Hi JohnGG,

I tried running the script but this error kept popping up! Note that I modified it to take files:

 my $FILENAME1 = "random.txt"; 
open(INFILE1, $FILENAME1);
 
 my @tests =
    map [ split ],
    <INFILE1>;
 
 my $FILENAME2 = "my_column_file.txt"; 
open(INFILE2, $FILENAME2);
 
 my @results;
 while ( <INFILE2> )
 {
     my @cols = split;
     foreach my $idx ( 0 .. $#tests )
     {
         foreach my $subidx ( 0 .. $#{ $tests[ $idx ] } )
         {
             my @posns = split m{}, $tests[ $idx ]-[ $subidx ];
             $results[ $idx ]-[ $subidx ] ++
                if scalar @posns == grep { q{r} eq $cols[ $_ ] } @posn
+s;
         }
     }
 }
 
 say qq{@$_} for @results;

the error was:

Can't modify anonymous list ([]) in postincrement (++) at gg.pl line 2
+0, near "] ++"
syntax error at gg.pl line 26, near "say qq{@$_}"
Execution of Jgg.pl aborted due to compilation errors.

Line 26 is this one: $results $idx - $subidx ++. Also I notice an error/flag in the last line. Should i change the say to print?
