=head1 NAME
Bio::EnsEMBL::Analysis::RunnableDB::BlastRfam
=head1 SYNOPSIS
my $blast = Bio::EnsEMBL::Analysis::RunnableDB::BlastmiRNA->new
(
-analysis => $analysis,
-db => $db,
-input_id => 'contig::AL1347153.1.3517:1:3571:1'
);
$blast->fetch_input;
$blast->run;
my @output =@{$blast->output};
=head1 DESCRIPTION
Modified blast runnable for specific use with miRNA
Use for running BLASTN of genomic sequence vs miRNAs prior to
miRNA anaysis
Slice size seems best around 200k
