I am trying to dump a data set from one of my HDF5 files. Here is the output
from my command line invocation:
503:[mjackson@mine:~]$ h5dump -d /VoxelDataContainer/CELL_DATA/GrainIds -o
/Users/Shared/Data/Ang_Data/Small_IN100_Output/GrainIds.bin
/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 {
}
ATTRIBUTE "NumComponents" {
DATATYPE H5T_STD_I32LE
DATASPACE SIMPLE { ( 1 ) / ( 1 ) }
DATA {
(0): 1
}
}
ATTRIBUTE "ObjectType" {
DATATYPE H5T_STRING {
STRSIZE 19;
STRPAD H5T_STR_NULLTERM;
CSET H5T_CSET_ASCII;
CTYPE H5T_C_S1;
}
DATASPACE SCALAR
DATA {
(0): "DataArray<int32_t>"
}
}
}
}
Looking at the output file "GrainIds.bin" the file size is registered as
26,800,344 bytes which is confusing because if we take the DATASPACE from above
and multiply by 4 (number of bytes in H5T_STD_I32LE) I get 17,778,852 bytes.
This is on hdf5-1.8.10-patch1, compiled on OS X 10.8.2 using the latest XCode
installation from Apple.
Thoughts?
