Dear Pytable Experts-
I've created a simple file with one group and three tables. In the
same script, I then load one of the tables. In the next step (later),
I've attempted to create a new table in the same group and the file
refuses to open using either openFile(hf5file,"w") or
openFile(hf5file, "a"). The error message is below.
I am able to open it only to read it. Is there a somewhat obscured
permissioning which needs to be set when the group, etc. are first set
up? I have verified the locations of the pytables file and the input
file for the new table data. Using FC7 as root and the latest
pytables and python versions.
Thank you.
