## Requirements

Python 3.9+ is required.

We recommend [Anaconda](https://www.continuum.io/downloads/) which comes with a suite of packages useful for scientific data analysis. Step-by-step instructions for installing Anaconda can be found at: [Windows](https://docs.anaconda.com/anaconda/install/windows/), [macOS](https://docs.anaconda.com/anaconda/install/mac-os/), [Linux](https://docs.anaconda.com/anaconda/install/linux/)


## Installation

### Virtual Environment
To avoid potential dependency issues with other Python packages, we suggest creating a virtual environment for PySPEDAS; you can create a virtual environment in your terminal with:

```bash
python -m venv pyspedas
```

To enter your virtual environment, run the 'activate' script:

#### Windows

```bash
.\pyspedas\Scripts\activate
```

#### macOS and Linux

```bash
source pyspedas/bin/activate
```

#### Using Jupyter notebooks with your virtual environment

To get virtual environments working with Jupyter, in the virtual environment, type:

```bash
pip install ipykernel
python -m ipykernel install --user --name pyspedas --display-name "Python (pySPEDAS)"
```

(note: "pyspedas" is the name of your virtual environment)

Then once you open the notebook, go to "Kernel" then "Change kernel" and select the one named "Python (PySPEDAS)"

### Install
PySPEDAS supports Windows, macOS and Linux. To get started, install the `pyspedas` package using PyPI:

```bash
pip install pyspedas
```

### Upgrade

To upgrade to the latest version of PySPEDAS:

```bash
pip install pyspedas --upgrade
```


## Local Data Directories

The recommended way of setting your local data directory is to set the `SPEDAS_DATA_DIR` environment variable. `SPEDAS_DATA_DIR` acts as a root data directory for all missions, and will also be used by IDL (if you’re running a recent copy of the bleeding edge).

Mission specific data directories (e.g., `MMS_DATA_DIR` for MMS, `THM_DATA_DIR` for THEMIS) can also be set, and these will override `SPEDAS_DATA_DIR`

## Cloud Repositories

`SPEDAS_DATA_DIR` and mission specific data directories can also be the URI of a cloud repository (e.g., an S3 repository). If this data directory is set to an URI, files will be downloaded from the data server to the URI location. The data will then be streamed from the URI without needing to download the file locally. 

In order to successfully access the specified cloud repository, the user is required to correctly set up permissions to be able to read and write to that cloud repository on their own. Refer (here)[https://docs.aws.amazon.com/cli/v1/userguide/cli-configure-files.html] for how to prepare your AWS configuration and credentials.

## Usage

To get started, import pyspedas and pytplot:

```python
import pyspedas
from pytplot import tplot
```

You can load data into tplot variables by calling `pyspedas.mission.instrument()`, e.g.,

To load and plot 1 day of THEMIS FGM data for probe 'd':
```python
thm_fgm = pyspedas.themis.fgm(trange=['2015-10-16', '2015-10-17'], probe='d')

tplot(['thd_fgs_gse', 'thd_fgs_gsm'])
```

To load and plot 2 minutes of MMS burst mode FGM data:
```python
mms_fgm = pyspedas.mms.fgm(trange=['2015-10-16/13:05:30', '2015-10-16/13:07:30'], data_rate='brst')

tplot(['mms1_fgm_b_gse_brst_l2', 'mms1_fgm_b_gsm_brst_l2'])
```

Note: by default, PySPEDAS loads all data contained in CDFs found within the requested time range; this can potentially load data outside of your requested trange. To remove the data outside of your requested trange, set the `time_clip` keyword to `True`

To load and plot 6 hours of PSP SWEAP/SPAN-i data:
```python
spi_vars = pyspedas.psp.spi(trange=['2018-11-5', '2018-11-5/06:00'], time_clip=True)

tplot(['DENS', 'VEL', 'T_TENSOR', 'TEMP'])
```

To download 5 days of STEREO magnetometer data (but not load them into tplot variables):
```python
stereo_files = pyspedas.stereo.mag(trange=['2013-11-1', '2013-11-6'], downloadonly=True)
```

### Standard Options
- `trange`: two-element list specifying the time range of interest. This keyword accepts a wide range of formats
- `time_clip`: if set, clip the variables to the exact time range specified by the `trange` keyword
- `suffix`: string specifying a suffix to append to the loaded variables
- `varformat`: string specifying which CDF variables to load; accepts the wild cards * and ?
- `varnames`: string specifying which CDF variables to load (exact names)
- `get_support_data`: if set, load the support variables from the CDFs
- `downloadonly`: if set, download the files but do not load them into tplot
- `no_update`: if set, only load the data from the local cache
- `notplot`: if set, load the variables into dictionaries containing numpy arrays (instead of creating the tplot variables)
