2.1.3 GLMdb

The genetic linkage map database is simply organized as a set of plain text files each corresponding to a single genetic linkage map. The link between the experiment table and the genetic map files is done by using the same stem file name than the name of the mapping experiment declared in the column map of the experiment table. For example the genetic linkage map related to the mapping experiments `exp1' will be stored in a file named exp1.txt. Here a genetic linkage map is represented by a table with the following fields:

• group (string) : the linkage group name.
• marker (string) : the name of the marker.
• position (numeric) : the position of the marker on the linkage group the unit of which is declared in the experiment table.

For example, the genetic linkage map file for the mapping experiments exp1 would be

group marker position 1 lgm0392 0 1 bnlg1178 47.7 1 ts2 102.7 1 bnlg1884 137.5 1 lgm1234 179.3 1 lgm1465 293.2 2 bnlg1092 0 2 bnlg1017 26.8 2 lgm0701 37.4 2 lgm0653 165 2 bnlg1520 190.8 2 dupssr32 218.1 3 bnlg1904 0 3 bnlg1035 36.6 3 bnlg1063 63.1 3 bnlg1182 140.2 3 dupssr8b 161.2
