  • This format is for a compressed archive containing two (a PED and a MAP) files. Babelomics can read .zip, .gz and .tar.gz files but needs to be able to uncompressed data without finding any folder structure.

  • The PED file is a white-space (space or tab) delimited file: the first six columns are mandatory:

     Family ID
     Individual ID
     Paternal ID
     Maternal ID
     Sex (1=male; 2=female; other=unknown)
     Phenotype
  • The MAP file describes for each line, a single marker and must contain exactly 4 columns:
    chromosome (1-22, X, Y or 0 if unplaced)
     rs# or snp identifier
     Genetic distance (morgans)
     Base-pair position (bp units)
