Function

Generate sequences from a profile HMM

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:
ehmmemit [options] hmmfile outfile

The outfile parameter is new to EMBASSY HMMER. The synthetic sequences are always written to outfile. The name of outfile is specified by the -o option as normal.

hmmemit reads an HMM file from a file containing one or more HMMs, and generates a number of sequences from each HMM; or, if the -c option is selected, generate a single majority-rule consensus. This can be useful for various applications in which one needs a simulation of sequences consistent with a sequence family consensus. By default, hmmemit generates 10 sequences and outputs them in FASTA (unaligned) format file .

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). 

Generate sequences from a profile HMM.
Version: EMBOSS:6.2.0

   Standard (Mandatory) qualifiers (* if not always prompted):
  [-hmmfile]           infile     File containing one or more HMMs.
   -c                  boolean    [N] Predict a single majority-rule consensus
                                  sequence instead of sampling sequences from
                                  the HMM's probability distribution. Highly
                                  conserved residues (p >= 0.9 for DNA, p >=
                                  0.5 for protein) are shown in upper case;
                                  others are shown in lower case. Some insert
                                  states may become part of the majority rule
                                  consensus, because they are used in >= 50%
                                  of generated sequences; when this happens,
                                  insert-generated residues are simply shown
                                  as 'x'.
*  -nseq               integer    [10] Generate  sequences. Default is 10.
                                  (Any integer value)
  [-o]                 outfile    [*.ehmmemit] File of synthetic sequences.

   Additional (Optional) qualifiers:
   -a                  boolean    [N] Write the generated sequences in an
                                  aligned format (SELEX) rather than FASTA.
   -q                  boolean    [N] Quiet; suppress all output except for
                                  the sequences themselves. Useful for piping
                                  or directing the output.

   Advanced (Unprompted) qualifiers:
   -seed               integer    [0] Set the random seed to , where  is
                                  a positive integer. The default is to use
                                  time() to generate a different seed for each
                                  run, which means that two different runs of
                                  hmmemit on the same HMM will give slightly
                                  different results. You can use this option
                                  to generate reproducible results. (Integer 0
                                  or more)

   -stdout             boolean    Write first file to standard output
   -filter             boolean    Read first file from standard input, write
                                  first file to standard output
   -options            boolean    Prompt for standard and additional values

-c boolean Predict a single majority-rule consensus sequence instead of sampling sequences from the HMM's probability distribution. Highly conserved residues (p >= 0.9 for DNA, p >= 0.5 for protein) are shown in upper case; others are shown in lower case. Some insert states may become part of the majority rule consensus, because they are used in >= 50% of generated sequences; when this happens, insert-generated residues are simply shown as 'x'. Boolean value Yes/No No
-nseq integer Generate <n> sequences. Default is 10. Any integer value 10
[-o]
(Parameter 2)		 outfile File of synthetic sequences. Output file <*>.ehmmemit
Additional (Optional) qualifiers
-a boolean Write the generated sequences in an aligned format (SELEX) rather than FASTA. Boolean value Yes/No No
-q boolean Quiet; suppress all output except for the sequences themselves. Useful for piping or directing the output. Boolean value Yes/No No
Advanced (Unprompted) qualifiers
-seed integer Set the random seed to <n>, where <n> is a positive integer. The default is to use time() to generate a different seed for each run, which means that two different runs of hmmemit on the same HMM will give slightly different results.

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.

ehmmemit 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.
-n         : Use -nseq instead (-n causes problems for GUI developers)

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

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 © ebi.ac.uk)
