Hi everyone,
I tried to use MACS for a fly chipseq data. I used genome size 1.2X108, and kept other default parameters. But the program gave an error message 'more than XXXXX tags mapped to position XXXXXX on chromosome 3L'. This happened to one of my replicates. The other replicate ran perfectly. Does anyone know what causes this error? How do I deal with it? Thank you so much!
