splicekit is a modular platform for splicing analysis from short-read RNA-seq datasets. The platform also integrates an JBrowse2 instance, pybio for genomic operations and scanRBP for RNA-protein binding studies. The whole analysis is self-contained (one single folder) and the platform is written in Python, in a modular way.
Check a short video presentation about splicekit (poster) at ECCB 2023 on Youtube:
The easiest way to install splicekit is to simply run:
$ pip install splicekit
Note that on some systems, pip is installing the executable scripts under ~/.local/bin
. However this folder is not in the PATH which will result in command not found
if you try to run $ splicekit
on the command line. To fix this, please execute:
export PATH="$PATH:~/.local/bin"
Another suggestion is to install inside a virtual environment (using virtualenv
).
Installing splicekit directly from the GitHub repository
pip install git+https://github.com/bedapub/splicekit.git@main
If you already have aligned reads in BAM files
All you need is samples.tab
(note that this is a TAB delimited file) and splicekit.config
in one folder (check datasets for examples).
You can easily download and prepare the reference genome (e.g. $ pybio genome homo_sapiens
).
Finally run $ splicekit process
(inside the folder with samples.tab
and splicekit.config
).
Easiest is to check datasets examples to see how the above files look like and also to check scripts if you need to map reads from FASTQ files with pybio
.
