Original AFLP data matrix

this file has the following structure:
- data for individuals are in rows, and loci are in columns
- additionally, there are two columns in the beginning giving
the population (pop), and species (species) of each individual;
pop is either the population identifier
[aga1 = aga-1, aga3 = aga-3, hyb1 = hyb-1, hyb2 = hyb-2, pha1 = pha-1,
pha3 = pha-3]
or indicates individuals repeated for error estimation
[con (control) = individuals repeated on each plate, with A-E as part of
the identifier indicating the plate;
test = individuals repeated on a different plate]
- the last row (quality) gives an indication of the peak quality for each
locus (separation from other peaks, clarity of peak)
[A - very good, B - good, C - bad, X - extremely bad; intermediate
categories, e.g. A-B for between A and B are used as well;
generally A and B are good for use]
