Motivation

For @isamtalves : annotate a VCF for ancestral allele using data from 1000 genomes:

Manifest

manifest is a tab delimited file.

empty lines are ignored

lines starting with ‘#’ are ignored

three columns:

note to self: building the manifest

 find ${PWD} -name "*.fa" | sort -V | while read F; do echo "$F" | sed 's%/commun/data/pubdb/ftp.1000genomes.ebi.ac.uk/vol1/ftp/phase1/analysis_results/supporting/human_ancestor_GRCh37_e59/human_ancestor_%%' | sed 's/.fa//' | tr -d "\n" && echo -ne "\t" &&  head -n 1 $F | cut -c 2- | tr -d '\n' && echo -en "\t" && echo $F  ; done | sed 's/^\([^\t]*\)/\1|chr\1/'
