Problems with loading study (all existing subjects disappear)

1

Dear brainstorm gurus,

We have an existing study protocol with hundreds of subjects analyzed. While loading a new subject's anatomy folder, it froze so we exited the matlab. After re-opening brainstorm, all subjects disappeared from that study protocol, but their actual study study and individual subject's folders still existed in brainstorm_db folder. Perhaps during the frozen and force quit process, something was incorrectly written into the brainstormstudy.mat?

However, each subject's data can be reloaded one by one by creating a new subject and entering their ID, we we still have to reload the data individually after the ID is created. Given there are hundreds of subjects, is there a way find out what was wrong in the top level mat file to avoid manual reloading one by one?

We tried to run db_reload_database('current') and got this error message:

There is a folder that points at a subject "New folder".
If you have a subject-level folder named "New folder" in your database (anat or data folder):

  1. Quit Brainstorm
  2. Delete the subject "New folder"
  3. Delete the file protocol/data/protocol.mat
  4. Restart Brainstorm

Make regular backups of your database, this is only way you are never going to lose any data or time, like any computer work.
