HMMER can be used to search sequence databases with single query sequences +but it becomes particularly powerful when the query is an multiple sequence alignment of a sequence family. +HMMER makes a profile of the query that assigns a position-specific scoring system for substitutions, +insertions, and deletions. HMMER profiles are probabilistic models called "profile hidden Markov models" +(profile HMMs) (Krogh et al., 1994; Eddy, 1998; Durbin et al., 1998). + +Compared to BLAST, FASTA, and other sequence alignment and database search tools based on older +scoring methodology, HMMER aims to be significantly more accurate and more able to detect remote +homologs, because of the strength of its underlying probability models. In the past, this strength came +at a significant computational cost, with profile HMM implementations running about 100x slower than +comparable BLAST searches. With HMMER3, HMMER is now essentially as fast as BLAST. + +The programs in HMMER:: + + Single sequence queries: new to HMMER3:: + + phmmer Search a sequence against a sequence database.
