shiba2sashimi 0.1.4

A utility for creating sashimi plot from Shiba output

🐕 shiba2sashimi 🍣 (v0.1.4)

A utility to create Sashimi plots, a publication-quality visualization of RNA-seq data, from Shiba output. Greatly inspired by rmats2sashimiplot and MISO's original implementation.

Quick start

shiba2sashimi -e /path/to/Shiba/experiment_table.tsv \
-s /path/to/Shiba/output/ -o img/sashimi_example.png \
--id "SE@chr2@157561213-157561293@157560260-157561542"

How to install

pip

pip install shiba2sashimi

or

git clone https://github.com/Sika-Zheng-Lab/shiba2sashimi.git
cd shiba2sashimi
pip install .

conda

conda create -n shiba2sashimi python=3.9
conda activate shiba2sashimi
conda install -c bioconda shiba2sashimi

shiba2sashimi v0.1.4 - Create Sashimi plot from Shiba output

optional arguments:
  -h, --help            show this help message and exit
  -e EXPERIMENT, --experiment EXPERIMENT
                        Experiment table used for Shiba
  -s SHIBA, --shiba SHIBA
                        Shiba output directory
  -o OUTPUT, --output OUTPUT
                        Output file
  --id ID               Positional ID (pos_id) of the event to plot
  -c COORDINATE, --coordinate COORDINATE
                        Coordinates of the region to plot
  --samples SAMPLES     Samples to plot. e.g. sample1,sample2,sample3 Default: all samples in the experiment table
  --groups GROUPS       Groups to plot. e.g. group1,group2,group3 Default: all groups in the experiment table. Overrides --samples
  --colors COLORS       Colors for each group. e.g. red,orange,blue
  --extend_up EXTEND_UP
                        Extend the plot upstream. Only used when not providing coordinates. Default: 500
  --extend_down EXTEND_DOWN
                        Extend the plot downstream. Only used when not providing coordinates. Default: 500
  --smoothing_window_size SMOOTHING_WINDOW_SIZE
                        Window size for median filter to smooth coverage plot. Greater value gives smoother plot. Default: 21
  --font_family FONT_FAMILY
                        Font family for labels
  --dpi DPI             DPI of the output figure. Default: 300
  -v, --verbose         Increase verbosity
