Ho do you index in to an hdf 5 variable

I'm trying to open an image matrix stored in hdf5 format (a new format to me). Matrix is 500*500, but represents a time series, where each time step is a seperate image (see below).

h5disp('C:\timeseriestest\data1\') Dataset 'TSim1' Size: 1500x500x500 MaxSize: 1500x500x500 Datatype: H5T_STD_U16LE (uint16) ChunkSize: 1x500x500 ....

Not enough memory to open all bands as a single image (i.e. dat = h5read('C:\timeseriestest\data1\', '/TSim1');). If this were possible I could just index into the matlab array.

Is there a simple way to index in, and pull one band at a time for analysis equivalent to:

for i = 1:1500, dat = mydata(:,:,i) .... etc ?

Thanks
