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!

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
ftp://ftp.ensembl.org/pub/release-65/gtf/mus_musculus/.
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
