unknown

UNKNOWN(1)						      General Commands Manual							UNKNOWN(1)

NAME

       unknown - identify possible genotypes for unknowns

SYNOPSIS

       A program to rapidly identify which genotypes are possible for individuals typed as unknowns in the input pedigree.

       unknown [ -cl ]

DESCRIPTION

       unknown infers possible genotypes and mating combinations for parents with unknown genotypes for ilink(1), mlink(1) and linkmap(1).

OPTIONS

       -c     Use conditional allele frequencies.

       -l     Choose a good set of loop breakers automatically.

RETURN VALUE

       0     Successful completion

ERRORS

       10    File not found
       255   Failure

EXAMPLES

       Normally, unknown(1) is run immediately prior to its sister programs, ilink(1), mlink(1) and linkmap(1), like this:

       unknown
       mlink

FILES

       unknown(1) reads the two files pedfile.dat and datafile.dat as its own input and produces various temporary files that are used as input to
       the next program. These temporary files are ipedfile.dat, upedfile.dat, speedfile.dat and newspeedfile.dat.

NOTES

       unknown(1) is part of the FASTLINK package, which is a re-implementation of the LINKAGE suite  of  computer  tools  that  help  investigate
       genetic linkage as first proposed G.M. Lathrop, J.M. Lalouel, C. Julier, and J. Ott.
