Hello,
I tried DiffBind (v3.0.9) to find DE binding sites from ChIP-seq data. When I used "dba.normalize" with "background=TRUE". It ended up with this error:
DB = dba.normalize(DB, normalize=DBA_NORM_NATIVE, background=TRUE)
Generating background bins...
Error in .local(x, ...) :
cannot create 160 workers; 125 connections available in this session
sessionInfo( )
It seems that my server has 160 cpu cores, and BiocParallel or parallel embeded in DiffBind aquire all the cpu cores in running the task, while the R session only support up to 125 cores.
I'm woundering if you can provide any solution to this issue?
Thanks very much!
