Hello everyone,

I've been looking for a solution to my problem on the forum but I'm stuck. If anyone has an idea on how to fix this: I'm unable to reload my protocol... Thanks in advance for any help!

The error :

nrecognized field name "BrainStormSubject".

Hi @Flo7,

It seems there is something wrong with the structure of your Protocol dir, from either a Matlab crash or a manual manipulation of the files.

Now it’s something that has to be fixed manually.
Before you try to fix anything, make a complete backup of all your database if it is not already done. A manipulation error could lead to massive loss of data.

The structure you should have for the protocol is described here:

In your case, it seems there is a file brainstormstudy.mat at the level Protocol_X/data
Is that what you see on your files?

Dear Raymondo,

Thank you for your response and for your help. I found a 'brainstudy.mat' file for every subject, which contains the following data

This could be helpful? Thank again

The content you posted corresponds to a file with name brainstormsubject.mat and not the file brainstudy.mat. Can you confirm this?
