Is there any existed tool for retrieving DBsnp from Blast output

Question

[309772486]

Hi everyone,

So I have let's say a fasta file consists of 100 sequences.

1. I used Blastn to blast these 100 sequences and got the blast output.

2. I then parse the blast output. For each sequence, I know where the mismatch is comparing to the reference.

3. I want to search in dbsnp for each of the mismatches, if they exists or not.

So I don't know if there is such tool especially for locally search DbSNP data using these mismatch location information?

if you know genomic location of the 100 sequences and the position of the sequences you can answer your question: e.g: Get Rs Number Based On Position

I think you miss a step in your approach. Like Pierre Lindenbaum is suggesting, you'll need to find genomic locations of your variants (or mismatches), probably in vcf format. Then you can annotate your variants (SNP) with known databases such as dbSNP.
