Missing "link to raw" files

Hello,

I am using brainstorm to analyze EEG data. I set up a workspace and linked all the raw data and did some preprocessing. I then made two copies of the protocol, one to be a backup, and then two to do separate sets of analyses on. I completed one set of analyses on one copy without problem. Now I return to the second copy, as well as the initial backup, and have found that several links to the raw data are missing in both. I have checked the underlying folders within the brainstorm_db folder and the folders for the files in question all look comparable to my eye as the subjects that are correct. As far as I remember, there were no errors when I closed out and the first set of analyses on the copy went off without a hitch.

I have attached a screenshot of my erred brainstorm protocol, as well as the underlying folders of a correct subject and a subject missing the link to raw.
In the attached image, The black box shows a correct subject. The red box shows an incorrect subject that shows the file name to the raw file, but it is empty. The blue box shows subjects that are completely missing the links to the raw files. And I have attached arrows showing the file explorer windows of the data folder for the subject in the black box and the subject in the red box. All of the subjects in the blue box look comparable to both as well. Is there a way I can reconnect the subjects missing the link to raw to the data in their brainstorm_DB folders?

Is there a way I can reconnect the subjects missing the link to raw to the data in their brainstorm_DB folders?

Sometimes I get to see empty "raw" folders (missing the data link and channel file) when the import processed crashes before updating the database. This like that can also be observed when multiple instances of Brainstorm are executed in parallel on the same database (Brainstorm at the moment does not support multiple users or parallel executions).

Right-click on Subject 17 > Reload should work to create the missing files in the Brainstorm database explorer. If it doesn't, then you should have an error message in the Matlab command window. Please copy-paste this error message here.

If it works, right-click on the protocol node (top of the database explorer) > Reload, to reload all the subjects.

Thank you Francois. That has helped.
