  • bowtie, no .rev files produced

    hi everyone,

    taking my first crack at index building using bowtie.

    I'm trying to build my index using a whole genome assembly in a single fasta file.

    i first ran with all defaults, and bowtie produced only 4 files.

    Both of the .rev files were not generated.

    For now we are not doing paired end reads, so I should probably use the -r (which I haven't done yet). But any thoughts on why I am missing those files?

    oops. wait a sec. first silly question by me (not last). index is still being built....

      sure enough, now I have . rev files...

        You just took several mins to build the index, what is your genome size?

          genome size

          the genome is about 1Gb.

          I made the index using a single fasta file containing the whole genome.

          sound ok?

            it took several hours to build hg18 index, of which the genome size is ~3Gb. what are your options when running the program? I did not think it matters much whether the input is a single fasta file or several fasta files.

              index, tophat_report

              since it was my first try and i had just installed the software, i just used all defaults.

              I'm running on a new cluster with 24 GB memory per node, and 2.4 GHz processors.

              Right now I'm stuck with this problem if anyone has any suggestions.

                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 on Modified Bases...

                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...
