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.

work

Usage    - IntActParser->work()
Returns  - A new OBO ontology with new proteins and interactions from IntAct
Args     - old OBO file, new OBO file, taxon (e.g. 3702), cco_i_taxon_ids file, cco_b_taxon_ids file, cco_i_ids file, cco_b_ids file, XML file 1, XML file 2, ...
Function - Adds or deletes interactions to/from an OBO file, filtering the interactions from Intact XML files according to proteins already existing in CCO and their roles in IntAct (bait, prey, neutral component). It also includes any new proteins needed. It should be used for each taxon.
