MMseqs2 Release 14-7e284

This is a major release containing features implemented for ColabFold, Foldseek, MMseqs2 profile-profile (not published yet, and still in preview) and many bugfixes. Thanks a lot to the contributors who submitted bug fixes.

If you are using the Docker Hub based MMseqs2 containers, please switch to the new Github Container Registry based ones. The Docker Hub containers will not be maintained in the future.

Breaking

• Profile databases created by previous MMseqs2 releases won't work anymore with this release. Please recreate them from previous search results or MSAs with result2profile or `msa2profile.
• Profile k-mer threshold parameter were fitted to new pseudo-counter parameter (--pca,--pcb). Previous --k-score parameters will have differing sensitivity. However, most users will have set -s instead, which was fitted to match as closely as possible.

Features

• gff2db now should actually work correctly after refactoring (488df86, thanks @RuoshiZhang)
• result2msa now supports reading from precomputed index
• Add db2tar: Create a tar file from a database
• Add parsable columnar tsv output to databases with --tsv
• Add taxonomic filtering during prefilter with --taxon-list
• Add --comp-bias-corr-scale to adjust the weight of the compositional bias correction
• Add --mask-prob parameter to adjust tantan's masking threshold
• Add context specific pseudo-counts to result2profile
• Add iterative profile-profile search workflow (thanks @haydenji0731)
• Add support for profile-profile scoring in striped Smith-Waterman algorithm (thanks @haydenji0731)
• Add support for gap-open/gap-close costs to striped Smith-Waterman algorithm (thanks @hgsommer)
• Add environment variable MMSEQS_IGNORE_INDEX to ignore an existing precomputed index
• createsubdb and view can now return results from identifiers in .lookup with --id-mode 1
• Change compressdb loop to omp static to keep order
• Improvements to nucleotide alignments and scoring (thanks @AnnSeidel)

Features built for ColabFold now available in MMseqs2

• Add pairaln: taxonomic pairing on sequences for MSA building (9a0df0d, 5e245d1, 3f8695e, 3e92abf, edb8223, e19df7c)
• Add A3M support to result2msa (--msa-format-mode 5)
• Add A3M support with alignment information to result2msa (--msa-format-mode 6)
• result2profile allows --diff 0
• Make taxonomy mapping mmap'able for (near) instant read-in
• Add workflow to create expandable profile (profile-profile) db from TSVs tsv2exprofiledb
• Enable result2profile/filterresult to read new expand alignment index
• Add support to filter MSAs in buckets filterresult, result2profile
• Add --filter-min-enable to enable filtering only above a minimum threshold of hits (c6d8ae0)
• Expand can filter in each target cluster before expanding (75af0c8, 85ce847)

MMseqs2 databases

• Added VOGDB
• Updated dbCAN2 to V9 and removed .aln suffix from profile names
