In OpenDX, it's called a 'productarray'. You can read about it in the Users Guide, Appendix B-2, Native File Format. I doubt you can import using 'general' format, but native format gives you much more power, including this feature, so is worth learning anyway (and not difficult).

I'm trying to import charge some charge density data into DX, but can't seem to find a solution for non orthogonal systems...
That is:
I have three cell vectors a,b,c, where \alpha, \beta and \gamma are \ne to 90 degrees. I then have values of charge density at
(0,0,0)
(0,0,1)
...
(n_a,n_b,n_c)
, where the first indice is the number of a-vector translations, the second the number of b-vector translations and so on.
Does anyone know of a way to import this, or if dx supports this?
Can I submit it in a scattered format?
