  • Bad hash size error in Jellyfish

    Hi all,

    I'm using Trinity for the first time on some data we've been sent by a colleague. I'm getting this error during the Jellyfish stage - I wondered if any of you have any insights?

    Here's the error:

    perl Trinity.pl --seqType fq --JM 30G --single ../../../../data/Easp_VT.fastq --CPU 4
    Current settings:
    time(seconds) unlimited
    file(blocks) unlimited
    data(kbytes) unlimited
    stack(kbytes) 8192
    coredump(blocks) 0
    memory(kbytes) unlimited
    locked memory(kbytes) 64
    process unlimited
    nofiles 1024
    vmemory(kbytes) unlimited
    locks unlimited


    -since butterfly will eventually be run, lets test for proper execution of java

    -we properly captured the java failure status, as needed. Looking good.
    Java tests succeeded.

    You *may* be running out of memory. What is the memory size in your system? Using a small '-JM' size could be useful. It should only increase the time to run Jellyfish by a small amount.

      I'd also check the version of perl, some older versions have a memory cap.

        Thanks, it does appear to have been a memory problem and reducing the -Jm seems to have solved it.

          Recent Advances in Sequencing Analysis Tools
          by seqadmin


          The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

          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...
