I am in the process of converting a csv which has 200 fields into a
hdf5 file. I was wondering would creating a 200 column dataset be a
problem?
I currently have something now and when I try to view the document
using HDFviewer it crashes and created a core dump.
Is there a better way to do this?
TIA
Hello,
There is a limit on the number of fields you can have in a compound datatype. This is due to the 64K limit on object header messages, into which datatypes are encoded. If types of the members are simple enough, you should be OK.
Have you tried h5dump on your file?
HDFView support for compound datatype is limited, but it shoudn't crash. I would suggest to try the latest release v2.5 patch 3 http://www.hdfgroup.org/ftp/HDF5/hdf-java/v25p3 and if it still has a problem, please send us your file (help@hdfgroup.org).
Thank you!
