]]> Comment on PSA: Why using Dataset.value is discouraged in h5py by ac http://alfven.org/wp/2011/11/psa-why-using-dataset-value-is-discouraged-in-h5py/#comment-31 ac Thu, 08 Mar 2012 06:01:37 +0000 http://alfven.org/wp/?p=50#comment-31 Thanks for your inquiry! Yes, you can delete objects in an HDF5 file, using the standard dictionary syntax in python: >>> del myfile['name'] There's no rename method at the moment, at least at the high level interface. You can work around this for the time being by doing: >>> myfile['newname'] = myfile['oldname'] # creates a new hard link >>> del myfile['oldname'] You can also ask questions at the h5py mailing list (h5py at googlegroups), as more people read it.

Here goes; I hope this is simple. I can't find an interface to "rename" nodes in the HDF5 structure or to delete them. PyTables has .renameNode, and HDFView has a "rename" as well as "delete." It is possible yes, to .close() a file, edit with one of the other interfaces, and then open it again with h5py, but this seems like more work than it ought to take. So,... any chance that "rename" or "delete" will be supported sometime soon? (Or, maybe there's someplace I've missed where to get them in existing API?) Thanks for h5py. My application is managing data output from microwave waveforms acquired at 3.6 Gsps on three channels. The simple interface to h5py makes the project look very reasonable.

There's another Python package for reading HDF4 files called PyHDF: http://pysclint.sourceforge.net/pyhdf/ I haven't used it myself but have heard good things about it. Good luck! Hi Curt.

Sounds like it will interface well with CDAT (see above URL). But unfortunately, the files I am dealing with are HDF4, not HDF5. Any advice? Thanks for sharing h5py.
