Hi Rathi! I wrote a tophat wrapper myself- you can use it if u want, the files are attached. you need to adapt the BOWTIE_INDEXES path in the toohatwrapper.py and the bowtie path. if these variables are already set then you can just remove the lines between "#path settings" and "#path settings end". And you must include the tophat.xml in the tool-conf.xml in the main galaxy folder - in a section of your choice. Let me know if u find any errors- greetings mat Rathi Thiagarajan schrieb:

Hello there,

I was really pleased to see that you have the NGS toolbox within Galaxy. I was wondering if there are any plans to include TopHat (http://tophat.cbcb.umd.edu/)and/or Cufflinks (http://cufflinks.cbcb.umd.edu/) into the toolbox as this would be really beneficial.

Also do you have tools to convert fastq format to SAM?

Thanking you in advance.

Cheers, Rathi
