Thanks for the information.
- I did not check to see that the ncessary pynwb was already installed with pip install allensdk and had installed the latest version. Thanks very much for pointing out this was where this issue was.
In terms of Matlab, I tried loading those extension files but to no avail. It seems like a similar issue to python whereby file conventions have changed since the ecephys nwb files were generated. Perhaps an older version matnwb would also solve this issue, similarly to python.
Thanks for such a quick response, looking forward to using these datasets.
