Possible duplicate of slice information in IntracellularElectrode and NWBFile

[lvsltz]

The docs of these two Datasets read, respectively,

Information about slice used for recording.

and

Description of slices, including information about preparation thickness, orientation, temperature, and bath solution.

They seem to refer to the brain tissue prepared on a slide. Since NWBFile.slices can be used for any type of physiology, perhaps the IntracellularElectrode.slice should be removed. If not, what is its role ?

[t-b]

NwbFile is the global info and IntracellularElectrode is the per electrode info.

This is clear; I just don't see what kind of information has to go in the NWBFile and not in IntracellularElectrode, or vice versa. Both of these fields are free text so basically anything fits.

Or the presence of a slice in both locations implies that the relation slice-electrode is one-to-one, instead of one-to-many ?
