usage: h5diff [OPTIONS] file1 file2 [obj1[obj2]]
|
|
file1 File name of the first HDF5 file
|
|
file2 File name of the second HDF5 file
|
|
[obj1] Name of an HDF5 object, in absolute path
|
|
[obj2] Name of an HDF5 object, in absolute path
|
|
OPTIONS
|
|
-h, --help Print a usage message and exit
|
|
-V, --version Print version number and exit
|
|
-r, --report Report mode. Print differences
|
|
-v, --verbose Verbose mode. Print differences, list of objects
|
|
-q, --quiet Quiet mode. Do not do output
|
|
-c, --compare List objects that are not comparable
|
|
-N, --nan Avoid NaNs detection
|
|
-n C, --count=C Print differences up to C number
|
|
-d D, --delta=D Print difference when greater than limit D
|
|
-p R, --relative=R Print difference when greater than relative limit R
|
|
|
|
C - is a positive integer
|
|
D - is a positive number. Compare criteria is |a - b| > D
|
|
R - is a positive number. Compare criteria is |(b-a)/a| > R
|
|
|
|
Modes of output:
|
|
|
|
Default mode: print the number of differences found and where they occured
|
|
-r Report mode: print the above plus the differences
|
|
-v Verbose mode: print the above plus a list of objects and warnings
|
|
-q Quiet mode: do not print output
|
|
|
|
Compare criteria
|
|
|
|
If no objects [obj1[obj2]] are specified, h5diff only compares objects
|
|
with the same absolute path in both files
|
|
|
|
The compare criteria is:
|
|
1) datasets: numerical array differences 2) groups: name string difference
|
|
3) datatypes: the return value of H5Tequal 4) links: name string difference
|
|
of the linked value
|
|
|
|
Return exit code:
|
|
|
|
1 if differences found, 0 if no differences, 2 if error
|
|
|
|
Examples of use:
|
|
|
|
1) h5diff file1 file2 /g1/dset1 /g1/dset2
|
|
|
|
Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
|
|
|
|
2) h5diff file1 file2 /g1/dset1
|
|
|
|
Compares object '/g1/dset1' in both files
|
|
|
|
3) h5diff file1 file2
|
|
|
|
Compares all objects in both files
|
|
|
|
Note) file1 and file2 can be the same file. Use
|
|
|
|
h5diff file1 file1 /g1/dset1 /g1/dset2
|
|
|
|
to compare '/g1/dset1' and '/g1/dset2' in the same file
