Function

Search a sequence database with 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:
hmmsearch [options] hmmfile seqfile outfile

The outfile parameter is new to EMBASSY HMMER.

hmmsearch reads an HMM from and searches for signifcantly similar sequence matches. seqfile will be looked for first in the current working directory, then in a directory named by the environment variable BLASTDB. This lets users use existing BLAST databases, if BLAST has been confgured for the site. hmmsearch may take minutes or even hours to run, depending on the size of the sequence database. The output is written to a file called . The output consists of four sections: a ranked list of the best scoring sequences, a ranked list of the best scoring domains, alignments for all the best scoring domains, and a histogram of the scores. A sequencescore may be higher than a domain score for the same sequence if there is more than one domain in the sequence; the sequence score takes into account all the domains. All sequences scoring above the -E and -T cutoffs are shown in the frst list, then every domain found in this list is shown in the second list of domain hits. If desired, E-value and bit score thresholds may also be applied to the domain list using the -domE and -domT options.

Algorithm

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

Usage

Here is a sample session with ehmmsearch

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).

Search a sequence database with a profile HMM Version: EMBOSS:6.2.0 Standard (Mandatory) qualifiers: [-hmmfile] infile File of HMMs. [-seqfile] seqall File of input sequences. -a integer [100] Limits the alignment output to the best scoring domains. -A0 shuts off the alignment output and can be used to reduce the size of output files. (Any integer value) [-outfile] outfile [*.ehmmsearch] The output consists of four sections: a ranked list of the best scoring sequences, a ranked list of the best scoring domains, alignments for all the best scoring domains, and a histogram of the scores. A sequence score may be higher than a domain score for the same sequence if there is more than one domain in the sequence; the sequence score takes into account all the domains. All sequences scoring above the -E and -T cutoffs are shown in the frst list, then every domain found in this list is shown in the second list of domain hits. If desired, E-value and bit score thresholds may also be applied to the domain list using the -domE and -domT options. Additional (Optional) qualifiers: -e float [10.] Set the E-value cutoff for the per-sequence ranked hit list to , where is a positive real number. The default is 10.0. Hits with E-values better than (less than) this threshold will be shown. (Any numeric value) -t float [-1000000.] Set the bit score cutoff for the per-sequence ranked hit list to , where is a real number. The default is negative infinity; by default, the threshold is controlled by E-value and not by bit score. Hits with bit scores better than (greater than) this threshold will be shown. (Any numeric value) Advanced (Unprompted) qualifiers: -z integer [0] Calculate the E-value scores as if we had seen a sequence database of sequences. The default is the number of sequences seen in your database file . (Any integer value) -compat boolean [N] Use the output format of HMMER 2.1.1, the 1998-2001 public release; provided so 2.1.1 parsers don't have to be rewritten. -cpu integer [0] Sets the maximum number of CPUs that the program will run on. The default is to use all CPUs in the machine. Overrides the HMMER NCPU environment variable. Only affects threaded versions of HMMER (the default on most systems). (Any integer value) -cutga boolean [N] Use Pfam GA (gathering threshold) score cutoffs. Equivalent to -globT -domT , but the GA1 and GA2 cutoffs are read from each HMM in the input HMM database individually. hmmbuild puts these cutoffs there if the alignment file was annotated in a Pfam-friendly alignment format (extended SELEX or Stockholm format) and the optional GA annotation line was present. If these cutoffs are not set in the HMM file, -cut ga doesn't work. -cuttc boolean [N] Use Pfam TC (trusted cutoff) score cutoffs. Equivalent to -globT -domT , but the TC1 and TC2 cutoffs are read from each HMM in hmmfile individually. hmmbuild puts these cutoffs there if the alignment file was annotated in a Pfam-friendly alignment format (extended SELEX or Stockholm format) and the optional TC annotation line was present. If these cutoffs are not set in the HMM file, -cut tc doesn't work. -cutnc boolean [N] Use Pfam NC (noise cutoff) score cutoffs. Equivalent to -globT -domT , but the NC1 and NC2 cutoffs are read from each HMM in hmmfile individually. hmmbuild puts these cutoffs there if the alignment file was annotated in a Pfam-friendly alignment format (extended SELEX or Stockholm format) and the optional NC annotation line was present. If these cutoffs are not set in the HMM file, -cut nc doesn't work. -dome float [1000000.] Set the E-value cutoff for the per-domain ranked hit list to , where is a positive real number. The default is infinity; by default, all domains in the sequences that passed the frst threshold will be reported in the second list, so that the number of domains reported in the per-sequence list is consistent with the number that appear in the per-domain list. (Any numeric value) -domt float [-1000000.] Set the bit score cutoff for the per-domain ranked hit list to , where is a real number. The default is negative infinity; by default, all domains in the sequences that passed the frst threshold will be reported in the second list, so that the number of domains reported in the per-sequence list is consistent with the number that appear in the per-domain list. Important note: only one domain in a sequence is absolutely controlled by this parameter, or by -domT. The second and subsequent domains in a sequence have a de facto bit score threshold of 0 because of the details of how HMMER works. HMMER requires at least one pass through the main model per sequence; to do more than one pass (more than one domain) the multidomain alignment must have a better score than the single domain alignment, and hence the extra domains must contribute positive score. See the Users' Guide for more detail. (Any numeric value) -forward boolean [N] Use the Forward algorithm instead of the Viterbi algorithm to determine the per-sequence scores. Per-domain scores are still determined by the Viterbi algorithm. Some have argued that Forward is a more sensitive algorithm for detecting remote sequence homologues; my experiments with HMMER have not confrmed this, however. -nulltwo boolean [N] Turn off the post hoc second null model. By default, each alignment is rescored by a postprocessing step that takes into account possible biased composition in either the HMM or the target sequence. This is almost essential in database searches, especially with local alignment models. There is a very small chance that this postprocessing might remove real matches, and in these cases --null2 may improve sensitivity at the expense of reducing specifcity by letting biased composition hits through. -pvm boolean [N] Run on a Parallel Virtual Machine (PVM). The PVM must already be running. The client program hmmpfam-pvm must be installed on all the PVM nodes. The HMM database hmmfile and an associated GSI index file hmmfile.gsi must also be installed on all the PVM nodes. (The GSI index is produced by the program hmmindex.) Because the PVM implementation is I/O bound, it is highly recommended that each node have a local copy of hmmfile rather than NFS mounting a shared copy. Optional PVM support must have been compiled into HMMER for -pvm to function. -xnu boolean [N] Turn on XNU filtering of target protein sequences. Has no effect on nucleic acid sequences. In trial experiments, -xnu appears to perform less well than the default post hoc null2 model. Associated qualifiers: "-seqfile" associated qualifiers -sbegin2 integer Start of each sequence to be used -send2 integer End of each sequence to be used -sreverse2 boolean Reverse (if DNA) -sask2 boolean Ask for begin/end/reverse -snucleotide2 boolean Sequence is nucleotide -sprotein2 boolean Sequence is protein -slower2 boolean Make lower case -supper2 boolean Make upper case -sformat2 string Input sequence format -sdbname2 string Database name -sid2 string Entryname -ufo2 string UFO features -fformat2 string Features format -fopenfile2 string Features file name "-outfile" associated qualifiers -odirectory3 string Output directory General qualifiers: -auto boolean Turn off prompts -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 -debug boolean Write debug output to program.dbg -verbose boolean Report some/full command line options -help boolean Report command line options and exit. More information on associated and general qualifiers can be found with -help -verbose -warning boolean Report warnings -error boolean Report errors -fatal boolean Report fatal errors -die boolean Report dying program messages -version boolean Report version number and exit

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.

ehmmsearch 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.

The following additional options are provided:

-outfile   : Multiple sequence alignment output file.

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

The user must provide the full filename of a sequence database for the sequence input ("seqfile" ACD option), not an indirect reference, e.g. a USA is NOT acceptable. This is because hmmsearch (which ehmmsearch wraps) does not support USAs, and a full sequence database is too big to write to a temporary file that the original hmmsearch would understand.

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)
