Dear All, 

I am currently analyzing large data set and to speed up things I am going to use cluster. 

I am working with DiffBind packadge and I will create a single GRanges object that will be used for dba.counts function to create few smaller binding matrixes, than combine them in one dba object (as they all have exectly the same ranges) and perform differential binding analysis .  However, I am not sure how to join few separate DBA objects into the one?

Kind Regrdas

You can use dba.peakset() to add all the peaks from one DBA object to another. If you want to add the peaks from myDBA2 to myDBA1, the call is:

> myDBA3 <- dba.peakset(myDBA1,peaks=myDBA2)

Cheers-

Rory
