Dear SPM experts,
I have tried to load our 4D MEG data set, that has 148 MEG sensors and 17
non-MEG signals (=165), into SPM8b. After calling Convert from the GUI, I
get a lengthy message (below) but what is worse, the number of channels read
is wrong - it is 290 instead of the correct number 165. Also fiducials are
not read (however, they are available in the header), and other information
seems to be missing as well. I would be grateful for adjusting the reading
of MEG data for 4D-148 sensors machine, if possible.
Best regards
Andrej Stancak
Here is the message I get by calling Convert in SPM8b:
