hi, I try to replace white spaces with tabs, but my string gets changed into a numeric value after that. I wrote the basic step as a new program to show what happens 

#!/usr/bin/perl -w
use strict;

$_ = "CC1G_00040T0    NODE_4204_length_20667_cov_33.873905_4    3e-46"
+;

my $line = $_;
print "$line\n";
$line = s/\s+/\t/g;
print "$line\n";

when I run this, it gives the following:

CC1G_00040T0 NODE_4204_length_20667_cov_33.873905_4 3e-46

How can I prevent my string from becoming a numeric value?
