  • stampy error with bwa

    Does the file
    '/data/bwa/bwa_human.rbwt'.
    exist ?

    Is it readable - check permissions.

    Perhaps recreate the reference if all else fails

      Thanks

      The stampy is having some problem with bwa-0.6
      version so i tried with bwa 0.5 and rebuilt all the index's
      now its working

        Does anybody know what returncode -11 means?

        I have created an index for both bwa and stampy. This command works with my hg18.fa but now it is crashing with my hg19.fa


        stampy.py -g /net/ngs/HumanGenome/hg19/hg19 -h /net/ngs/HumanGenome/hg19/hg19 -o my.sam --sanger --bwa=/bin/bwa-0.5.9/bwa --bwaoptions="-q10 /net/ngs/HumanGenome/hg19/hg19.fa" --bwatmpdir=/tmp --keepreforder -M my.fastq.gz

          actually it looks like a BWA problem. I get a core dump when I run BWA by itself. I will check to see if my index is bad.

            Rebuilt your bwa index and try again hope it will work

              I think I have found the problem - it is the index. I think the default "is" indexing method worked with hg18, but it will not work on hg19 (it is too large).

              It took some digging, but this thread mentions it:
              Bridged amplification & clustering followed by sequencing by synthesis. (Genome Analyzer / HiSeq / MiSeq)


              I am now running the index with:

              bwa index -a bwtsw hg19.fa

                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...
