   while ($readline = <$CFILE>) {
       chomp $readline;
       my ($key , $value) = (split /::/, $readline);
       $data_ids($key) = $value;
       $readline = <$CFILE>;
   }
    
   foreach my $key (keys %data_ids) {
       $cChipid = $data_ids('chipid');
       $cSubVersId = $data_ids('subversid');
