If I have manually localized electrodes, and the number of contact points/channels does not match the number of channels located within the edf file, am I still able to project the edf/eeg info onto those electrodes I have created? I want to see EEG data within the brain without having to process things separately (model the electrodes in Brainstorm but pull EEG data from fieldtrip or EEGLab), and if I could see electrical activity from specific contact points on the electrodes I created that would be amazing.
Yes, it is possible to add locations for EEG (and SEEG) electrodes from an existing channel file. Electrodes must have the same names in the channel file without locations and in the channel file with locations. Then right-click on the channel file (without locations), then Add EEG positions > Import from file and select the channel file (with the locations).
Starting from Brainstorm 06-Aug-2024: if the Channel file is already in the database, there is a simpler way to do so. Right-click on the channel file (without locations), then Add EEG positions > From other studies > STUDY_WITH_CHANNELFILE_WITH_LOCATIONS
@Raymundo.Cassani Thank you so much for this swift reply! However, that only seemed to mess up my data further. Now, because everything seemed off, I deleted all associated files with a particular participant and was just going to start the implantation process over again. However, before even putting in any electrodes or edf data, here is what I saw:
Could this have anything to do with my other ongoing issue of "index exceeds array bounds"?
Also, I was wondering more so if I could project electrical activity onto manually localized electrodes, not upload existing positions. Is this a possibility?
