work

Usage    - IntActParser->work()
Returns  - A new OBO ontology with new proteins and interactions from IntAct

Returns  - found result or undefined if not found

NAME

OBO::CCO::IntActParser - An IntAct to OBO parser/filter.

SYNOPSIS

use OBO::CCO::IntActParser; use strict;

my $A_t_intact_files_dir = "/home/pik/Bioinformatics/Erick_two/IntactFiles/At/"; my @A_t_intact_files = @{&get_intact_files ($A_t_intact_files_dir)};

my $A_t_interactionmanager = InteractionManager->new; $A_t_interactionmanager->work( "pre_cco_A_thaliana.obo", "cco_I_A_thaliana.obo", "3702", "cco_i_A_thaliana.ids", "cco_b_A_thaliana.ids", "cco_i.ids", "cco_b.ids", @A_t_intact_files );

sub get_intact_files{ my $intact_files_dir = shift; my @intact_files = (); opendir(DIR, $intact_files_dir) || die "can't opendir $intact_files_dir: $!"; my @files = readdir(DIR); for my $file (@files){ if (!($file eq ".") and !($file eq "..")){ push (@intact_files,$intact_files_dir.$file); } } closedir DIR; return \@intact_files; }

DESCRIPTION

A parser for IntAct to OBO conversion. The conversion is filtered according to the proteins already existing in the OBO file and the roles this proteins have in the interactions (prey, bait, neutral component). It deletes any interaction in OBO that it is not present in IntAct, for sync.
