Ah, I see. I didn't try that at all. >> 2) Shapes and indices are all int, rather than long. This excludes >> really big arrays.

I could theoretically back the data structures with more than > one array, but the maximum index is defined by the int, I think. After a quick look at the Java docs, it seems you are right. This means Java arrays are quite limited in size by today's standards. > >> PS: I am using PersistentMatrix rather successfully in reading data >> from HDF5 files! > > Exciting!

I have been using netCDF a lot in the past, but currently I am switching to HDF5 because it is more flexible and the C library has parallel I/O features. netCDF 4 will be a layer on top of HDF5 as well, so that format seems to have the best future. On the other hand, if you want to deal with existing netCDF files, you have to use the netCDF library. I haven't looked at their Java version yet.
