In Re: Getting (famous) error during running perl script, BillKSmith suggests blank lines in your input file -- and there's a decent chance that's it.

However, dissecting the line with the issue into digestible form:

if (/>(.*)/)
{
    if (defined $list{$1})
    {
        print $_. "\n" . $hash1{$list{$1}} . "\n"; $x = 1
    }
    else
    {
        $x = 0
    }
}  #e
print $_ . "\n" if $x == 0;  #e

I can't help but wonder: You check to see if $list{$1}is defined, but make no attempt to ascertain if $hash1{$list{$1}}is defined -- but that's what you're using there.

Could it be that you need to change that line to:

    if (defined $hash1{$list{$1}})

If it might help you a bit?
