Thanks so much for your reply.
I am just wondering how can I just take away the two consecutive reversed brackets -- ][. Like this: 
my $str = "TGC[CCC]CC[TTT]";

# Into 

my $rep  = "TG[CCCCCTTT]";

Still my regex below doesn't do it right, it also removes two Cs in between: 
$str =~ s/\]([ATCG]+)\[//;

Edward

    That's because your substitution matches the ]...[ part and replaces it with nothing! You'll have to replace it with $1, which in your regex, contains the letters in between the closing and opening brackets. s/\]([ACTG]+)\[/$1/
