I wrote a program to order some output I had from another file. (Tab delimited; first column is the file name; I'm looking for certain letters in the file name). WHen I run this code, I get an error saying 'No comman allowed after file handle, line 42'. The line in question will be marked.

I don't understand it, because $i_file opens normally, and the only difference between $i_ and $o_file is the '>'. I don't even know what comma it's talking about!

#!/usr/bin/perl

use warnings;
use strict;

my $i_file = "faster_averages.txt";
my $o_file = ">ordered_averages.txt";
my @i;
my $j = 0;
my @CCFN;
my @CCFN_NT;
my @EBG;
my @EBGFN;
my @PR;
my @PRFN;
my @BL;
my @BLSTDG;
my @BLSTDGG;
my @output;

open(IN, $i_file) or die "$i_file failed to open: $!";
my @lines = <IN>;
close IN;

for my $file ((split /\t/, @lines)[0]) {
  if($file =~ /CCFN\d+NT/) { $CCFN_NT[$i[0]++] = $lines[$j] }
  if($file =~ /CCFN/)      { $CCFN[$i[1]++]    = $lines[$j] }
  if($file =~ /EBGFN/)     { $EBGFN[$i[2]++]   = $lines[$j] }
  if($file =~ /EBG/)       { $EBG[$i[3]++]     = $lines[$j] }
  if($file =~ /PRFN/)      { $PRFN[$i[4]++]    = $lines[$j] }
  if($file =~ /PR/)        { $PR[$i[5]++]      = $lines[$j] }
  if($file =~ /BLSTDGG/)   { $BLSTDGG[$i[6]++] = $lines[$j] }
  if($file =~ /BLSTDG/)    { $BLSTDG[$i[7]++]  = $lines[$j] }
  if($file =~ /BL/)        { $BL[$i[8]++]      = $lines[$j] }

  $j++;
}

@output = (@CCFN,@CCFN_NT,@EBG,@EBGFN,@PR,@PRFN,@BL,@BLSTDG,@BLSTDGG);

# Right here
open(OUT, $o_file) or die "$o_file failed to be created: $!";
# $o_file defined above

print OUT, @output;
