I have worked with Text::CSV in the past. I have only slight issue with it, which I am not sure if I am not getting how to use it correctly. Here is the following code: 

my $csv = Text::CSV->new();

open (CSV,"<", "Merged_CSVfiles.csv") || die "File not found\n"; 

    while (<CSV>) {            # While Loop Open Bracket

        next if ($. == 1);
        
        if ($csv->parse($_)) {        #If Open Bracket
        
            my @columns = $csv->fields();
                
                #__ Assigning $columns[0]-$columns[26] to variables
                

                    
                    my @Sample_Ids_m = $columns[16];
                    print ($Sample_Ids_m[0]);        
                    
    
        } else {                    # If Closed Bracket
                                            # Else Open Bracket
        
            my $err = $csv-> error_input; 
            print "Failed to parse line: $err";
            
            close CSV;

        } # Closed Else Bracket
    }#Closed While Loop Bracket

All the ID are loaded into the first element of the array @Sample_Ids_m. This would be a problem but arrays can be different lengths and there are no rules current for constructing Sample ID numbers. It is a random sort of thing.

If there was some uniformity I could use the substr function and a for loop and extract our individual id's but I dont seem to be able too. I will play around with it for a bit more
