":": no namespace, default: "hdf5:"
|
|
E.g., to dump a file called `-f', use h5dump -- -f
|
|
|
|
Subsetting is available by using the following options with a dataset
|
|
attribute. Subsetting is done by selecting a hyperslab from the data.
|
|
Thus, the options mirror those for performing a hyperslab selection.
|
|
The START and COUNT parameters are mandatory if you do subsetting.
|
|
The STRIDE and BLOCK parameters are optional and will default to 1 in
|
|
each dimension.
|
|
|
|
-s L, --start=L Offset of start of subsetting selection
|
|
-S L, --stride=L Hyperslab stride
|
|
-c L, --count=L Number of blocks to include in selection
|
|
-k L, --block=L Size of block in hyperslab
|
|
|
|
D - is the file driver to use in opening the file. Acceptable values
|
|
are "sec2", "family", "split", "multi", "direct", and "stream". Without
|
|
the file driver flag, the file will be opened with each driver in
|
|
turn and in the order specified above until one driver succeeds
|
|
in opening the file.
|
|
F - is a filename.
|
|
P - is the full path from the root group to the object.
|
|
N - is an integer greater than 1.
|
|
L - is a list of integers the number of which are equal to the
|
|
number of dimensions in the dataspace being queried
|
|
U - is a URI reference (as defined in [IETF RFC 2396],
|
|
updated by [IETF RFC 2732])
|
|
B - is the form of binary output: MEMORY for a memory type, FILE for the
|
|
file type, LE or BE for pre-existing little or big endian types.
|
|
Must be used with -o (output file) and it is recommended that
|
|
-d (dataset) is used
|
|
Q - is the sort index type. It can be "creation_order" or "name" (default)
|
|
Z - is the sort order type. It can be "descending" or "ascending" (default)
|
|
|
|
Examples:
|
|
|
|
1) Attribute foo of the group /bar_none in file quux.h5
|
|
|
|
h5dump -a /bar_none/foo quux.h5
|
|
|
|
2) Selecting a subset from dataset /foo in file quux.h5
|
|
|
|
h5dump -d /foo -s "0,1" -S "1,1" -c "2,3" -k "2,2" quux.h5
|
|
|
|
3) Saving dataset 'dset' in file quux.h5 to binary file 'out.bin'
|
|
using a little-endian type
|
|
|
|
h5dump -d /dset -b LE -o out.bin quux.h5
