  • STAR aligner issue

    I am trying to align some paired end RNAseq data using STAR (version 2.3.0e), but I'm having an issue with the alignment. My code is:

    $HOME/bin/STAR_2.3.0e/STAR --genomeDir /srv/mds01/shared/Epigenetics/Rnaseq/transcripts/STAR --readFilesIn Colon_R1_S6_L20_final.fq.gz.val_paired_1.fq.gz Colon_R2_S6_L20_final.fq.gz.val_paired_2.fq.gz --readFilesCommand zcat --runThreadN 4 --genomeLoad NoSharedMemory --outFileNamePrefix ../STAR/colon.paired --outFilterScoreMin 0 --outFilterScoreMinOverLread 0 --outFilterMatchNmin 0 --outFilterMatchNminOverLread 0

    I receive the following output in the command line:

    May 20 11:01:39 ..... Started STAR run
    May 20 11:02:23 ..... Started mapping

    The run only lasts about 5 minutes. When I check the end of the pairedLog.out file, I see the following message:

    alignIntronMax=alignMatesGapMax=0, the max intron size will be approximately determined by (2^winBinNbits)*winAnchorDistNbins=589824
    EXITING because of a BUG: nTr=0 in outputAlignments.cpp

    Does anyone have any experience with this sort of issue? Thanks.

      Hi @shocker8786,

      please try the latest STAR patch:
      http://it-collab01.cshl.edu/shares/g...AR_2.3.1z4.tgz

      If it does not work, please try running it without
      "--outFilterScoreMin 0 --outFilterScoreMinOverLread 0 --outFilterMatchNmin 0 --outFilterMatchNminOverLread 0".

      If it still does not work, please send me the Log.out file.

      Cheers
      Alex

          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...
