Attached is the output from a call to sourceinterp on source analysis
output data. I am trying to use the DICS method, but my output
looks nothing like the tutorial pictures. I am including what I
believe to be the relevant code, and advice on the source of my
mistake(s) would be appreciated:<br><br>
[EEG com] = pop_loadbv('/home/bjr39/FTsource', 'B22001hal.vhdr')<br>
EEG1 = pop_select(EEG)<br>
help eeglab2fieldtrip<br>
data = eeglab2fieldtrip(EEG1, 'preprocessing')<br><br>
<font color="#FF0000">%%%<br>
there is some code which I have not included that string matches my
electrodes and uses coordinate that put the sites in MNI space according
to the coordinates listed

</a>%%%<br><br>
</font>cfg.output = 'powandcsd';<br>
cfg.method = 'mtmfft';<br>
cfg.foilim = [5 100];<br>
cfg.tapsmofrq = 2;<br>
cfg.foilim = [35 45];<br>
freq = freqanalysis(cfg, data)<br><br>
cfg = [];<br>
cfg.method = 'dics';<br>
cfg.frequency = 40;<br>
cfg.hdmfile = '/home/bjr39/FTsource/vol.mat';<br>
cfg.resolution = 2<br>
pack;source = sourceanalysis(cfg, freq)<br><br>
sourcePost = sourcedescriptives([], source)<br><br>
cfg =[];<br>
cfg.downsample = 2;<br>
cfg.funparameter = 'nai';<br>
cfg.colmin = 'auto';<br>
cfg.colmax = 'auto';<br>
sourcePostF = source2full(sourcePost);<br>
sliceinterp(cfg,sourceInterp);<br><br>
<br>
I can share more info if it will help, related to the size of different
data structures, or whatever anyone would need to know. I followed
the guide for head model creation and plotted it at various points (one
plot previously posted to the list). Could a poor head model create
this problem?<br><br>
thanks,<br>
