Hi Prithvi,

I am sorry for the delayed response. Do you have the identifiers for the 
200,000 SNPs (rs####)? If so, the best way to get the information you 
need is to use the Table Browser to get the selected fields for your 
SNPs of interest and send that output to galaxy where you can use their 
intersection tool to intersect the SNPs with a genes track.

Click 'Tables' in the top blue menu bar and select your clade, genome, 
and assembly of interest. Then  make the following selections:
group: 'Variation and Repeats'
track: latest SNP track for your assembly
table: use the default table (snp###)
region: genome
identifiers: click 'upload list'; upload the file with your identifiers 
and click submit
output format: selected fields from primary and related tables; and 
check the box next to Galaxy (to send output to Galaxy)

Click 'get output'. Select the fields you want from table. You'll 
definitely want to select 'func' because this will provide you with the 
information you wanted about where the snp is located (coding, intron, 
etc) and probably probably also want the name, chrom, strand, 
chromStart, and chromEnd fields. Click 'done with selections' and then 
'Send query to Galaxy'.

 From Galaxy, you can go to 'Get Data' and then 'UCSC Table Browser' and 
do a query to get all the genes from your gene track of choice. The 
query results will appear to the right of the page (where you should 
also see the data from your snp query that you sent over. Then click on 
the 'Operate on Genomic intervals' link on the left side and click on 
the 'Join' (the intervals of two queries side-by-side) link. Select the 
two queries that you just did to create a join between them. If the gene 
track data isn't showing up as an option for the join, click the 'Edit 
attributes' pencil icon of that query (in the history area on the right) 
and change the data type to 'interval'. The eye icon next to the results 
will allow you to display the data and you will be able to see the snps, 
their regions, their function

Please don't hesitate to contact the mail list again if you have any 
further questions about the UCSC Genome Browser. For questions about 
using Galaxy please contact the Galaxy helpdesk via the following email:
