Hi,
I came across your package through your biorxiv paper.
Can the function getClusterSpecificPvalue be used on binary matrices? I am working with bulk atac seq data and generating a binary matrix (n*p) with each cell = 1 a peak n exists for sample p else 0. I can't use counts because of other issues. I am trying to use the function getClusterSpecificPvalue on this matrix to identify peaks specific to my pre-defined clusters of samples.
- Are any distribution assumptions being violated if I use a binary matrix with this function ?
- I also assigned the background medians to be all 1 so that none of the sample get removed as well all of them get equal weightage. Do you see any issues with that ?
Thanks for your help !

Excellent - Thanks !
To follow up, the Poisson assumption will give higher power for binary entries than a method such as DESeq2 or other methods for RNA-seq or scRNA-seq differential expression that use a Negative Binomial model.
The question of how to determine cluster specific peaks using a binary matrix is interesting and is likely something that should be explored in more depth.
