Few tumor cell

[sunshine1126]

Hello, Thank you for your software. When I used the plotHistogram function to identify tumor cells for scATAC-seq data, I found that only a small part of cells was identified as tumor cells which may be incorrect. There are too many normal cells！

plotHistogram=plotHistogram(l,suva_expr,clusters=2,zscoreThreshold=4)
normal= which(hi==1) ## 1354
tumor=which(hi!=1) ## 48
