Hi,
I read on Readme for MACS that: "For the experiment with several replicates, it is recommended to concatenate several ChIP-seq treatment files into a single file".
Now, I have illumina ChipSeq data: two files for IP samples and two files for Control samples. Is It right to use Concatenate datasets (text manipulation) and then use MACS for the peaks calling?
Thank you so much.
