  • VCF to MAF (Mutation Annotation Format)?



    Can anybody point me to a tool that can convert a vcf file to Mutation Annotation Format (MAF) file?

    That will be great!

    Thanks

    Convert Variant Call Format to Mutation Annotation Format

    I am also looking for a tool to convert variant call format files (.vcf) to mutation annotation format files.

    There is a python script vcf2maf available on github but this code looks for specific fields in the vcf header that are unique to TCGA .vcf files. When I run this code on my data it errors out due to missing fields.

    Thanks,
    Mike

      vcf to maf

      I am also looking for a tool that will do this, and I was wondering how people usually generate MAF files? Don't you usually need the original alignments (BAM files)?

      I am working with data where I was only given the vcf file and I dont' know if it's possible to generate MAF without bam files or original alignment files.

      Anybody know?

        Convert VCF (Variant Call Format) into TCGA MAF (Mutation Annotation Format)


        github.com/cbare/vcf2maf‎

        Read in a vcf file outputted by SNPEff. Parse and output the data in tcga maf format

        code.google.com/p/ngs-analysis/source/browse/modules/somatic/vcf2maf.py

          I have heard of this script, but I heard that it only works on very specific input.

            I was trying to use Oncotator, which takes MAF file as input. What I ended up doing is simply extracting the relevant columns from a VCF file and arranging them in the correct order.
            Code:
            cat file.vcf | \
            awk -F $'\t' 'BEGIN {OFS=FS} {print $1,$2,$2,$4,$5,"","hg19"}' | \
            sed 's/,\([ACGT]\)\t/\t\1/g' | \
            grep -v "#" | \
            awk 'NR==1{print "Chromosome\tStart_Position\tEnd_Position\tReference_Allele\tTumor_Seq_Allele1\tTumor_Seq_Allele2\tNCBI_Build"}1' \
            > file.maf
            It's not perfect, but for the purpose of Oncotator, this was sufficient.

              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...

              Strategies for Sequencing Challenging Samples
              by seqadmin


              Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
