    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:


      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

        I downloaded the patch and everything seems to be running properly now. Thank you very much!

          Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
          by SEQadmin2



          CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

          Despite this, “CRISPR helped turn genome editing from a specialized technique into

          Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
          by SEQadmin2


          Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

          The systematic characterization of the human proteome has
