Despite notable efforts in the development of user-friendly softwares
that integrate state-of-the-art solutions to perform single cell
analysis, very few are designed for time-lapse data and even less for
multimodal problems where cells populations are mixed and can only be
separated through the use of multimodal information. Few software
solutions provide, to our knowledge, the extraction of response
functions from single cell events such as the dynamic survival of a
population directly in the GUI, as coding skills are usually required to
do so. We want to study complex data which is often multimodal time
lapse microscopy images of interacting cell populations, without loss of
generality. With a high need for an easy-to-use,
no-coding-skill-required software adapted to images and intended for
biologists, we introduce **Celldetective**, an open-source python-based
software with the following highlight features:

-   **Comprehensive single-cell image analysis** : Celldetective ships
    segmentation, tracking, and measurement modules, as well as event
    detection from single-cell signals, for up to two populations of
    interest.
-   **Integration of state-of-the-art solutions** : Celldetective
    harnesses state-of-the-art segmentation techniques (StarDist[^1],
    Cellpose[^2] ,[^3]) and tracking algorithm (bTrack[^4]), as well as
    the napari viewer[^5] where applicable. These algorithms are
    interfaced to be well integrated and accessible for the target
    audience, in the context of complex biological applications.
-   **A framework for event description and annotations** : we propose a
    broad and intuitive framework to annotate and automate the detection
    of events from single-cell signals through Deep Learning signal
    classification and regression. The event formulation is directly
    exploited to define population survival responses.
-   **A neighborhood scheme to study cell-cell interactions** : we
    introduce a neighborhood scheme to relate the spatio-temporal
    distribution and measurements of two cell populations, allowing the
    study of how cell-cell interactions affect single-cell and
    population responses.
-   **Deep Learning customization in GUI** : Celldetective facilitates
    the specialization of Deep Learning models or the creation of new
    ones adapted to user data, by facilitating the creation of training
    sets and the training of such models, without having to write a
    single line of code.
-   **In-software analysis** : Celldetective ships visualization tools
    to collapse single-cell signals with respect to an event, build
    survival curves, compare measurement distributions across biological
    conditions.
-   **A library of segmentation and signal models**: we created specific
    models to investigate a co-culture of MCF-7 cells and primary NK
    cells, that are available directly is the software with a large
    collection of generalist models developed by the StarDist and
    Cellpose teams, which are a perfect starting point to segment single
    cells in a new biological system.
-   **Accessible and open source** : Celldetective does not require any
    coding skills. The software, its models and datasets are made fully
    open source to encourage transparency and reproducibility.

# System requirements

## Hardware requirements

The software was tested on several machines, including:

-   An Intel(R) Core(TM) i9-10850K CPU @ 3.60GHz, with a single NVIDIA
    GeForce RTX 3070 (8 Gb of memory) and 16 Gb of memory
-   An Intel(R) Core(TM) i7-9750H CPU @ 2.60 GHz, with 16 Gb of memory

In GPU mode, succesive segmentation and DL signal analysis could be
performed without saturating the GPU memory thanks to the subprocess
formulation for the different modules. The GPU can be disabled in the
startup window. The software does not require a GPU (but model inference
will be longer). A typical analysis of a single movie with a GPU takes
between 5 to 15 minutes. Depending on the number of cells and frames on
the images, this computation time can increase to the order of half an
hour on a CPU.

The memory must be sufficient to load a movie stack at once in order to
visualize it in napari. Otherwise, processing is performed frame by
frame, therefore the memory required is extremely low.

## Software requirements

The software was developed simulateously on Ubuntu 20.04 and Windows 11.
It was tested on MacOS, but Tensorflow installation can rquire extra
steps.

-   Linux: Ubuntu 20.04.6 LTS (Focal Fossa) (not tested on ulterior
    versions)
-   Windows: Windows 11 Home 23H2

To use the software, you must install python, *e.g.* through
[Anaconda](https://www.anaconda.com/download). We developed and tested
the software in Python 3.9.18.

# Installation

## Stable release

Celldetective can be installed with `pip`:

``` bash
pip install celldetective
```

We recommend that you create an environment to use Celldetective, *e.g.*
with `conda`:

``` bash
conda create -n celldetective python=3.9.18 pyqt
conda activate celldetective
pip install celldetective
```

Need an update? Simply type the following in the terminal (in your
environment):

``` bash
pip install --upgrade celldetective
```

## Development version

### From GitHub

If you want to run the latest development version, you can clone the
repository to your local machine and install Celldetective in
"development" mode. This means that any changes to the cloned repository
will be immediately available in the python environment:

``` bash
# creates "celldetective" folder
git clone git://github.com/remyeltorro/celldetective.git
cd celldetective

# install the celldetective package in editable/development mode
pip install -r requirements.txt
pip install -e .
```

To run the latest development version without cloning the repository,
you can also use this line:

``` bash
pip install git+https//github.com/remyeltorro/celldetective.git
```

### From a zip file

You can also download the repository as a compressed file. Unzip the
file and open a terminal at the root of the folder (same level as the
file requirements.txt). We recommend that you create a python
environment as Celldetective relies on many packages that may interfere
with package requirements for other projects. Run the following lines to
create an environment named \"celldetective\":

``` bash
conda create -n celldetective python=3.9.18 pyqt
conda activate celldetective
pip install -r requirements.txt
pip install .
```

The installation of the dependencies will take a few minutes (up to half
an hour if the network is bad). The Celldetective package itself is
light and installs in a few seconds.

Before launching the software, move to a different directory as running
the package locally can create some bugs when locating the models.

# Quick start

You can launch the GUI by 1) opening a terminal and 2) typing the
following:

``` bash
python -m celldetective
```
