Hi everyone, I am trying to understand the problem I have when trying to annotate the peaks of my ChIP-seq that I got after MACS. I am using "operate on genomic intervals" tool to join bed file after MACS and the reference genome in gff3 (Arabidopsis TAIR10) format (that galaxy automatically treats as bed), but I cannot process this step, because the info "All datasets must belong to same genomic build, this dataset is linked to build '?' " is showed. What does it mean? Does it mean the reference genome is somehow incompatibile with the MACS reads? I used the built in galaxy TAIR10 genome and for the annotation a separate file that I downloaded from TAIR, but there should not be any difference between them, should there? Please help!
