So, remove the N's at the beginning and at the end, and use your old algorithm:

$sequence =~ s/^N+|N+$//g;

This is the one issue in this thread: the OP has not specified if he wants to keep leading and trailing Ns or whether he wants to have them removed. Some answers assume the former, others the latter....	[reply]
