Re: 'grouping' substrings?

I'd make use of Perl's @- and @+ arrays produces by regexes:

my $seq = "...";
my @groups;
push @groups, [$-[0], $+[0]] while $seq =~ /M+/g;
print "$_->[0] to $_->[1]\n" for @groups;

This gives me different values than you've shown, but I believe it's correct.

Yes, don't mind what I wrote, it was just an example... will try your code ASAP. Will also check index function.. thanx to both of you!	[reply]

Sorry to bother you again, but it doesn't seem to work. For example, the first group gives 5-16, while it should be 5-15, the second 32-45, while it should be 32-44 from what I can calculate... Are my maths poor??? Also, I can't understand what [$-[0], $+[0]] mean... Any tips ? Sorry, I'm just beggining Perl...	[reply]

I hope this isn't too obvious, but how about subtracting one from `$+[0]`? Updated per ikegami's reply - duh! I have a bad track record lately...	[reply] [d/l]

`[ ... ]` means "Construct an array with '...' as content, and return a reference to it." This is documented in perlref. `$-[0]` and `$+[0]` are elements of the special arrays `@-` and `@+`. Refer to perlvar for more information.	[reply] [d/l] [select]
