Dear SPM developers,
I am a user of SPM12 source analysis and I am currently working on a
project which aims to project long-term EEG recordings of sleep or motor
data into the source space. We are mainly interested in the projection
of the whole recording into the source space for further connectivity
analyses. Now since MATLAB cannot exceed a certain data length, how
should we invert the data? Should we invert the single conditions after
averaging or should we just invert the data epoch by epoch? What would
be a wise EEG segmentation approach? Would it be justifiable to use a
different inverse operator for every epoch/condition and then process
the whole source-space data set as if it were inverted in a single step?
Best regards and many thanks in advance,
Laith Hamid
