### Mesmerize core backend
[**Installation**](https://github.com/nel-lab/mesmerize-core#installation) | [**Examples**](https://github.com/nel-lab/mesmerize-core#examples)

A batch management system for calcium imaging analysis using the CaImAn library. 
It contains `pandas.DataFrame` and `pandas.Series` extensions that interface with CaImAn for running the various algorithms and organizing input & output data.

This **replaces** the [Mesmerize legacy desktop application](https://github.com/kushalkolar/MESmerize).\
`mesmerize-core` is MUCH faster, more efficient, and offers many more features! For example there are simple extensions which you can just call to get the motion correction shifts, CNMF reconstructed movie, CNMF residuals, contours etc.

# Documentation

We recommend starting out with the demo notebook ```notebooks/mcorr_cnmf.ipynb```

Documentation is available at: https://mesmerize-core.readthedocs.io/ \
User guide: https://mesmerize-core.readthedocs.io/en/latest/user_guide.html

Please use the GitHub issue tracker for any issues. For smaller questions or discussion use gitter.

# Overview

# Visualization

For visualization we strongly recommend [`fastplotlib`](https://github.com/kushalkolar/fastplotlib), a very new but very fast plotting library. Here are some examples of `fastplotlib` visualizations using `mesmerize-core` outputs. You can create these interactive plots within jupyter notebooks, therefore they will also work on cloud computing intrastructure!

### View raw and motion corrected movie side by side:

### Contours from CNMF, good components shown here in cyan and bad components in magenta:

### Input movie, constructed movie `(A * C)`, residuals `(Y - A * C - b * f)`, and reconstructed background `(b * f)`:

As mentioned, fastplotlib is meant to be a fast plotting library which can handle **millions** of points. You can create highly complex and interactive plots to combine outputs from the CaImAn algorithms with other experimentally relevant analysis, such as behavioral data.

# Examples

**See the `notebooks` directory for detailed examples.**

Note that [`fastplotlib`](https://github.com/kushalkolar/fastplotlib) is required for the visualizations.

# Installation

## For users

The instructions below will install `mesmerize-core`.

For visualization install `fastplotlib` into the same environment as `mesmerize-core`:

```bash
pip install fastplotlib
```

You may need to install Vulkan drivers depending on your system, see the `fastplotlib` repo for more information: https://github.com/kushalkolar/fastplotlib#install-vulkan-drivers

### Conda

`mesmerize-core` is availabe as a conda package which also gives you CaImAn! These instructions will give you a working `mesmerize-core` along with `caiman` in the same environment.

**Important note: Sometimes conda or mamba will get stuck at a step, such as creating an environment or installing a package. I found that pressing `Enter` on your keyboard can sometimes help it continue when it pauses.**

1. Install `mamba` into your base environment. Skip this step if you have `mamba`. This step may take 10 minutes and display several messages like "Solving environment: failed with..." but it should eventually install `mamba`.

```bash
conda install -c conda-forge mamba

# if conda is behaving slow, this command can sometimes help
conda clean -a
```

2. To create a new environment and install `mesmerize-core` into it do this:

```bash
mamba create -n mescore -c conda-forge mesmerize-core
```

`caiman` is a dependency of `mesmerize-core` so it will automatically grab `caiman` too

If you already have an environment with `caiman`:

```bash
mamba install -n name-of-env-with-caiman mesmerize-core
```

3. Activate environment. You can only use `mesmerize-core` in the environment that it's installed into.

```bash
mamba activate mescore
```

4. Install `caimanmanager`

```bash
caimanmanager.py install
```

The `caimanmanager.py` step may cause issues, especially on Windows. Assuming your anaconda is in your user directory a workaround is to call it using the full path:

```bash
python C:\Users\your-username\anaconda3\envs\your-env-name\bin\caimanmanager.py install
```

If you continue to have issues with this step, please post an issue on the caiman github or gitter: https://github.com/flatironinstitute/CaImAn/issues 

5. Run `ipython` and verify that `mesmerize_core` is installed:

```bash
# run in ipython
import mesmerize_core
mesmerize_core.__version__
```

6. Install `fastplotlib` for visualization into the same environment (run this in the anaconda prompt, not ipython). You may also need to install Vulkan drivers depending on your system, see the `fastplotlib` repo for more information: https://github.com/kushalkolar/fastplotlib#install-vulkan-drivers

```bash
pip install fastplotlib
```

### python virtual environments
