Load a tab separated file with the first row containing column headers (field names). The first column should be a Sequence Identifier, such as the ST for MLST data. Other columns should be the different loci used in the typing scheme.

Example of a MLST dataset for Streptococcus dysgalactiae subspecies equisimilis:

 ST      gki     gtr     murI    mutS    recP    xpt     yqiZ
 1       10      6       6       6       12      13      8
 2       5       4       4       1       2       15      2
 3       5       3       4       1       6       2       1
 4       2       2       4       1       8       7       2
 5       2       2       4       1       12      12      7
 6       1       3       1       1       1       1       4
 7       1       1       1       1       1       1       3
 8       1       1       1       1       1       1       4

This files should not contain missing data. If any allele missing data is found the entire line is discarded.
