Hi, supriyoch_2008,

  • Please you may use strict in your script.
  • Replace these lines in inv2.pl:
    ## Input the matrix text file: print "\n\n Please type the filename(.txt) i.e. d1.txt: "; $DNAfilename = <STDIN>; chomp $DNAfilename; ## To remove white space: $DNAfilename=~ s/\s//gis; # open the file, or exit unless ( open(DNAFILE, $DNAfilename) ) { print "Cannot open file \"$DNAfilename\"\n\n"; exit; } # Line 10 @a = <DNAFILE>; @m2=@a;
    with these:
    my @m2; ## Input the matrix text file: print "\n\n Please type the filename(.txt) i.e. d1.txt: "; chomp( my $filename = <STDIN> ); open my $fh, '<', $filename or die "can't open file $!"; while (<$fh>) { push @m2, [ split /,/, $_ ]; } close $fh or die "can't close file: $!";
Note:
Ofcourse, your script(s) can be improved upon, but these should give you what you want to start with.
Hope it helps.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
