# hmm2fetch(1)

## NAME

- hmm2fetch - retrieve an HMM from an HMM database

  ## SYNOPSIS

**hmm2fetch** *\[options\]* *database* *name*

## DESCRIPTION

**hmm2fetch** is a small utility that retrieves an HMM called *name* from a HMMER model database called *database.* in a new format,  and prints that model to standard output. For example, *hmm2fetch Pfam rrm* retrieves the RRM (RNA recognition motif) model from Pfam, if the environment variable HMMERDB is set to the location of the Pfam database. The retrieved HMM file is written in HMMER 2 ASCII format.

The database must have an associated GSI index file. To index an HMM database, use the program **hmm2index.**

## OPTIONS

- **-h**

  Print brief help; includes version number and summary of all options, including expert options.

- **-n**

  Interpret *name* as an HMM number instead of a name. Numbering starts at 0. For example, to fetch the first HMM from an HMM database called **foo,** you would do  **hmm2fetch -n 0 foo.**
