  • Tophat2.0.8b segment-junc err=1

    Hi,
    Last week I upgraded last version of Tophat; so now I'm using Tophat 2.0.8b with bowtie 1.0.0 (I need to align color space reads).
    Before I used Tophat 1.4.1 and bowtie 0.12.8, and I never have any problems.

    So I launch this command (the same of previous version except for --bowtie1) :
    tophat -C --bowtie1 --no-coverage-search --library-type fr-secondstrand -G $annotation_file -g 10 -p 12 -r 90 -o $output_path $reference_file $csfastaF3 $csfastaF5
    with reference_file="/.../ENSEMBL_HG19/Homo_sapiens.GRCh37.71.dna.23chr_c"

    So, now this message appers:

    Any suggestions (maybe also from autors)?

      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...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
