Bodged using string functions :-) set $data = ''.join([line for line in ($seq_source_type.seq_paste.split()) if line[0] != ">"]) Removes the fasta header line and any white-space so I can pipe sequence directly to blastn. Means users can quickly paste in a bit of sequence for blasting without first having to upload the data to their history. --Russell -- From: galaxy-dev-bounces@lists.bx.psu.edu [mailto:galaxy-dev-bounces@lists.bx.psu.edu] On Behalf Of Ross Sent: Wednesday, 13 February 2013 1:34 p.m. To: galaxy-dev@lists.bx.psu.edu Subject: [galaxy-dev] Fwd: Custom Cheetah filters? Hi Russell, There may be a better way, but this works for me in the Toolfactory to create space and special character free names? <param name="foo" type="text" value="" label="Foo"> <sanitizer invalid_char=""> <valid initial="string.letters,string.digits"/> </sanitizer> </param> On Wed, Feb 13, 2013 at 11:22 AM, Smithies, Russell <Russell.Smithies@agresearch.co.nz<mailto:Russell.Smithies@agresearch.co.nz>> wrote: I want to add a filter to strip whitespace and newlines from a text input box so I can pipe the sanitized string to a command. Documentation is a bit sparse (and my Python a bit basic) so does anyone have an example? Perhaps there's a better way of doing it - regex maybe? Any ideas?
