Edit nc files
« on: February 13, 2017, 13:34 »
I have a .nc file with a lot of objects in it. Many of which I do not need anymore. To stop bloating the file size and to keep only relevant gIDs what should be done?

Is there any way to selectively remove/delete certain objects from a .nc file?

No need. I did it . Just read and write the configuration files with the needed gIDs.  ;D It was trivial now that I think of it.  ;) :)

Yes, there is no option to remove an object from an NC file, this function does not exist in the file standard. So your way is the correct and only possibility. In ATK 2017 we are switching to HDF5 storage format, that will offer a lot of improved functionality.

Will ATK 2017 have backward compatability? I mean also read .nc files? Please do keep it.

Always. But only for reading - not writing.
