Hi everyone

First let me thank all the Team Galaxy, the conference was really great.

Kanwei asked me to send the tool I told him about. It's one of these tools for which you can't know the exact number of output datasets before tool run. Here are the files. It's really simple actually, but it would be nice if I could integrate it in workflows without it having to be the final step. Would it even be possible?

And please ignore the idiotic comments in the files, I was really tired that day.

mpxdata         = sys.argv[1]
barcodes        = sys.argv[2]

output1id       = sys.argv[4]

# Executing deBarcoding

if status != 0:
        print "Demultiplexing failed."


# Reconstructing the output file names as deBarcoding writes them
bc = open(barcodes, "r")
for l in bc.readlines():
        l = l.split()
        if l[0] != "":

        oldnames[i] = oldnames[i] + ".txt"

**Program:** debarcoding.py (v1.0.0)

**Author:**  This is a wrapper for Wave's deBarcoding java tool

**Summary:** This tool demutiplexes data according to a list of barcodes containing a column withe the sample name and a second column with the barcode sequence.

**Usage:**   Here is an example of the java tool's usage::

 Two failed PE runs (multiplex 2 and multiplex8) yielded SE data that can be used for assembly together with the corrected PE ones. To this end, the deBarcoding script from wave was used:

 javasol deBarcoding

 where javasol is an alias to:

 java -cp /g/steinmetz/projects/solexa/java/solexaJ/bin/:/g/steinmetz/projects/solexa/software/picard/trunk/dist/picard-1.18.jar:/g/steinmetz/projects/solexa/software/picard/trunk/dist/sam-1.18.jar

 The command lines were (thanks to Wave for the clarifications):

 For the mplex num. 3, some pre-processing was necessary
