  • Trinity freezes on clustering

    Recently we tried to replicate our previous result of de novo assembly using Trinity 2.0.6.
    and
    Bowtie 1.2.0

    First it seems working but Just after
    "Trinity Phase 1: Clustering of RNA-Seq Reads",
    on the command

    cmd: bash -c " set -o pipefail; bowtie -a -m 20 --best --strata --threads 32 --chunkmbs 512 -q -S -f \
    ./chrysalis/inchworm.K25.L25.fa.min100 both.fa | samtools view -@ 32 -F4 -Sb - | samtools sort -@ 32 -no - - > /project/hikaku_db/nono/sync/opium_poppy2/trinity.3s1/trinity.POL2/chrysalis/iworm.bowtie.nameSorted.bam" 2>/dev/null
    1
    it seems to freeze for hours and days without any output.

    Also, I run the corresponding command directly, instead of use pipeline, save the output for a temporary file, but the process froze again before finishing to write the temporal output file.

    Does anyone has some comment or suggestion to solve the problem ?

    I have edited the cmd to use bowtie version 1.0.0, and it worked.

    Can someone guess what was the problem?

      The same trouble occurred using
      Trinity 2.4.0
      Bowtie 2.3.1
      Samtools 1.4

      It goes to the line

      * Running CMD: bash -c " set -o pipefail;bowtie2 --local -k 2 --threads 16 -f --score-min G,46,0 \
      -x chrysalis/inchworm.K25.L25.fa.min100 both.fa | samtools view - @ 16 -F4 -Sb - | samtools \
      sort -m 4294967296 -@ 16 -no - - > chrysalis/iworm.bowtie.nameSorted.bam"

      and stalled without creating output file.

          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...
