I would like to compare H3K4me3 ChIP peaks of several samples at TSS. Therefore, I used "compute matrix" and then "plot profile" or "plot heatmap". The sample names in the plots are "file_0", "file_1", "file_2" etc. How do I know which sample is which one and how can I change the names? Are they ordered according to the number in my galaxy history?
Thanks for your help.
