Hi all, Thanks for the answers, I do see the Trim sequence tool on the galaxy test website, but when I run the tool on a small fasta file, it seems to crash constantly. Is that because it does not recognize my fasta file?? Furthermore, I am not a programmer (have to become one, I guess) so I would like to try the FastX program. I will try that too.

Thanks Chris:
This tool is already in Galaxy on the test site (http://test.g2.bx.psu.edu ) under "NGS: QC and manipulation" section.

Hi Thomas,
Unless you can code it yourself (it's a fairly trivial thing to do), I would recommend the Fastx toolkit which includes a tool for this (amongst many other things) http://hannonlab.cshl.edu/fastx_toolkit/
Cheers,
Chris

Hi All, I have a little how to do question and was hoping somebody knows the answer?
I have a metagenomic data set with reads of lengths between 100 and 1000 bp. Now I want to create a dataset from my original dataset, with sequences of exact 200bp. I know I can use the filter tool to extract all reads longer than 199bp from the original data set. But then I want to cut off all the sequence bit that is longer than 200bp. so I end up with only a dataset of exactly 200bp. Does anybody know how I can do that in Galaxy. I was thinking of some of the EMBOSS tools, but they only see the first sequence and not all the other sequences in my Fasta file?
Any ideas are welcome. Cheers
Thomas
