Dipole fitting method

1

Hi
i have a question form you...
is it possible in Brainstorm to import simulated signals( i mean that the signals those i create myself in my matlab program) instead of real signals for localization process by brainstrom?
for example i caculate three the effects of three active sources on electrodes and then adding noise and interfereing signals to it, then i import it in brainstrom to have localization process with dipole fitting method, is it possible? or we should import juast read EEG signals....
thanks

Hi @haniehsotudeh,

Yes, it is possible! These are two ways you could achieve that:

  1. By generating a matrix file with the simulated signals, adding it to Brainstorm, and review the matrix file raw recordings. See this script:
    brainstorm-scripts/review_simulated_matrix.m at main · rcassani/brainstorm-scripts · GitHub

  2. In a new subject, so right-click then Review raw file, in the field Files of Type select EEG: Matalb matrix (*.mat). Then select a .mat in which you have stored your simulated signals in a matrix, you will need to provide some extra information about the signals:
