hhsuite - 3.3.0+ds-8+b3 main

HH-suite is an open-source software package for sensitive protein sequence
searching based on the pairwise alignment of hidden Markov models (HMMs).
.
This package contains HHsearch and HHblits among other programs and utilities.
.
HHsearch takes as input a multiple sequence alignment (MSA) or profile HMM
and searches a database of HMMs (e.g. PDB, Pfam, or InterPro) for homologous
proteins. HHsearch is often used for protein structure prediction to detect
homologous templates and to build highly accurate query-template pairwise
alignments for homology modeling.
.
HHblits can build high-quality MSAs starting from single sequences or from
MSAs. It transforms these into a query HMM and, using an iterative search
strategy, adds significantly similar sequences from the previous search to
the updated query HMM for the next search iteration. Compared to PSI-BLAST,
HHblits is faster, up to twice as sensitive and produces more accurate
alignments.
