MaCH: Pedigree with Integer Allele Codes

From Genome Analysis Wiki
Jump to: navigation, search

For compatibility with older applications that only accept integer allele codes in pedigree files, MaCH can accept pedigree files that encode bases A, C, G, T as 1, 2, 3, 4. Here is an example:

 <Example of a pedigree file with numerically coded alleles>
 FAM1001   ID1234  0   0   M   1 1   1 2   2 2
 FAM1002   ID5678  0   0   F   1 2   2 2   3 3
 ...
 <End of pedigree file>

The corresponding base-pair coded pedigree would be:

 <Example of a pedigree file with base-pair coded alleles>
 FAM1001   ID1234  0   0   M   A A   A C   C C
 FAM1002   ID5678  0   0   F   A C   C C   G G
 ...
 <End of pedigree file>
