4.2 CFACTOR

CFACTOR transforms data before CMAP or CILINK is invoked. Several program constants allow selection of undocumented features. The only constants subject to change by the user are:
maxlocus       { MAXIMUM NUMBER OF LOCI }
maxall         { MAXIMUM NUMBER  OF ALLELES AT A SINGLE LOCUS }
maxind         { MAXIMUM NUMBER OF INDIVIDUALS }
maxped         { MAXIMUM NUMBER OF PEDIGREES AFTER FACTORIZATION}

          { BINARY (FACTOR UNION) SYSTEM }

maxfact        {MAXIMUM NUMBER OF BINARY CODES AT A SINGLE LOCUS}

elimu=false;   {Eliminate locus when a parent cannot be inferred}
elimb=false;   {Eliminate locus when neither parent can be inferred}
esame=false;   {Eliminate locus when parents could be homozygote}

          { OTHERS }

maxn           { MAXIMUM NUMBER OF ITERATED PARAMETERS }

MAXPED cannot be determined before CFACTOR is applied to the data, but twice the actual number of pedigrees is probably a safe minimum value.

CFACTOR takes IPEDFILE and DATAFILE as input, and produces TEMPPED and TEMPDAT. When CFACTOR finishes it displays in a box on screen the (new) number of pedigrees and total number of indiv- iduals it wrote into the TEMPPED file. To read this information you may have to temporarily stop the PEDIN batch file (using Ctrl-S, and use Ctrl-Q to get it going again). Alternatively, insert a PAUSE statement after each occurrence of the CFACTOR statement such that the program stops after CFACTOR has executed.
