(212) 960-2507 New York, NY 10032 5 Nov 1993 Documentation to SUBSET program version --------------------------------------- This small utility program allows to extract families from an input file to the HOMOG programs and to produce another input file containing only the families extracted. Files have the following default names: 1) OLDH.DAT holds the original input file with all families, constructed according to the rules required by the HOMOG program. An example of such an input file to the SUBSET program is the file HOMOG.DAT. In comparison with the input files to the HOMOG programs, the following restrictions apply: - All recombination fractions have to be given on a single line (input line no. 4). - The lod scores for each family have to be given on a single line of input. 2) HOMOG.DAT will be the name of the resulting output file, ready for use as input file by the HOMOG programs. 3) SUBSET.DAT is the file holding information on which families should be extracted. Each line in this file corresponds to one selection, ie, one set of families. On each line, each family to be selected has to be listed by its sequential number, corresponding to its position in the original input file, OLDH.DAT. The family numbers have to be given in ascending order, eg, 11 15 16 23. Families with contiguous sequential numbers may be given in abbreviated form, eg, family numbers 7 through 11 would be indicated by -7 11, or as 7 8 9 10 11 (the MTEST program uses the same technique; see description of MTEST.GRP file).
