  • Velvet 1.2.10 failing velveth (no contigs)

    Greetings!

    I have used velvet with success before, but I seem to be missing something this time.

    The data is paired-end HiSeq Illumina reads, 100bp (400bp inserts). Velvet is compiled with MAXKMERLENGTH=200, CATEGORIES=10, OPENMP=1.

    The command I am using:

    Code:
    velvet_1.2.10/velveth Assembly1 53,91,8 -shortPaired -separate -fastq HiSeq_100_R1.trimmed.fastq.pe HiSeq_100_R2.trimmed.fastq.pe
    The hash directories are formed for each kmer length, but they just come out with the following files: Log, Sequence, Roadmap -- no contigs, no stats, nothing else.

    The sequences appear to be loading, the end of the standard output is:

    Code:
    ......
    [1262.752392] Inputting sequence 84000000 / 112022250
    [1265.931838] Inputting sequence 42000000 / 112022250
    [1266.165014] Inputting sequence 28000000 / 112022250
    [1266.716441] Inputting sequence 14000000 / 112022250
    [1299.839334]  === Sequences loaded in 399.530517 s
    [1299.845389] Done inputting sequences
    [1299.845391] Destroying splay table
    [1302.434467] Splay table destroyed
    done
    Any idea what I am doing wrong?

    Thanks!

    Well, the superficial problem has been solved: I needed to run velvetg to get the rest of the information. The core issue, that I am an idiot, is harder to fix, but I appreciate everyone's patience with me. Cheers!

      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...
