Unable to remove subject

Discussions
1

HI,

I cannot remove a subject from the anat or functional tree. This happened after I tried to rename a subject and experienced some kind of aborted qlogin session. This left folders with both old and new subject names, some of then with partial contents. I restored the files from a backup and removed the folders associated with the new subject name, but it still shows up. Is there a way to manually edit some file to remove it?

Thanks,
-Jeff

Hi Jeff,

To force the deletion of the subject “SubjectName”, you can do the following:

  • Select your protocol where you have this problem
  • Menu File > Delete protocol > Only detach from database
  • Close Matlab
  • Delete the two folders: protocol_name/anat/SubjectName and protocol_name/data/SubjectName
  • Delete the file: protocol/data/protocol.mat
  • Restart Matlab and Brainstorm
  • Menu File > Load protocol > Load from folder > protocol_name

Cheers,
Francois

I was able to delete it before I got your instructions, but will save for future reference.

Hi again,

I tried your deleteion method and cannot get it to work for the Test subject shown in the screenshot. I am not sure I even created this subject - I think it was created when I made some simulations, which I also cannot delete now. They are gone, but keep showing up ni the list.

Hi Jeff,
Which of the step I was suggesting previously is giving you a hard time?

[QUOTE=Francois;7184]1) Select your protocol where you have this problem
2) Menu File > Delete protocol > Only detach from database
3) Close Matlab
4) Delete the two folders: protocol_name/anat/SubjectName and protocol_name/data/SubjectName
5) Delete the file: protocol/data/protocol.mat
6) Restart Matlab and Brainstorm
7) Menu File > Load protocol > Load from folder > protocol_name[/QUOTE]

Francois,

None of them. I do them all and then load and the subject is still there.

  1. Is this one of the subjects you tried to renamed but you stopped Matlab before it finishes?
    If the structure of the database is correct, the procedure I gave you should work if all the steps are executed in this order. The only references to a subject are the two folders protocol_name/anat and protocol_name/data, and the protocol structure (protocol_name/data/protocol.mat).

  2. What happens exactly when you try to delete the subject from the Brainstorm database explorer?
    Does it disappear from the tree?

  3. Are you using Matlab 2014b pre-release?

  4. At step #5: Is there a file named protocol_name/data/protocol.mat ?

I was successful. I may have messed up step 5 before.
