in reply to string match using with an N in any position

Just one more, not necessarily better or quicker than the other solutions

if($value =~ m/^(NCGAT|GNGAT|GCNAT|GCGNT|GCGAN|NACGT|CNCGT|CANGT|CACNT|CACGTN).*?$/){do something...}

1. Each of the query strings should be matched only in the beginning of the string 2. The query strings can have an N (and ONLY ONE?) at any position which means for each query string eg. GCGAT we can have NCGAT,GNGAT,GCNAT,GCGNT,GCGAN.

    Why the ".*?$"?

      Just a matter of personal preferences. It will helps me to remember what I was doing in future reviews, but you can avoid it if you want (and gain a little speed).
