  • SOLiD RNAseq questions using galaxy and cuffdiff

    hi all,

    I'm a bit of a noob here. I'm working through some transcriptome data using galaxy and am having a couple troubles.

    I have SOLiD data, paired end, but with the F5-BC tag. I have watched the screencast on the galaxy page which says that solid mapping for paired ends has reads that go the same direction, but the SOLiD F5-BC tag actually goes the opposite direction apparently. So, question 1: can galaxy figure this out?

    Next, I've done a trial run with this data and gone through to cuffcompare without problems although I couldn't get cuffdiff to run within galaxy. No biggie, though because I could run it in the terminal. Sweet. But I have a question about the output. When I look at the gene expression file, in sample1 and sample2 columns there are codes ranging from q1-q5. What do these mean? I'm only comparing one sample with another sample and don't really get what is going on here.

    Any advice would be greatly appreciated.

    About your first question - I'm trying to figure it out my self...
    It seems that Galaxy can only handle mate-paired or single-pair reads, but not paired-ends....

    Does anyone know how can I handle a paired-end reads in Galaxy - and if I can't - how can I convert the reads to fastq format (isn't solid2fastq.pl works only for single-pair/mate-pair?), so that I could upload the files to Galaxy and keep my pipeline?
    Thanks!

      Essential Discoveries and Tools in Epitranscriptomics
      by seqadmin




      The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
