Hi thanks, but what sanitizer option should I set it to? -----Original Message----- From: Bossers, Alex [mailto:Alex.Bossers@wur.nl] Sent: Thursday, August 04, 2011 3:11 PM To: KOH Jia Yu Jayce Cc: 'galaxy-dev@lists.bx.psu.edu' Subject: RE: filter If I understand it correctly; You have to check the sanitize option for your tool. The pipe (among others) is usually by default sanitised into X.

After I used <sanitizer sanitize="False"/> the problem was solved. Is the error intentional and has consequences that we might have missed? Or is it a bug?
