Hello, I'm trying to run the MEDIPS package with the following script (loop over each chromosomes, compare each conditions ) everything works fine for the chr1 but at some point, the script raises an error for the chr2. (see below). Does anyone know what I've done wrong here ? Thank you Pierre (...) Preprocessing MEDIPS SET 6 in MSet2... Calculating calibration curve... Performing linear regression...

Hi Pierre, as you are looping over the chromosomes and your code works for chr1 and fails for chr2, my first guess would be that there are no regions for chr2. Can you check for that?
