**Chromatogram File Utils**

For Sanger sequencing data visualizing, alignment, mutation calling, and trimming etc.

## Demo

![plot chromatogram with mutation](https://raw.githubusercontent.com/y9c/cfutils/master/data/plot.png)

> command to generate the demo above

```bash
cfutils mut --query ./data/B5-M13R_B07.ab1 --subject ./data/ref.fa --outdir ./data/ --plot
```

## How to use?

- You can have mutation detection and visualization in one step using the command line.

```bash
cfutils mut --help
```

- You can also integrate the result matplotlib figures and use it as a python module.

An example:

```python
import matplotlib.pyplot as plt
import numpy as np

from cfutils.parser import parse_abi
from cfutils.show import plot_chromatograph

seq = parse_abi("./data/B5-M13R_B07.ab1")
peaks = seq.annotations["peak positions"][100:131]

fig, axes = plt.subplots(2, 1, figsize=(12, 6), sharex=True)
plot_chromatograph(
    seq,
    region=(100, 130),
    ax=axes[0],
    show_bases=True,
    show_positions=True,
    color_map=dict(zip("ATGC", ["C0", "C2", "C1", "C4"])),
)
axes[1].bar(peaks, np.random.randn(len(peaks)), color="0.66")
plt.show()
```

## How to install?

### form pypi

_(use this way ONLY, if you don't know what's going on)_

```bash
pip install --user cfutils
```

### manipulate the source code

- clone from github

```bash
git clone git@github.com:y9c/cfutils.git
```

- install the dependence

```bash
make init
```

- do unittest

```bash
make test
```

## ChangeLog

- Reverse completement the chromatogram file. (Inspired by Snapgene)
- build as python package for pypi
- fix bug that highlighting wrong base
- replace blastn with buildin python aligner

## TODO

- [ ] call mutation by alignment and plot Chromatogram graphic
- [ ] add a doc
- [x] change xaxis by peak location
- [ ] fix bug that chromatogram switch pos after trim
- [x] wrap as a cli app
- [ ] return quality score in output
- [ ] fix issue that selected base is not in the middle
- [ ] fix plot_chromatograph rendering bug

- [ ] add projection feature to make align and assemble possible
