Hi, Paolo, DiffBind uses quite a lot of memory for the dba.count step, because it loads the whole data file into memory. (In hindsight, not the best design choice...) Try running with parallelization turned off: > test=dba.count(test,bParallel=F) so that it only loads one file at a time, to reduce the memory footprint. For the upcoming release, we'll probably fix this, at the cost of somewhat slower counting. How much RAM does your machine have?
