Pre‐built databases

Pre-sketched databases available for download below. All databases work from sylph version 0.3.x onwards.

• Use the http://faust.compbio.cs.cmu.edu links if possible. We provide mirrors on google cloud, but this costs us more money.

Example usage:

wget http://faust.compbio.cs.cmu.edu/sylph-stuff/gtdb-r220-c200-dbv1.syldb
sylph profile my_sample.sylsp v0.3-c200-gtdb-r214.syldb -t 30 > results.tsv

Taxonomy usage:

Most the databases have associated taxonomies that sylph can utilize. See https://github.com/bluenote-1577/sylph-tax for more information.
