Hi Ged,
Cinly has good comments, to which I'll try to add.
The restrictions in NIfTI are:
- Each dimension size must be less than 2^15, since dim[]
is an array of shorts. That is a permanent limitation.
- Since nvox is of type size_t, a 32-bit machine is limited
to a 4 GB dataset. However, that isn't really important,
since a file is limited to 2 GB (on a 32-bit machine).
- On a 64-bit machine, each volume (and therefore each dataset)
is only limited by your RAM (though dim[] is still short).
Note that reading and writing datasets via the nifti_brick_list
structure allows handling data as an array of volumes, rather
than one contiguous block of data.
- rick
