Metabuli v1.1.1

• Version packaged in Metabuli App
• Import the latest MMseqs2 as a git submodule
• Added FASTA/Q format validators: fastq_utils and fasta_validator
• Added database validation function: validatedb
• Added classifiedRefiner for filtering or manipulating per-read classification result file.
• Improved createnewtaxalist.
• Improved thread-safety of the database creation process.

Metabuli v1.1.0

• Fix errors in v1.0.9
• Custom DB creation became easier
• Improve updateDB command

Metabuli v1.0.9

DB creation process improved

• Added updateDB module for adding new sequences to an existing database.
• Added --cds-info parameter in the build module. Users can provide CDS information to skip Prodigal's gene prediction.
  • Currently, only NCBI RefSeq or GenBank CDS files (*cds_from_genomic.fna) are supported.
  • For the accessions included in the files, the provided CDS info will be used, skipping Prodigal's gene prediction.
• Added --max-ram parameter to the build module.
• Added compatibility with taxdump files generated using taxonkit.
• 1.0.9-2: Fixations for bioconda

Metabuli v1.0.8

• Added extract module: It extracts reads classified under a specific taxon at any ranks. It can be used after running classify.

Metabuli v1.0.7

Metabuli became faster than v1.0.6

• Dataset

Metabuli v1.0.6

Windows OS is supported

Metabuli v1.0.5

The CMake file was edited to pass the Bioconda PR test.
Other than that it is the same as v1.0.4.

Metabuli v1.0.4

• Fixed a minor reproducibility issue.
• Fixed a performance-harming bug occurring with sequences containing lowercased bases.
• Auto adjustment of --match-per-kmer parameter. Issue #20 solved.
• Record version info. in db.parameter

Metabuli v1.0.3

• New parameter: --tie-ratio in classify module. [default 0.95]
  When the best matching species has a score MAX, species with score >= (MAX * --tie-ratio) is considered as a tie to the best score. When tie species occur for a read, the read is classified into their LCA.

Metabuli v1.0.2

v1.0.2

• --accession-level option for build and classify workflow: It reports not only the taxon but also the accession of the best match.
• Fix minor bugs in build and classify workflow.
• Generate taxonomyDB during build and load it during classify workflow for faster loading of taxonomy information.
• Support gzipped FASTA/FASTQ files in add-to-library and classify workflows.
• low-complexity filtering in build workflow as default with --mask-prob 0.9.
