Hello Archie, This SNP maps to more than one location in both genomes.
To get the mapping for either of the locations in hg18 to both in hg19 use the option "multiple". When this box is checked, a BED file is required, the minimum is actually a BED4. This would convert your position to: chr17 33706710 33706711 1 (The trailing 1 is just a place-holder, you could use a meaningful value if you wanted to). Please try and see if this works for you, too, Jennifer --------------------------------- Jennifer Jackson UCSC Genome Bioinformatics Group http://genome.ucsc.edu/ On 2/11/10 2:23 PM, Archie Russell wrote: > Hi guys, > > I'm looking at this region > > chr17:33706711-33706711 (there's a SNP there) on hg18 > > I plugged this into liftOver; it can't be mapped: > > #Deleted in new > > chr17:33706711-33706711 > > > But the SNP in that region is in both builds (in hg19 it has two locations), > as is the gene.
