Hello, I am new in using Galaxy and I am working on .bam files generated by our sequencing platform, using the LifeScope software associated to ABI 5500 sequencer. I uploaded my files on a galaxy browser ( http://galaxy.raetschlab.org) and I tried to run cufflink assemble and quantify reads expression levels for each file. However, when I run cufflinks (using default parameters) the output is an empty file. What is going wrong? Should I use special parameters? Are the .bam files generated by LifeScope suitable for cufflink analysis or should I transform the xsq ABI output in a fastq and then apply TopHat? I thank you very much for your help Davide --- Davide Degli Esposti, PhD Epigenetic (EGE) Group International Agency for Research on Cancer Tel. +33 4 72738036 Fax. +33 4 72738322 150, cours Albert Thomas 69372 Lyon Cedex 08 France ----------------------------------------------------------------------- This message and its attachments are strictly confidential.
