how to correct chromosome number and variant position in a VCF file by the rs#?

Question

[miaowzai]

I have a VCF file that contains some variants with wrong chromosome numbers and wrong positions. For example:

#CHROM  POS ID  REF ALT
0   0   rs25    A   G
25  155233098   rs2037999   T   C

I don't know how this is generated. But all the incorrectly-recorded variants have rs numbers. It's not practical to look for their chromosome number and position one by one. Is there any tool to do this?

Thanks!

If you want to get the position and chromosome of a bunch of rs-numbers you can use the dbSNP batch query.
