[Pytables-users] problem to store a multidimensionnal dataset in a table

[<phi...@ho...>]

Hi list,

I want to thank you a lot because i made real progress to achieve my aim 
and it's due to the pytables capabilities and the developper's community.

I got a problem to organise my data in the hdf5 file.

The problem is the data are linked together.

For exemple, i have a pressure depending from the time and space 
coordinates.

I can easily store time in an hdf5 array.
What about space coordinates? Is it better to store it in a table with 
each column corresponding to a dimension (x,y,z) ot to have independant 
array (one for x values, one for y values, and one for z values)?

Furthermore, here is the complex aspect:
pressure is depending on 4 dimensions (time, x, y, z).
I want to store it in a table but i really don't know how because:
It is the combination of a a value for time a value for x a value for y 
and a value for z that gives me a pressure value.

If i have 4 values for time, 4 values for x, 4 values for y for values 
for z, it makes me 1 024 values to store with hierarchy dependancies.

Has someone an idea about this problem or perhaps a solution?
