    Label for every BAM in Cuffdiff

    Hi!
    Im running Cuffdiff 2.1.1 now on some samples, but Im struggling with the --labels option.

    It allows me only to name the conditions, but I really want to name the individual BAMs.

    I want to do this because its easier when doing downstream analyses.


    Anyone knows? Thanks.

    Or, if not possible to label individual BAMs, how do I know which BAMs corresponds to cummerbunds "sample_names"?

      The most tedious way must to manually rename using "find & replace" in all the "read_group_tracking" - files...


      But still, the replicates have an odd organisation, so I don't know which BAM correspond to which replicate.

        I guess nobody knows?

        I have emailed the Cuffdiff authors, if they answer Ill post it here.

          If you would like to use the bam file names instead of conditions, you loose some statistical power, bacuse you can not handle replicates. If you do not have replicates, you can use the bam file name as label.

            Well, I don't know if I understand you correctly.

            Of course Ill use all nye replicates, its just I want to know which BAM has which name in the read-group-files.

            If I have 5 replicates in each condition, I want to know that BAM 1 = condition 1 & replicate name 1. etc.

            In Cuffdiffs output files this is however impossible to know. Condition is ok, but the replicate name is very confusing.

                Got it!

                In Cuffdiff 2.1.1 it gives a "read_groups.info" file. Finally...

                  Nine Things a Sample Prep Scientist Thinks About Before Sequencing
                  by SEQadmin2


                  I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.


                  Here are nine questions we think about, in roughly the order they matter, before...

                  From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
                  by SEQadmin2


                  Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


                  The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
