Re: Unmatched MBF data value while analyzing SNP markers

Dear Arthur,

Thank you for your comments.
 
After testing the possibilities you indicated in your email, the
repeated message 'Unmatched MBF data value...' cluttering the .asr file
disappeared.

The source of the problem was the way parents and clones were coded in
the pedigree and data files. In the pedigree file, I had 17 trees as the
parents and 136 trees as clones. Instead of coding clones starting with
18, I had clone codes starting with 101 (to 236). The clones in the data
file were also coded from 101 to 136.

The program looks for marker data for the non-existent clones (18 to
100) because it reorders the trees in the pedigree file from 1 to 153
(17+136) and reports the 'Unmatched MFB data value...' message for all
non-existent clones and repeats the same message for about 3000 markers.

That makes the .asr output file very large!
