thanks for all the suggestions, and yes the output should look like the output that anonymous monk posted above.
I can read the file into an array, but I wasn't sure how to
proceed through the array to average columns 6 and 7.
#!/usr/bin/perl
use strict;
use warnings;
use Getopt::Long;
my $infile;
my @fields;
my $i;
my $j;
GetOptions (
"infile=s" => \$infile,
);
open INFILE, "<$infile" or die $!;
#open RES, ">result.txt" or die $!;
while (<INFILE>){
@fields = split(/\t+/, $_);
my ($name, $chr, $location, $gen, $dom, $pval, $fst) = @fields
+[0..6];
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
