I am using DiffBind Bio-conductor for differential binding analysis. I have four replicates of same experiment so the Condition column is same for all the replicates, while getting the contrast in R (i.e My_data <- dba.contrat(My_data, categories = DBA_CONDITION) ) I am getting warning :
Warning message: No contrasts added. Perhaps try more categories, or lower value for minMembers.
I tried changing minMemebers and also the categories but still the same error is coming. Please Help
