Hello,
I am trying to visualize 6D arrays of real numbers.
I am an openDX newbie and even though I did search the lists, faqs
and documentation I could not figure out whether openDX could handle
this kind of data or not. From what I could understand, the General
Array Format does not, apparently, permit to define grids of more
than 4 dimmensions. If it's the case is it a limitation of the GAF
or of openDX ? Should I use another software ?
Thanks for your help !

Assuming you mean there are 6 parameters of interest, there are many
ways to visualize this in DX. No, you cannot visualize greater than
3-space but you can conceptually slice 3D spatial domains from
6-space if you want to think of it that way.
The issue is that DX only supports (in the current implementation) up
to 4D positions of which you can only see 3D at a time in the
graphics renderer. But if instead you imagine the other parameters as
data sampled at 1D, 2D, or 3D positions, you can do other forms of
visualizing (realizing) the data using color, opacity,
rubbersheeting, isosurfaces, etc. etc.
So import either a 3D space with 3 uniquely named data parameters
'dependent' on those positions, or import 6 parameters all
conceptually attached to a 1D line of points. Then within DX using
Mark, Compute, Unmark (see docs and examples) you can make any
combination of the 6 scalars into 1D, 2D, 3D positions with 1- to 6-
vector data or scalar data attached to these positions.
If the data is already columnar, consider directly importing it with
ImportSpreadsheet instead of messing with GAF.
