I used this:
h5dump --dataset=/VoxelDataContainer/CELL_DATA/GrainIds
--output=/Users/Shared/Data/Ang_Data/Small_IN100_Output/GrainIds.bin
--binary=NATIVE
/Users/Shared/Data/Ang_Data/Small_IN100_Output/Small_IN100.dream3d
HDF5 "/Users/Shared/Data/Ang_Data/Small_IN100_Output/Small_IN100.dream3d" {
DATASET "/VoxelDataContainer/CELL_DATA/GrainIds" {
DATATYPE H5T_STD_I32LE
DATASPACE SIMPLE { ( 4444713 ) / ( 4444713 ) }
DATA {
}
}
}
and got what I expected. Not really sure what the difference was except the
--binary=NATIVE argument but I would have thought that was implied with the -o
option?
Sorry for the noise.
