Please can you help me.
How do i find out which version of dbSNP is used by a particular version of ensembl.
For example I am looking at an older verison of ensembl(58) and I want to know which database build of dbsnp it has imported variations from. All of the snps i can see in e!58 say they are from dbsnp 130 but i would like to know where i can find the mapping/association definitely.
I have also been unable to find a list of the dates of the different dbSNP releases. I found this page but nothing else http://www.ncbi.nlm.nih.gov/books/NBK44478/
Also on this page, what does it mean that bos taurus is using current build 131 http://www.ncbi.nlm.nih.gov/SNP/snp_summary.cgi It also says it has 2,446,173 new snps when it only has 2210641 in total. I presume some of those submissions refer to more data for known snps then? I don't understand how the cow data has new submissions but is only an older build number. Wouldn't it be rebuilt (whatever that means) to include the new submissions? I would really appreciate an explanation of how the organism build number applies to the database build number and then how the number of new submissions applies to that.
Given the dbsnp version information from ensembl i would then like to query the relevant dbsnp build of dbsnp using eutils but i dont know exactly what the limits on this page mean:
The obvious candiates are create build id and update build id but i don't know the difference between a create build and an update build id. I presume it is the build in which the snp is created and the build in which the snp is updated from the names :) But i tredi this "bos taurus"[Organism] AND ("132"[CBID] OR "131"[CBID]) and got no results.
My main concern is that i don't understand the different build numbers for different organisms
thanks a lot for your help
