Hello SPM gurus,
I face a problem when going through the EEG tutorial for spm8b. After
I've converted, montaged, epoched, downsampled, filtered, and remove
artifacts from the data (ie, up through 12.8 in the manual), the data
either does not average correctly or averages right but does not
display correctly.
When I select the afdeM* file after clicking average, I get the
following error messages (though the progress bar goes by quickly, the
gui pops up, and the mafdeM* file is written):
SPM8b: spm_eeg_average (v$Rev: 2715 $) 11:53:15 - 15/03/2009
=======================================================================
Warning: afdeMspm8_example.mat: No trials for trial type 115tandard:

> In spm_eeg_average at 129
mafdeMspm8_example.mat: Number of replications per contrast:
average standard: 0 trials, average rare: 0 trials
And when I try to look at the trials in the gui I get the following errors:
??? Error using ==> axes
Values must be monotonically increasing.
Error in ==> spm_DisplayTimeSeries at 254
ud.v.handles.axes = axes('parent',hp,'position',pos1,...
Error in ==> spm_eeg_review_callbacks>updateDisp at 884
ud = spm_DisplayTimeSeries(D.data.y(:,:,trN(1))',options);

updateDisp(D,1)
??? Error using ==> spm_eeg_review_callbacks('select','switch')
Error using ==> axes
Values must be monotonically increasing.
??? Error while evaluating uicontrol Callback
The gui tells me there are now 2 trials, each of which is a average of 0 events.
I've gone through the tutorial up to this point a few time to make
sure I didn't misread any of the instructions. Any ideas for what's
wrong?
Thanks in advance!
