[Genome] regarding file SNP126orthoPanTro2RheMac2.txt

[saurabh]

Hi,

I downloaded the file SNP126orthoPanTro2RheMac2.txt giving the ancestral
state of SNPs. I wanted to know the difference between the fields "human
observed" and "human allele". Sometimes the "human allele" is different from
the "human observed" irrespective of the strand.
Which of these two ("human observed" or the "human allele") should be
matched with the chimp allele to make sure that chimp has atleast one of the
alleles segregating in humans?

With many thanks,
saurabh
