    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

                Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
                by SEQadmin2



                CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

                Despite this, “CRISPR helped turn genome editing from a specialized technique into

                Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
                by SEQadmin2


                Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

                The systematic characterization of the human proteome has

                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.
