CalcMatch is a C/C++ software developed by Yun Li that compares two sets of pedigree files. It was initially written to compare imputed genotypes with their true/experimental counterpart but can be used to compare the concordance between any two sets of pedigree files. The input data are in standard Merlin/QTDT format (http://www.sph.umich.edu/csg/abecasis/Merlin/tour/input_files.html).

--match generates a matrix taking values 0,1,2 indicating # of matched alleles. The dimension of the matrix is # of overlapping individuals times # of overlapping markers of the two input pedigree sets.

--trueped --truedat specify the other input pedigree set.

--bySNP is turned on by default to generate SNP specific measures. The output .bySNP will contain the following 6 fields for each SNP:

--accuracyByGeno is an option I added most recently to represent the above (7-20) information in a different way. Similar to --byGeno, it is used on top of --bySNP. It can be used together with --byGeno. It will generate the following fields, after (7-20) is --byGeno is turned on or after the 6th field otherwise.

<br> CalcMatch compares all genotypes overlapping the two input sets. However, when --maskflag is turned on AND --maskped and --maskdat are specified (I know ...) it compares only the following subset of the overlapping genotypes: genotypes either not found (i.e., individual or marker not included) or missing (included but with value 0/0, N/N, ./. etc) in --maskped / --maskdat. These options are useful when some individuals were masked for some SNPs while others masked for a different set of SNPs.
