_api import (
    generate_library,
    transfer_learn, 
    rescore,
)
```

All these functionalities take a `settings_dict` as the inputs, the dict
structure is the same as the settings yaml file. See the documatation of
[`generate_library`](https://MannLabs.github.io/alphapeptdeep/pipeline_api.html#generate_library),
[`transfer_learn`](https://MannLabs.github.io/alphapeptdeep/pipeline_api.html#transfer_learn),
and
[`rescore`](https://MannLabs.github.io/alphapeptdeep/pipeline_api.html#rescore).

#### ModelManager

``` python
from peptdeep.pretrained_models import ModelManager
```

[`ModelManager`](https://MannLabs.github.io/alphapeptdeep/pretrained_models.html#modelmanager)
class is the main entry to access MS2/RT/CCS models. It provides
functionalities to train/refine the models and then use the new models
to predict the data.

Check out
[tutorial_model_manager.ipynb](https://github.com/MannLabs/alphapeptdeep/blob/main/nbs/tutorial_model_manager.ipynb)
for details.

#### Library Prediction

``` python
from peptdeep.protein.fasta import PredictFastaSpecLib
```

[`PredictFastaSpecLib`](https://MannLabs.github.io/alphapeptdeep/protein/fasta.html#predictfastaspeclib)
class provides functionalities to deal with fasta files or protein
sequences and spectral libraries.

Check out
[tutorial_speclib_from_fasta.ipynb](https://github.com/MannLabs/alphapeptdeep/blob/main/nbs/tutorial_speclib_from_fasta.ipynb)
for details.

#### DDA Rescoring

``` python
from peptdeep.rescore.percolator import Percolator
```

[`Percolator`](https://MannLabs.github.io/alphapeptdeep/rescore/percolator.html#percolator)
class provides functionalities to rescore DDA PSMs search by `pFind` and
`AlphaPept`, (and `MaxQuant` if output FDR=100%), …

Check out
[test_percolator.ipynb](https://github.com/MannLabs/alphapeptdeep/blob/main/nbs_tests/test_percolator.ipynb)
for details.

#### HLA Peptide Prediction

``` python
from peptdeep.model.model_interface import ModelInterface
import peptdeep.model.generic_property_prediction # model shop
```

Building new DL models for peptide property prediction is one of the key
features of AlphaPeptDeep. The key functionalities are
[`ModelInterface`](https://MannLabs.github.io/alphapeptdeep/model/model_interface.html#modelinterface)
and the pre-designed models and model interfaces in the model shop
(module `peptdeep.model.generic_property_prediction`).

For example, we can built a HLA classifier that distinguishes HLA
peptides from non-HLA peptides, see
[HLA_peptide_prediction.ipynb](https://github.com/MannLabs/alphapeptdeep/blob/main/nbs/HLA_peptide_prediction.ipynb)
for details.
