Bio::EnsEMBL::Compara::RunnableDB::HealthCheck
=cut
=head1 SYNOPSIS
$module->fetch_input
$module->run
$module->write_output
=cut
=head1 DESCRIPTION
This module is inteded to run automatic checks at the end of a pipeline (or at any other time)
=head1 OPTIONS
This module has been designed to run one test per analysis_job. All the options are specific to
the test iself and therefore you shouldn't set any parameters in the analysis table. Use the input_id
column of the analysis_job to set these values.
=head2 test
The name of the test to be run. See below for a list of tests
=head2 params
Parameters used by the test
=head1 TESTS
=head2 conservation_jobs
This test checks that there are one conservation analysis per alignment.
Parameters:
=over
=item logic_name
Logic name for the Conservation analysis. Default: Gerp
=item method_link_type (or from_method_link_type)
method_link_type for the multiple alignments. Default: PECAN
=back
=head2 conservation_scores
This test checks whether there are conservation scores in the table, whether
these correspond to existing genomic_align_blocks, whether the
right gerp_XXX entry exists in the meta table and whether there
are no alignments wiht more than 3 seqs and no scores.
Parameters:
=over
=item method_link_species_set_id (or mlss_id)
Specify the method_link_species_set_id for the conservation scores. Note that this can
be guessed from the database altough specifying the right mlss_id is probably safer.
For instance, it may happen that you expect 2 or 3 sets of scores. In that case it is
recommended to create one test for each of these set. If one of the sets is missing,
the test will succeed as it will successfully guess the mlss_id for the other sets and
check those values only.
=back
=head1 EXAMPLES
Here are some input_id examples:
=over
=item {test=>'conservation_jobs'}
Run the conservation_jobs test. Default parameters
=item {test=>'conservation_jobs', params=>{logic_name=>'Gerp', method_link_type=>'PECAN'}}
Run the conservation_jobs test. Specify logic_name for the Conservation analysis and method_link_type
for the underlying multiple alignments
=item {test=>'conservation_scores'}
Run the conservation_scores test. Default parameters
=item {test=>'conservation_scores', params=>{mlss_id=>50002}}
Run the conservation_scores test. Specify the method_link_species_set_id for the conservation scores
