Hi,
I am trying to use SPM8b, r2448 updates, to work thru the multimodal
faces SPM8b Manual ch. 33 example. I am sort of working back and forth
between instructions in that chapter and in the Source Reconstruction
chapter (15).
I re-did the segmentation of the structural file in the multimodal
tar file, just to be sure it was done in spm8b.
I used the M/EEG Convert button to convert the e_eeg.mat,dat file from
spm5 to spm8 format.
I used the Prepare button to load the sensor locations and fids from
their mat files, in case the convert to spm8 didn't get them.
To enter fids for the structural, I used the Coregister menu item
"type" and typed in the coordinates from the smri_fids.mat file from the
multimodal sMRI directory.
I think I got thru the co-register step OK, and I pressed Save after
that step.
When I press the Forward Model button I get the error below.
What step do I need to do to get the mat info into the dataset ?
Also, the start of section 15.3 in the manual seemed to indicate that
individual head models based on subject's structural were only
supported for MEG. Are individual models also supported for EEG ?
thanks
Kate
