Dear Brainstorm group,
I did a parallel computation of subjects of the same study on different computers to save time.
Now i want bring them together by zipping the subjects on one computer and import them in the protocol on the other.
When I use the import subject from zip file function i get this error:
but its exactly the same channel file and all the parameters for the anatomy calculation have been like in the new protocol.
Do you have any idea how I can import this files to bring the study together?
My second question: Is there a way to import preprocessed EEG-event series from another protocol with the same channel file?
Thank you!
Best,
Boris
Hi Boris,
Are you using one channel file per subject?
If you are using one channel file only, you should first change the channel file configuration of each subject to “No, use one channel file per folder” or “Yes, use one channel file per subject”.
Then unzip all the subjects .zip files in the same folder, and import the resulting protocol with all the subjects with the menu “File > Load protocol > Load from folder”.
The question of importing pre-processed EEG recordings is more complicated than it sounds. If you have only applied frequency filters, it is fine (just check the quality of the filters with a PSD). If you’ve been applying SSP or ICA projectors, these projectors should be carried to the forward model for the source analysis, and they will not if you just import the recordings.
You can copy-paste the channel file used for one subject to another (or even across protocols) if and ONLY IF there are no SSP/ICA projectors that were used to clean the recordings (http://neuroimage.usc.edu/brainstorm/Tutorials/CreateProtocol#Create_your_first_protocol).
If you copy a file to a folder in a protocol that is already loaded in Brainstorm, right-click on the protocol folder in the database explorer > Reload.
Cheers,
Francois
