Hi, Am a complete newbie, at investigating Galaxy. I found my question(Scatter-Gather data) in the mailing list about 10 months ago, but did not see any action on it hence asking again. I want to create a sub work flow where, 1. I scatter/split a file into little files, 2. Find the occurrence of each sequence in the little files, within a huge reference file and recreate the little files with the index positions appended against each sequence, as to where they appeared in the huge file. 3. Gather back the little files into a whole big file. Can you tell me if it is possible to do this in Galaxy? If yes, are there any existing/in-built tools that I can use to do the same? Thank you, Sonali Amonkar DISCLAIMER ========== This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
