Hello,

I'm try to select shared variant between patients using VCF-VCFintersect but appear this error message:

unable to find FASTA index entry for 'M'

if I use hg_g1k as reference genome

or

unable to find FASTA index entry for '1'

If I sue hg19 as reference genome

thanks in advance for any help

Hello,

The issue is a genome mismatch problem. "hg_g1k_b37" is from 1000 Genomes and with a mitochondrial chromosome named as "MT".  "hg19" is from UCSC and uses chromosome named like "chr1, chr2, ...chrM, chrX...".  More about this type of mismatch is here:

Use the same exact reference genome with tools as the VCF datasets were created against. Perhaps the version from Ensembl? If needed, load it as a custom reference genome and use it that way. Instructions:
