A sample matrix formatted according to the specifications for the High Throughput Interaction Data Handler file format.
This particular matrix represents hypothetical affinity values between a few S. cerevisiae SH3 domains and some proline-rich peptides. In the two header lines column qualifiers are given as official SGD protein names (first line) or as 'common' names (second line). High Throughput data handler input files can contain additional columns after the column with the line qualifiers.
Please note that the actual file feeded into the data handler should abide by the File Format specifications.
