## Verion 1.2 (May 10, 2022)
* removed DIAMOND database to reduce space
* DIAMOND database is now built locally after download

## Version 1.1 (Mar 18, 2022)
* added 988 complete Inovirus genomes from Roux et al. (PMID 31332386)
* added 5541 complete phage genomes from INPHARED (https://github.com/RyanCook94/inphared)
* INPHARED genomes were filtered to be distinct from existing CheckV genomes
* both sets of genomes were screened by CheckV to remove likely genome fragments and non-viral sequences
* sequences files were updated with new seqs (checkv_reps.fna, checkv_reps.faa, checkv_reps.dmnd)
* metadata files were NOT updated with new seqs (checkv_circular.tsv, checkv_genbank.tsv, & checkv_clusters.tsv)
* new database release should improve completeness estimates for Inovirus and possibly other groups

## Version 1.0 (Feb 2, 2021)
* stable v1.0 release

## Version 0.6 (May 6, 2020)
* added hmm_db/genome_lengths.tsv
* publication release

genome_db
|
|-checkv_circular.tsv
  metadata for circular viral contigs
|-checkv_genbank.tsv
  metadata for genbank genomes
|-checkv_clusters.tsv
  information for non-redundant genomes
  these are clustered at 95% ANI over 85% the length of both genomes
  clustering performed using a greedy centroid-based algorithm
  the cluster representatives are used by CheckV for mapping
|-checkv_reps.faa
  proteins for representative genomes
|-checkv_reps.fna
  genomic sequences for representative genomes
  terminal repeat trimmed for circular viral contigs
|-checkv_reps.dmnd
  DIAMOND database of protein sequences
|-checkv_reps.tsv
  basic info on representative genomes
|-checkv_error.tsv
  lookup table used to report error and assign confidence levels to CheckV completeness estimates

hmm_db
|
|-checkv_hmms.tsv
  metadata for 15,959 CheckV HMMs
|-checkv_hmms
  directory of HMMs
  each file contains 200 HMMs
  HMMs split into multiple files for improved parallelization
|-genome_lengths.tsv
  genome length statistics for each HMM
