## About

`miasort` is a Python Library for multiplex chromatin interaction analysis by efficiently sorting chromatin complexes.

To start using `miasort`, you need to install `bedtools`. To do so, follow instructions on https://bedtools.readthedocs.io/en/latest/content/installation.html#. One of the options is:

```Shell
$ mamba install -c conda-forge bedtools
```

After doing so, you can simply install our library:

```Shell
$ pip install miasort
```

## Documentation
### 1. `abc_sort()`

**Purpose**:
Sorts three regions and generates plots or histograms as needed.

**Parameters**:
- `path1` (str): Path to the first input file.
- `path2` (str): Path to the second input file.
- `graphs` (str): Graph configuration for sorting. There are in total 6 schemes: `AtoC`, `CtoA`, `AandC`, `Bcentered`, `BtoA` and `BtoC`. If you want all these 6 schemes, set this parameter as `AtoC;CtoA;AandC;Bcentered;BtoA;BtoC` (seperated by semicolons).
- `out_dir` (str, optional): Output directory for the results. Default is `'/'`.
- `plot` (bool, optional): Whether to generate plots. Default is `True`.
- `histogram` (bool, optional): Whether to generate histograms. Default is `False`.
- `anchor_option` (str, optional): Anchor options for sorting: `yes_complete` (drawing complex anchors), `yes_top` (drawing anchors on top of the plot), and `no` (do not draw anchors). Default is `'no'`.
- `colors` (str, optional): Colors for the anchors, fragments and lines on the plot respectively. Each item should be separated by a semicolon. Default is `'red;green;#525252'`.
- `num_frag_min` (int, optional): Minimum number of fragments required in one complex. Otherwise, we will not consider the complex. Default is `2`.
- `num_frag_max` (int, optional): Maximum number of fragments required in one complex. Otherwise, we will not consider the complex. Default is `1000`.
- `extension` (str, optional): Extension option for fragment drawing. It can be either `natural` (accurately represent each fragment's length) or an integer (each fragment's length will be set to this integer when the program outputs the plots). Default is `'6000'`.
- `frag_height` (float, optional): Fragment height for plots. Default is `0.6`.
- `line_width` (float, optional): Line width for plots. Default is `2.0`.
- `plot_width` (int, optional): Width of the plots. Default is `50`.
- `subplots_margins` (tuple of three elements, optional): Margins for subplots: `top`, `bottom` and `hspace` respectively. Learn more about these three metrics in [`matplotlib.pyplot.subplots_adjust`](https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.subplots_adjust.html). Default is `(0.9, 0.05, 0.9)`.

**Usage**:
```Python
import miasort

miasort.abc_sort("./data/test_input.region",
                 "./data/test_input.domains",
                 "AtoC;CtoA;AandC;Bcentered;BtoA;BtoC",
                 out_dir="./test_folder_syn_6000",
                 anchor_option="yes_complete")
```

The same code is in `tests/test_abc_sort.py`. To run the code, you can use this commandxx`:

```Shell
$ ./tests/test_abc_sort.py
```

**Results**:
This code will produce two plots:

(1)
![image](./imgs/test_input_cr1_M-1_jets_minfrag_2_maxfrag_1000_frag6000bp.png)
(2)
![image](./imgs/test_input_cr1_M-1_stripes_minfrag_2_maxfrag_1000_frag6000bp.png)

This code will also generate a CSV file:
