my $it = $sam_reader->iterator();

# Iterate on lines and explore CRAC special fields of SAM
while(my $line = $it->()) {
  if(defined $line->events('Junction') && $line->isClassified('normal')) {
    my @junctions = @{$line->events('Junction')};
    foreach my $junction (@junctions) {
      print "Foud Junction : [type : $junction->{type}, loc : $junction->{loc}, gap : $junction->{gap}]\n";
