Fairy computes multi-sample contig coverage for metagenome-assembled genome (MAG) binning.
Fairy is used after metagenomic assembly and before binning. It can
- Calculate coverage 100x-1000x faster than read alignment (e.g. BWA)
- Give comparable bins for multi-sample binning (short read or nanopore reads)
- Output formats that are compatible with MetaBAT2, MaxBin2, SemiBin2, and more
Caveats:
- Don't use fairy for single-sample binning
- Don't use fairy for PacBio HiFi

Fairy usage for SemiBin2 is different than other tools: SemiBin2 requires separate coverage files for each read sample -- other tools require a single coverage matrix.
The default output format from Fairy is the MetaBAT2 format. Any tool using this or the format from the other 2 binners work also with Fairys coverage files!
