    Galaxy Cufflinks -> cummeRbund?

    Hi,

    I found a useful thread here that is related to what I am doing, but not quite. Galaxy may be missing some files I need? I don't know. Here is what I want to do.

    1. Read in cuffSet object using readCufflinks()
    cuffData = readCufflinks("data")

    2. Once I have this cuffData, I want to draw a volcano plot as follows
    sigGene = csVolcano(genes(cuffData), "treatment1", "treatment2")

    That's it.

    My problems are as follows:
    1. See my attached files. I need to save galaxy output to be recognized by readCufflinks(). However, see my error message. I am going to need all the default files readCufflinks requires. But I don't see where galaxy saved isoforms.fpkm_tracking. I just don't see it? Is it transcript FPKM tracking?

    2. If all I want is to make a volcano plot as mentioned in 2. Can I just load the gene diff and fpkm tracking file for readCufflinks? Or do I need all the output from galaxy?

    3. Right now I am manually saving the output files and renaming them, but is there a better way to output galaxy cufflink output?

    I think I may have found the solution here. However, before I can claim this is solved, can I have some folks in the community confirm some things for me? For example, that transcript differention expression from galaxy output is actually isoform.diff and so on? Why would they name files different like this from cuffdiff output defaults? I am just trying to figure out what is galaxy calling an output and what cummeRbund thinks it is. I am, I think, super close.

      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.
