## Acknowledgements
This project was based on the work by @Adoni5 and his repository [pyryotype](https://github.com/Adoni5/pyryotype). It was made to provide similar functionality to what is being offered by [KaryoploteR](https://bioconductor.org/packages/release/bioc/html/karyoploteR.html) package, but in a more pythonic style, using Matplotlib as the basis, and giving the user full liberty to plot anything they want. 

## Installation

```console
    pip install karyopyploter
```

## Example usage

```python
from karyopyploter import (
    GENOME,
    plot_ideogram,
    make_ideogram_grid,
    make_genome_grid,
    annotate_ideogram,
    add_ideogram_coordinates,
    reset_coordinates,
    zoom,
)
from matplotlib import pyplot as plt
from itertools import chain
from pathlib import Path

OUT_DIR = Path(__file__).parent.parent / "example_outputs" / "readme_example"
OUT_DIR.mkdir(parents=True, exist_ok=True)
genome = GENOME.CHM13
fig, axes = plt.subplots(
        ncols=1,
        nrows=22,
        figsize=(11, 11),
        facecolor="white",
    )
for ax, contig_name in zip(axes, [f"chr{i}" for i in chain(range(1, 23), "XY")]):
        chromosome = contig_name
        plot_ideogram(ax, target=chromosome, genome=genome, label=contig_name)
# similar to:
fig = plt.figure(figsize=(11, 11), facecolor="white")
fig, _, ideogram_axes = make_ideogram_grid(
    target=[f"chr{contig_name}" for contig_name in chain(range(1, 23), "XY")],
    num_subplots=0,
    genome=genome,
    fig=fig,
)
fig.savefig(TEST_DIR / "ideogram_grid1.png", dpi=300)
```
Will output:
![Example ideogram grid 1](https://raw.githubusercontent.com/vaslem/karyopyploter/main/example_outputs/readme_example/ideogram_grid1.png?raw=true)
```python
# and with a subplots grid
fig, ax, ideogram_axes = make_ideogram_grid(
        subplot_width=15,
        grid_params=dict(hspace=1),
        ideogram_factor=0.3,
        target=[f"chr{contig_name}" for contig_name in chain(range(1, 5))],
        num_subplots=1,
        genome=genome,
    )
fig.savefig(TEST_DIR / "ideogram_grid2.png", dpi=300)
```
Will output:
![Example ideogram grid 2](https://raw.githubusercontent.com/vaslem/karyopyploter/main/example_outputs/readme_example/ideogram_grid2.png?raw=true)
```python
# and with some regions annotated
regions = {'chr1':[(1000000,2000000, "red")], 'chr2':[(3000000, 4000000, 'blue')], 'chr3':[(5000000,6000000, (0,1,0)), (7000000,8000000, (1,0,0))]}
for chr in regions:
        annotate_ideogram(ideogram_axes[chr], regions=regions[chr], genome=genome)
fig.savefig(TEST_DIR / "ideogram_grid3.png", dpi=300)
```
Will output:
![Example ideogram grid 3](https://raw.githubusercontent.com/vaslem/karyopyploter/main/example_outputs/readme_example/ideogram_grid3.png?raw=true)
```python
# maybe we want to zoom in on specific regions
zoom_regions = {'chr1': (500000, 2500000), 'chr4': (3000000, 4000000)}
    for chr in zoom_regions:
        zoom(ideogram_axes[chr], start=zoom_regions[chr][0], stop=zoom_regions[chr][1])
fig.savefig(OUT_DIR / "ideogram_grid4.png", dpi=300)
```
Will output:
![Example ideogram grid 4](https://raw.githubusercontent.com/vaslem/karyopyploter/main/example_outputs/readme_example/ideogram_grid4.png?raw=true)
```
# or we want to show coordinates
for chr in zoom_regions:
    add_ideogram_coordinates(ideogram_axes[chr])
    reset_coordinates(ax[chr], ideogram_axes[chr])
fig.savefig(TEST_DIR / "ideogram_grid5.png", dpi=300)
```
Will output:
![Example ideogram grid 5](https://raw.githubusercontent.com/vaslem/karyopyploter/main/example_outputs/readme_example/ideogram_grid5.png?raw=true)

## TODOs
- Investigate the creation of circos plots, by polar transformation.
- Provide more detailed documentation, as some features are not described
