<p class=MsoNormal>I was looking for help on how to use data from 240S Illumina
chips for linkage. I ran a family on these chips which genotype 240,000 SNPs across
the genome. Unfortunately none of the linkage programs that I have looked at are
able to handle this amount of data. Even SNPlink which is designed to cut down
the large numbers of SNPs does not work with such a large dataset. One approach
that I was thinking of following is to match the SNPs on Illumina’s
linkage panel V to the SNPs that I have generated using the 240S SNP chip. Problem
is that not all of the linkage panel V SNPs are on the 240S Illumina SNP chip,
so I may have to take nearby SNPs. My questions are as follows:<o:p></o:p></p>
