NAME
metastudent - predictor of gene ontology terms from protein sequence
SYNOPSIS
metastudent -i FASTA_FILE -o RESULT_FILE_PREFIX [--debug] [--keep-temp]
[--silent] [--output-blast] [--blast-only] [--all-predictions]
[--ontologies=MFO or BPO or MFO,BPO]
[--blast-kickstart-databases=BLAST_RESULT_FILE(S)] [--temp-dir=DIR]
[--config=CONFIG_FILE] !!! Make sure your fasta file contains at most
500 sequences !!!
DESCRIPTION
Metastudent predicts Gene Ontology (GO) terms from the Molecular
Function Ontology (MFO) and Biological Process Ontology (BPO) for input
protein sequences by homology-based inference from already annotated
proteins.
Large (1 GB in total) data files necessary for the operation of
metastudent are downloaded automatically on the first use of the
program. The download is restartable. You can also make an explicit
call to
metastudentdata (by default /usr/bin/metastudentdata) to
download the data files. In case the data directory (by default
/usr/share/metastudent-data) is not writable and you are not root, the
operation is
reattempted with sudo(8).
Output format
For each selected ontology (see --ontologies), one output file is
produced (see -o). Each line in each file associates a protein with a
GO term and a reliability for the association (0.0 to 1.0). The
following format is used: <PROTEIN ID><TAB><GO_TERM><TAB><RELIABILITY>

OPTIONS
-i FASTA_FILE
The input fasta file. Please try to remove any special formattings
(e.g. whitespaces) in the sequences before using them as input. Due
to high memory usage, make sure your fasta file contains at most
500 sequences.
-o RESULT_FILE_PREFIX
The file name prefix of the output files. GO terms are organized in
ontologies. Metatstudent treats each ontology differently and
outputs one result file for each. For example, if
<RESULT_FILE>=./myresult and MFO (Molecular Function Ontology) and
BPO (Biological Process Ontology) ontologies are selected (see
option --ontologies), then metastudent creates two output files:
./myresult.MFO.txt and ./myresult.BPO.txt.
--debug
Print extra debugging messages.
--keep-temp
Whether to keep the temp directories after metastudent has finished
(they can be useful when errors occur or in combination with
--blast-kickstart-databases).
--silent
No progress messages (stdout), only errors (stderr).
--output-blast
Whether to output the result of the BLAST runs. Useful in
combination with --blast-kickstart-databases. Output file name
format is RESULT_FILE_PREFIX.<BLAST_OPTIONS>.blast.
--blast-only
Whether to only output the result of the BLAST runs, and nothing
else. See options --output-blast and --blast-kickstart-databases.
--all-predictions
Whether to output the prediction results of the individual
predictors. File name format of the output file is
<RESULT_FILE_PREFIX>.<ONTOLOGY>.<METHOD>.txt.
--no-names
Whether to exclude the actual GO term names as a column in the
output prediction file(s).
--with-images
Whether to also generate an image that displays the predicted GO
terms as a GO graph. This option can only be used with exactly one
input sequence and only when connected to the internet.
--ontologies=MFO or BPO or MFO,BPO
A comma separated list of ontologies to create predictions for.
Default is MFO,BPO. If used in combination with
--blast-kickstart-databases, the number and order of the ontologies
must correspond to the kickstart files.
--blast-kickstart-databases=<BLAST_RESULT_FILES>
Since running BLAST is usually the part that takes the longest in
metastudent, this option allows you to re-use the output of a
previous run. This is useful to test, for example, different
parameters or when you have lost a prediction. The number of
kickstart files must correspond to the number of ontologies (see
option --ontologies). Separate the file paths with commas. For
example:
--blast-kickstart-databases=<RESULT_FILE_MFO>,<RESULT_FILE_BPO>
(kickstart for both ontologies) or
--blast-kickstart-databases=,<RESULT_FILE_BPO> (only kickstart BPO;
note the comma).
--temp-dir=DIR
The parent temp directory to use instead of the one specified with
tmpDir in the metastudent configuration file.
--config=FILE
The path to a custom metastudent configuration file; overrides all
settings of the configuration files found in the FILES section of
this man page.
FILES
<package_data_dir>/metastudentrc.default
The metastudent configuration file.
<sysconfdir>/metastudentrc
The metastudent configuration file, overrides
<package_data_dir>/metastudentrc.default.
<homedir>/.metastudentrc
The metastudent configuration file, overrides
<sysconfdir>/metastudentrc.
EXAMPLES
The example test.fasta file can be found in <package_doc_dir>/examples
(usually /usr/share/doc/metastudent/examples).
Predict the GO terms for the sequences in test.fasta for both the MFO
and the BPO ontology:
metastudent -i test.fasta -o test.result
Create the BLAST output to predict the MFO terms for sequences in
test.fasta (not the actual predictions, yet; see next example).
metastudent -i test.fasta -o test.result --blast-only --output-blast --ontologies=MFO
Predict the MFO and BPO terms for sequences in test.fasta with a
precomputed MFO BLAST output (see previous example; note the comma at
the end).
metastudent -i test.fasta -o test.result --ontologies=MFO,BPO --blast-kickstart-databases=test.result_eval0.001_iters3_srcexp.mfo.blast,
