Dear all, I am a Phd student working on chicken genomics, with limited experience in the bio-informatics field. I performed an RNA-Seq experiment with single end 50 bp reads to find differential gene expressions between different groups. I have mapped this data with Tophat and used flagstat and Picard to check the number of mapped reads. To check the coverage of my genome, I could use the number of mapped reads and multiply this by the read length and divide by the genome size, but of course since I used mRNA as input material, average coverage will be low (only exons presents). I would like to use the Samtools Depth (as I read on SeqAnswers) to get the average coverage for a coveraged base AND the total base coverage, but this does not seem to be included in Galaxy. Does anyone know a way around this? Other useful tips and tricks are also welcomed. Thank you very much. Have a nice day. Yours Sincerely, Els --- Ir.
