Hi all,
Does anyone know if it is possible to trim/clip a sequence from the 5' end?
Thank you.
Best, Soetkin.

Hello Soetkin,
A tools search using the keyword trim will bring up the options in
Galaxy, the simplest being the FASTX-toolkit Trim function.
To enable searching, use the the Options menu in the top left tool
menu panel.
Thanks for using Galaxy!

Hi,
with regard to the 5' clipping:
On the main (usegalaxy.org) server: it is possible using the NGS: QC
and manipulation = Generic FASTQ Manipulation = FASTQ Quality
Trimmer by sliding window.
If you are interested, we have recently adapted that tool a bit to
improve speed (5'+3' clipping
Hi all
We are working with chip-chip data of S. cerevisiae (from Affymetrix) and
actually we have two problems and we don´t know if it´s possible to perform in
Galaxy:
1. We use the tool intersect to get the annotation of positive genomic
regions in our file bed. After, we need calculate
My apologies if this has been covered before but I am using Galaxy Main and
wonder if, when running TopHat, you can modify the mapping parameters used
by Bowtie? It seems that the full parameter list for TopHat pertains only
to the reads that aren't mapped by Bowtie (the reads spanning splice

Not all Bowtie parameters can be modified when running Tophat. Which parameters
are you looking to modify and why?

Hi Jeremy,
Thanks for your help. I'm mapping reads from one organism to a related but
different organism, so some of the parameters I'd like to adjust are to
relax mapping stringency -specifically:
-n 3 (allow 3 mismatches in seed)
-e 250 (allow cummulative phred score of 250 [or some other
I think closest to what you want to do in galaxy can be done in cistrome

Unless I am missing some galaxy tool in testing, which other galaxy users
more closely following galaxy test can comment on

I dont think Cistrome can provide sufficient visualization options. In CEAS
analysis it can provide overall picture of genome binding regions or some
relative binding histograms. I beleive what Monica is asking when one has
chip enriched regions how to visualize such selected regions- I will
Hi all (especially Enis :) ),
We are planning to use Amazon (Galaxy CloudMan) to run a workshop for
about 50 people. We won't need to transfer any data during the
workshop, but need the virtual cluster to be reasonably responsive and
cope with:
a) the load on the front end
b) the workshop
Hi Clare,
Jeremy (from the team) ran a similar workshop several months ago and used
some resource intensive tools (e.g., Tophat). We were concerned about the
same scalability issues so we just started 4 separate clusters and divided
the users across those. The approach worked well and it turned
