I am trying to get flanking sequence of a list of SNPs. I have the list of SNPs in a excel which I need to convert to the bed format. I looked up for some solution on-line but was not successful. I appreciate any advice on this issue. Thank you.
I'm not aware of any tools that can format an excel file to bed. You'll have to manually format the columns following the BED specification (look here: https://genome.ucsc.edu/FAQ/FAQformat.html#format1), export your file to a tab delimited format and manually add the .bed extension.
