Module location of self-written perl module : I am trying to use my module in a script. 
I know that you have to provide a module location and would like to provide the path in the script. However, I get the error message: 
No such file or directory 

this is my script: 

    use strict;
    use warnings;
    use lib "C:/Users/XPS13/Documents/Uni/UEProgramming";
    use Bioinformatics;

    my $DNAinput = "restriction_test.txt"; 
    open (my $FH_DNA_in, "<", $DNAinput) or die " Can't open file $DNAinput: $!\n";
    print "Pattern match for input file \n";
    print (Bioinformatics::Pattern($FH_DNA_in), "\n"); #  applying module function  

and this is my module 

    package Bioinformatics; # making module, 1st line contains name 
    use strict; # module uses strict and warnings 
    use warnings;

    sub Pattern {
    my $count = "0";
    my ($DNAinput) = @_;
    open (my $FH_DNA_in, "<", $DNAinput) or die " Can't open file $DNAinput: $!\n";
        while (my $line = <$FH_DNA_in>) {
            if ($line =~ /[AG]GATC[TC]/ ) { 
            ++ $count;
            }
    }
        print "Your sequence contains the pattern [AG]GATC[TC] $count times\n";
    }
        1; # last line
