Refget: standardised access to reference sequences
Description
All sequencing-based genomic analysis uses a genomic “reference sequence” — a baseline of knowledge against which variations are observed. There are multiple human reference sequences of increasing accuracy and different organizations refer to the same sequence using different names or reuse names to refer to different reference releases. Reliable, reproducible genomic analysis depends on clear provenance back to reference data. The GA4GH refget API enables access to reference genomic sequences without ambiguity from different databases and servers using a checksum identifier based on the sequence content itself.
