[BioC] unknown error in DiffBind package

[Roberta Sanfilippo [guest]]

Hello!
I am using the DiffBind package to search for differences in histone modifications of ChIPseq peak data, I created a .csv files using sorted.bam files as both bamReads and Bamcontrol and bed files as Peaks column. I  tried to count reads using the dba.count function and changing the value minOverlap from 0 to 4, but every time I obtained:

 Error in if (res[i] == -1) { : missing value where TRUE/FALSE needed

WOuld you help me please? 

thank you

Roberta
