    CD-HIT-EST-2D Error: segmentation fault ('core' dumped)

    Hello,

    I am using CD-HIT-EST-2D in order to compare two contigs files in fasta format. I have been using it for several files and it worked properly until I got an error with two files. The error is: segmentation fault ('core' dumped). I give you the commands and the output:

    -----------------
    [joel@localhost results]$ /programs/cd-hit-v4.6.1-2012-08-27/./cd-hit-est-2d -i Contig_Leg_500Mb.fasta -i2 Contig_Leg_500Mb_15ntout.fasta -o Prueb.fasta -c 0.95 -n 8
    ================================================================
    Program: CD-HIT, V4.6 (+OpenMP), Feb 26 2014, 12:02:11
    Command: /programs/cd-hit-v4.6.1-2012-08-27/./cd-hit-est-2d -i
    Contig_Leg_500Mb.fasta -i2
    Contig_Leg_500Mb_15ntout.fasta -o Prueb.fasta -c 0.95
    -n 8

    Output
    ----------------------------------------------------------------
    total seq in db1: 37276
    total seq in db2: 28500
    longest and shortest : 14632 and 201
    Total letters: 19048606
    Sequences have been sorted
    longest and shortest : 12192 and 201
    Total letters: 13606287

    Approximated minimal memory consumption:
    Sequence : 36M
    Buffer : 1 X 15M = 15M
    Table : 1 X 1M = 1M
    Miscellaneous : 0M
    Total : 54M

    Table limit with the given memory limit:
    Max number of representatives: 0
    Max number of word counting entries: 93208177

    Segmentation fault (`core' dumped)

    -----------------

    I have checked the fasta files and they look good. Besides, I have tried to use CD-HIT-EST with each file and it worked, so I don't know where is the problem. I also used CD-HIT-EST-2D for files with more and larger sequences and it worked so the problem is not with the memory limitations.
    Did someone have the same problem?

    Thanks.

    Hi Joel 91.
    I have got the same problem. Have you fixed the issue?
    Best regards.

      Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
      by SEQadmin2



      Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

      Cancer Drug Resistance: The Lingering Barrier to Rising Survival
      by SEQadmin2



      Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

      There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

      Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by GATTACAT
      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
