Hi all, How do I fix the following error?? INPUT DATA DOES NOT CONTAIN - Sequence and chr_coord SCANN THE DATA USING AFE 9.5.3.1 Error in read.AgilentFE(targets, makePLOT = FALSE) : the script will stop now I have tried the fix that I have found in the archive, but it did not work. I'm noit sure if I did id right. Unfortunately, I only have version AFE7.5 files that don't have these columns. Any help would be much appreciated. Thanks Matthew [[alternative HTML version deleted]]
