Hi All, I got a bit disappointed when I failed in the following operation which seems to be simple. I uploaded mouse annotation/reference gene sets (GTF format) to Galaxy. The file is located at As far as I know, GTF file is tab delimited, thus I used "Filter and Sort" --"filter" With following condition:C1 == 19 . column 1 is where chromosomes are located. I want to pick up all lines which belong to chromosome19. However, I only got an empty file. I know this is not a bit issue to discuss here. But I still hope you can help me figure out what 's wrong. Thanks Jiwen

Hi Jiwen, The way the filter expression evaluates, you need to specify that you're matching on the string '19', and not the numerical value 19. Everything should work if you rerun with the filter condition: c1=='19' Thanks! Dannon
