An FM-index representation of a de Bruijn graph.
The code in this repository is a stand-alone version of the FM-index from SGA (github/jts/sga). It is licensed under GPLv3.
The code has no dependencies and should build by just running:
make
To test the code is functioning correctly, you can run:
make test
This will download human chromosome 20, index it with SGA then perform test queries using dbgfm. You will need to modify the Makefile to point to your version of SGA. This requires bwtdisk is installed.
A simple API for querying the structure of the de Bruijn graph is provided. See dbg_query.h and the test driver.
