Find splicing-led, functional changes of the proteome.
spada (Splicing-led Protein Alterations Discovered Agilely) is a tool to study the functional impact of alternative splicing changes in case-control studies. The alterations are represented as isoform switches i.e. the situation when cases are best represented by one isoform, while controls are best represented by a different one. Then, spada is able to predict which protein features are changing between both isoforms, and their impact on the protein-protein interaction network.
To start using spada, simply install it with
pip install spada
This package has two main functionalities:
- Calculating isoform switches from case-control transcript expression data:
spada switches --expression-control expression_ctrl.tsv \ --expression-case expression_case.tsv --minimum-expression 0.1
- Predicting the effects of splicing on the protein structure and the interactome of a set of switches:
spada function --switches switches.tsv
