How to subsample ATAC fragment file?

Question

[bioinfo]

Hello,

I have 5 single cell ATAC samples that I have started analyzing with SnapATAC2. My WT samples have about twice the amount of cells as my knock outs and that is why I would like to do the analysis with all the cells and then I would like to subsample the WT so they have similar cell numbers to the knock outs. How can I do that?

Thank you
