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 and a set of sequences , aligns the sequences to the profile HMM, and outputs a multiple sequence alignment . 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.

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). 

Align sequences to an HMM profile
Version: EMBOSS:6.4.0.0

   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. (default -aformat fasta)

   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.

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.

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 .

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.
