Re: confused with distances

Probably just an array of arrays for each helix. Make it an AoAoA if you want to have an array of helixes.

my $helix_1 = [[-1.115,   8.537,   7.075],
               [-2.745,   5.280,   7.165],
...

The first atom is $helix_1[0] and the z component (for example) of that would be $helix_1[0][2].

Update: As johnqq notes, I need to make things agree. I'd probably do

my @helix_1 = ([-1.115....

I think you probably need to de-reference `$helix_1` as you have created a ref. to a list, not a list. The first atom should be `$helix_1->[0]` and the z component `$helix_1->[0]->[2]`. There are other notations to do de-referencing but this is the style I find most readable. Cheers, JohnGG	[reply] [d/l] [select]
