Every so often we get asked how to convert genomic coordinates from an earlier assembly to a later one, or even between genomes. There are several online locations to do this. In this tip of the week, I’m going to introduce you to Galaxy’s Liftover tool and point out too that UCSC Genome Browser and Flybase have similar tools (as do others I’m sure, know of any?). With this tool, you can take your coordinates and easily convert them to coordinates of a later assembly. Btw, Galaxy is a great analysis tool.
