It seems to me that you are storing things in a reference to an array: 
[ ['measurement1',
   [ ['test subject number', 21, 27], ['value', 50], ... ],
  ...
  ],
...
]

But you are trying to get at the data as if it is a reference to a hash: 

$info->{subdirectory}->{file}->[measurement] = INDEX;
$info->{subdirectory}->{file} = PARSER;
$info->[measurement]->{name} = NAME;

But it is hard to tell given the examples you actually gave. Is $info a reference to an array or to a hash?

Also, you might find your code more readable if you only dereference where you need to do so. For instance, instead of $info->{subdirectory}->{file} try just $info->{subdirectory}{file}.

By the way, an "ADT" usually means an "Abstract Data Type" not an "Advanced Data Type." One person's advanced data type is another's basic data type.

I'd be happy to help if you provide a little more information.
