What's the difference between b37 and hg19 resources?
Hi, all. I have questions on resource bundles.
Are the 'hg19' bundle files just liftover from 'b37' bundles in UCSC-style? If so, why are there some variants in only one version and not the other? For example, the variant 'rs34872315 (on chr1)' is in b37 version of dbsnp137.excluding_sites_after_129.vcf, but not in hg19 version. At first, I thought it's because of the differences in reference genome (vcf files in the bundle are fit for the accompanying reference sequences). But the reference chromosome 1 was the same in both bundles. Can you help me to understand the difference between b37 and hg19 resource bundles?
