Hello everyone As one of the output file of macs2 is in excel form which tells -log10(q-value) which is the FDR (False Discover Rate) I wan to ask whether the highest q-value is reliable or the lowest as every peak has its own -log10(q-value) In other words if -log10(q-value) is 10.08 of one peak is that mean that peak has high chance to be a false positive or its the other way around ?

Thanks in advance...

Hi chaudharyc61, I have a question for you about that values,

how did you get that p-value?

My excel file does not have any columns for the p-value and the columns are this

Thank you

190While peak calling did you change the default p-value ?
