Allow manual specification of genes to annotate in decoupler.pl.volcano()

[dnjst]

Description of feature

Hi, when making volcano plots for either talks or papers, it is common sometimes to use other methods (including literature curation, more complex than linear sorting) to specify which genes to annotate/mark on the volcano.

It would be great if there could be an argument in decoupler.pl.volcano() to pass an iterable of index values in the dataframe to annotate (e.g. force_annotate=["BRCA1","BRCA2"]), either in conjunction with top=5 argument, as well as to allow values of top=0 or top=None to only show manually selected genes.

I am currently using a customized volcano plotting code to do this, but it seems it would be a useful addition to decoupler!

Hi @dnjst,

Thanks for the suggestion! I've just pushed a new version (2.1.5) to main that supports this. You can install it from GitHub by running:

pip install git+https://github.com/scverse/decoupler.git@main
