% QTLcart -R resource.file
QTLcart will read option values from the file resource.file. The other programs do this, and except for Preplot, will regenerate the file upon exit.
% QTLcart -X corn
Will set the filename stem to corn. The output files will then have names beginning with corn and logical extensions. For example, the map file will be placed in corn.map and the file containing the data from a cross will be in corn.cro. Filenaming conventions should follow the old DOS 8+3 rule due to historical reasons.
