On BioMart, how to set HG18 as the version?
Hi all, I have a list of rs# and I want HG18 coordinates for each one of them. Is there a tool/ utility that can list HG18 coordinates for rs#. Following are a few examples:
rs10010131
rs10046
rs1004819
rs10050860
rs10077785
Thanks in advance.

There sure is: tools include the UCSC Table Browser or GRCh37 BioMart.
correction: Ensembl 54 BioMart
For the latter choose the variation database and the short variation (SNPs/indels) dataset, then supply your IDs as a list.
Here's a sample query using your first rs# - click the "results" button to see output.
Same as GRCh37 (the link I gave) NCBI36, more or less. If you strictly want HG18, use UCSC.
EDIT: sorry I misread your question. HG18 corresponds to NCBI36 which is Ensembl build 54, so you want this BioMart archive.
HG18 on UCSC worked and I get the start and end position of the variants. since I need a single value is the correct position the end or the start?
UCSC database coordinates are zero-based, so add 1 to the start. Which for a single base SNP, gives the same value as the end.
