[galaxy-user] Initial QC and grooming for Illumina HiSeq2000 paired end RNAseq data

I am trying to do RNAseq analysis on Paired end data from the Hiseq2000. I have about 50 files for each sample (25 forward and 25 reverse - although each sample has a different number of files). I think that I need to: -convert them into FASTQ sanger format using the FASTSQ groomer tool -check the quality using the FASTQqc tool I don't know how to handle this many files. Do I have to groom and run the QC for each file? Should I join the paired files and run both tools on each pair, or should I combine all of the data for each sample (which I don't know how to do) and then groom and run the QC for all of the reads for the sample. Thanks in advance for advice Lindsey
