Unfortunately, what you've shown so far is not coherent information. E.g., 
my @data = [1,5,7,8,9,10,11,3,3,5,5,5,7,2,2];

isn't particularly useful since you're assigning a scalar list reference to an array (meaning that you'll always end up with a single-element array.) Something like this would make more sense: 
my $data = [1,5,7,8,9,10,11,3,3,5,5,5,7,2,2];

I'm going to make some assumptions here about what you're trying to do; please feel free to correct any false ones. If you're trying to read a file that is composed of lines with comma-separated values, and where each line should be read in as a list reference of the above type, then something like this should be useful: 
use strict;

open my $fh, '<', 'file' or die "file: $!\n";

my @data;
while (<$fh>){
    chomp;
    push @data, [split /,/];
}

Each of the elements of @data will be a reference to a list containing the values on each line.
