i have a HDF5 Data with following structure:

>> h5disp('NT_D1_3_120516_00004_data_000001.h5')

HDF5 NT_D1_3_120516_00004_data_000001.h5

Group '/'

Group '/entry'

Attributes:

 'NX_class':  'NXentry'
 Group '/entry/data' 
Attributes:
 'NX_class':  'NXdata'
Dataset 'data' 
Size:  2070x2167x77
 MaxSize:  2070x2167xInf
Datatype:   H5T_STD_U32LE (uint32)
 ChunkSize:  2070x2167x1
 Filters:  unrecognized filter (HDF5 lz4 filter; see http://www.hdfgroup.org/services/contributions.html)
 FillValue:  0
Attributes:
 'image_nr_low':  1
 'image_nr_high':  77

There are 77 images withi 2070x2167points. i can read the data with MatLab:

>> data = h5read('NT_D1_3_120516_00004_data_000001.h5','/entry/data/data')

and get a long list of numbers: see attachment.

now i need 77 images.

How can i get them?

Hi, I am experiencing the same problem (but cannot even get the numbers because of the lack of a HDF5 lz4 filter). Did you manage to figure out a solution?
