Matlab h5read get errors
显示 更早的评论
Hi,
When I use
h5read('wo.h5',,'/g4/lat'),
got some errors as below: Error using h5readc The HDF5 library encountered an error and produced the following stack trace information:
H5G_traverse_real component not found
H5G_traverse internal path traversal failed
H5G_loc_find can't find object
H5Dopen2 not found
Error in h5read (line 58) [data,var_class] = h5readc(Filename,Dataset,start,count,stride)
I am using Matlab 2013b, Does it matter with this? Thanks for help.

- There is a typo, two commas where there should be one.
- The reason to the error is most likely that '/g4/lat' doesn't exist in your file. A typo?
I have found the program HDF5View very useful when working with HDF5-files. See HDF5 Tutorial: Learning HDF5 with HDFView
Agree, the error messages could have been more user friendly.
A little test with R2013a. The dataset, '/g4/lat', does not exist in 'myh5file.h5'. I get the same error message as you did.
>> h5read('myh5file.h5',,'/g4/lat')
h5read('myh5file.h5',,'/g4/lat')

Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.
>> h5read('myh5file.h5','/g4/lat')

Hi,If the dataset, '/g4/lat', does not exist in 'myh5file.h5'.So how should I read an entire data set of this file?

Repaced the exception as given in the @jason answer. https://in.mathworks.com/matlabcentral/answers/44650-determine-if-variable-name-exists-in-netcdf-file
if parameter does not exist then give nan values wherever exception match.
