## Function

Align sequences to an HMM profile

## Description

EMBASSY HMMER is a suite of application wrappers to the original hmmer v2.3.2 applications written by Sean Eddy. hmmer v2.3.2 must be installed on the same system as EMBOSS and the location of the hmmer executables must be defined in your path for EMBASSY HMMER to work.

Usage:
ehmmalign [options] hmmfile seqfile outfile

The outfile parameter is new to EMBASSY HMMER. The multiple sequence alignment is always written to outfile. The name of outfile is specified by the -o option as normal.

hmmalign reads an HMM profile <hmmfile> and a set of sequences <seqfile>, aligns the sequences to the profile HMM, and outputs a multiple sequence alignment <outfile>. The set of sequences may be unaligned or aligned. If it is aligned, the existing alignment is ignored and hmmalign will align them the way it wants.

## Algorithm

Please read the Userguide.pdf distributed with the original HMMER and included in the EMBASSY HMMER distribution under the DOCS directory.

## Usage

## Command line arguments

Where possible, the same command-line qualifier names and parameter order is used as in the original hmmer. There are however several unavoidable differences and these are clearly documented in the "Notes" section below.

More or less all options documented as "expert" in the original hmmer user guide are given in ACD as "advanced" options (-options must be specified on the command-line in order to be prompted for a value for them).

       Standard (Mandatory) qualifiers:
      [-hmmfile]           infile     File containing a HMM profile
      [-seqfile]           seqset     File containing a (set of) sequence(s)
      [-o]                 align      [*.ehmmalign] Multiple sequence alignment
                                      output file.

       Additional (Optional) qualifiers:
       -m                  boolean    [N] Include in the alignment only those
                                      symbols aligned to match states. Do not show
                                      symbols assigned to insert states.
       -q                  boolean    [N] Quiet; suppress all output except the
                                      alignment itself. Useful for piping or
                                      redirecting the output.

       Advanced (Unprompted) qualifiers:
       -mapali             infile     Reads an alignment from file and aligns it
                                      as a single object to the HMM; e.g. the
                                      alignment in file is held fixed. This allows
                                      you to align sequences to a model with
                                      hmmalign and view them in the context of an
                                      existing trusted multiple alignment. The
                                      alignment to the alignment is defined by a
                                      'map' kept in the HMM, and so is fast and
                                      guaranteed to be consistent with the way the
                                      HMM was constructed from the alignment. The
                                      alignment in the file must be exactly the
                                      alignment that the HMM was built from.
                                      Compare the -withali option.
       -withali            infile     Reads an alignment from file and aligns it
                                      as a single object to the HMM; e.g. the
                                      alignment in file is held fixed. This allows
                                      you to align sequences to a model with
                                      hmmalign and view them in the context of an
                                      existing trusted multiple alignment. The
                                      alignment to the alignment is done with a
                                      heuristic (nonoptimal) dynamic programming
                                      procedure, which may be somewhat slow and is
                                      not guaranteed to be completely consistent
                                      with the way the HMM was constructed (though
                                      it should be quite close). However, any
                                      alignment can be used, not just the
                                      alignment that the HMM was built from.
                                      Compare the -mapali option.

-mapali

Reads an alignment from file and aligns it as a single object to the HMM; e.g. the alignment in file is held fixed. This allows you to align sequences to a model with hmmalign and view them in the context of an existing trusted multiple alignment. The alignment to the alignment is defined by a 'map' kept in the HMM, and so is fast and guaranteed to be consistent with the way the HMM was constructed from the alignment. The alignment in the file must be exactly the alignment that the HMM was built from. Compare the -withali option.

## Input file format

### Alignment and sequence formats

Input and output of alignments and sequences is limited to the formats that the original hmmer supports. These include stockholm, SELEX, MSF, Clustal, Phylip and A2M /aligned FASTA (alignments) and FASTA, GENBANK, EMBL, GCG, PIR (sequences). It would be fairly straightforward to adapt the code to support all EMBOSS-supported formats.

### Compressed input files

Automatic processing of gzipped files is not supported.

ehmmalign reads any normal sequence USAs.

### Input files for usage example

## Notes

### 1. Command-line arguments

The following original HMMER options are not supported:

    -h         : Use -help to get help information instead.
    -informat  : All common sequence file formats are supported automatically.
    -oneline   : Alignment format output is specified via the ACD file and /
                 or the -aformat command line qualifier.
    -outformat : Alignment format output is specified via the ACD file and / or
                 the -aformat command line qualifier.

### 2. Installing EMBASSY HMMER

The EMBASSY HMMER package contains "wrapper" applications providing an EMBOSS-style interface to the applications in the original HMMER package version 2.3.2 developed by Sean Eddy. Please read the file INSTALL in the EMBASSY HMMER package distribution for installation instructions.

### 3. Installing original HMMER

To use EMBASSY HMMER, you will first need to download and install the original HMMER package. Please read the file 00README in the the original HMMER package distribution for installation instructions:

    WWW home:       http://hmmer.wustl.edu/
    Distribution:   ftp://ftp.genetics.wustl.edu/pub/eddy/hmmer/

### 4. Setting up HMMER

For the EMBASSY HMMER package to work, the directory containing the original HMMER executables *must* be in your path. For example if you executables were installed to "/usr/local/hmmer/bin", then type:

    set path=(/usr/local/hmmer/bin/ $path)
    rehash

### 5. Getting help

Please read the Userguide.pdf distributed with the original HMMER and included in the EMBASSY HMMER distribution under the DOCS directory. The first 3 chapters (Introduction, Installation and Tutorial) are particularly useful.

Please read the 'Notes' section below for a description of the differences between the original and EMBASSY HMMER, particularly which application command line options are supported.

## References

None.

## Warnings

### Types of input data

hmmer v3.2.1 and therefore EMBASSY HMMER is only recommended for use with protein sequences. If you provide a non-protein sequence you will be reprompted for a protein sequence. To accept nucleic acid sequences you must replace instances of < type: "protein" > in the application ACD files with <type: "nucleic" >.

### Environment variables

The original hmmer uses BLAST environment variables (below), if defined, to locate files. The EMBASSY HMMER does not.

    BLASTDB   location of sequence databases to be searched
    BLASMAT   location of substitution matrices
    HMMERDB   location of HMMs

### Sequence input

ehmmalign makes a temporary local copy of its input sequence data. You must ensure there is sufficient disk space for this in the directory that ehmmalign is run.

## Diagnostic Error Messages

None.

## Exit status

It always exits with status 0.

## Known bugs

None.

## Author(s)

This program is an EMBOSS conversion of a program written by Sean Eddy as part of his HMMER package.

Although we take every care to ensure that the results of the EMBOSS version are identical to those from the original package, we recommend that you check your inputs give the same results in both versions before publication.

Please report all bugs in the EMBOSS version to the EMBOSS bug team, not to the original author. Jon Ison (jison © rfcgr.mrc.ac.uk)

This program is an EMBASSY wrapper to a program written by Sean Eddy as part of his hmmer package.

Please report any bugs to the EMBOSS bug team in the first instance, not to Sean Eddy.
