Hi

Make sure to install the NWB Matlab toolset beforehand: https://github.com/NeurodataWithoutBorders/matnwb

Follow this tutorial to work with the nwb format: https://cellexplorer.org/tutorials/nwb-tutorial/

Let me know if this fixes your issue.

thank you, I've added the toolset.
I intend to save a batch cell_metrics, and it now sends this error, that makes sense, the batch cell_metrics.general doesn't have the "basepath" field but basepaths...

cell_metrics.general.basename
ans =
'batch of sessions'

nwb_file = [cell_metrics.general.basename, '.cellmetrics.cellinfo.nwb'];
nwb = saveCellMetrics2nwb(cell_metrics, nwb_file);
Unrecognized field name "basepath".

Error in saveCellMetrics2nwb (line 22)
'session_description', cell_metrics.general.basepath, ...

should I save the cell_metrics for each session to nwb, one at a time?

Hi. Sorry for not getting back to you sooner, but unfortunately, I can't troubleshoot from these copied lines. Could you share your dataset with me?

In general, I recommend saving the sessions individually, but saving a batch of sessions together is possible.

Hi Peter,

No worries! I've sent you an email with my dataset. I'll try saving my sessions individually in the meantime.

Thanks!
