Summary: Select the current map for analysis Argument: < genetic map > Default: display the current map selected
The 'use' command is used to select the current map that the 'scan' command will operate on. It is called in the following manner:
use < marker > < distance > < marker > < distance > < marker > ...
Markers may be specified numerically (1 being the first listed in the marker locus file - the affectation locus does not count in this numbering scheme as it does in the Linkage parameter file) or by the names specified in the comment area for each marker. If a map is specified in the Linkage parameter file, it will be entered automatically during the "load markers" step. Enter "use" without arguments to see what current linkage map has been entered. IF THERE IS NO LINKAGE MAP IN THE LINKAGE PARAMETER FILE, ONE MUST BE ENTERED USING THE "USE" COMMAND BEFORE ANY ANALYSIS CAN TAKE PLACE.
Distances may be specified as either recombination-fractions or centiMorgans, with the necessary assumption that if EVERY distance is less than 0.5, they are all assumed to be recombination-fractions, otherwise (if ANY distance is greater than 0.5) they are interpreted as centiMorgan distances.
