Re: Why is it matching??

I'm a little confused on what you are doing, but perhaps changing

if ($_ !=~ [$target_name])
[download]

if ($_ !~ /$target_name/) 
or
unless (/$target_name/)
[download]

will fix your problem.

Using unless is the same difference (I tried it just for kicks, and it doesn't help). !~ on the other hand throws my program off completely. The program outputs nothing. Thanks for the input!! Bioinformatics	[reply]

Hmmmmm...maybe you are right. !=~ could be an issue, depending on what has most priority, =~ or !=. If it is the latter, then what the regex effectively says is, if it is not equal to $target_name in reverse...~ by itself (addressing a non-numeric string)returns a string with identical length but with all the bits of the string complemented. I don't know if that effect is changed by the presence of // though... Could I be facing a double negation? If it is the former, then I would assume it would be the rough equivalent of !~.
