Archive of stable representatives of the HMMER1 and HMMER2 lineages

The 1992-1998 HMMER1 lineage was closer to the original Krogh/Haussler conception of profile HMMs. It includes a feature that is missing in HMMER2 and HMMER3: the hmmt program for training HMMs from initially unaligned sequences (and hence creating multiple alignments). The final stable release of HMMER1 was 1.8.5 (Feb 2006). The 1998-2003 HMMER2 lineage introduced the "Plan 7" profile HMM architecture (which HMMER3 still largely shares), and was the long-time foundation for Pfam and other protein domain databases. It still included glocal and global alignment modes that HMMER3 lacks, because HMMER3 currently implements only fully local/local alignment; HMMER2 lacks DNA-DNA comparison that was present in HMMER1, and has returned in HMMER3.1. The final stable release of HMMER2 was 2.3.2 (Oct 2003).
