Hi,

I'd like to bring up another comment on the proposed snirf format (if not too late...).

In the description of the "ml" structure, there is a note specifying that "source indices generally refer to the optode naming (probe positions)".

What if the optode naming is different from the source/detector indices? It is usually the case with our system.

I guess a potential solution would be to add optional fields to SD? We could then have something like "SrcLabels" and "DetLabels" fields, which could indicate the name/label of the optode to be used.
I think this would avoid a lot of confusion when reviewing the data. As an example, the first optode used could be S4 on the device, not S1.

Thank you,

Mathieu
