In late December 2013, the Genome Reference Consortium (GRC) released an updated version of the human reference genome assembly, GRCh38, and submitted these new sequences to GenBank. This is the first time in four years that a new major version of the human genome has become available to the genomics community.
Perhaps you’ve been working on data mapped to the previous assembly (GRCh37) that became available in March 2009, or maybe you are still using an even earlier version, such as NCBI36 from March 2006. Is there a way to reduce the amount of time and effort required to reanalyze your data in the context of the new assembly?
Yes! It’s NCBI’s Genome Remapping Service, or NCBI Remap for short.
