I have a query regarding the sliceinterp function. I am trying to plot the
sources of beta power changes. The source activities are the result of a
comparison of left and right hand movement conditions, hence they have a
mirror reversed distribution and amplitude, ranging from say -15 in one
hemisphere to +15 in the opposite hemisphere.
In order to clip the displayed source activities to say [-10 -15] in one
hemisphere and [10 15] in the other (and create opacity maps) I thought I
could use cfg.clipsym = `yes´ (and cfg.maskclipsym).
cfg = ;
cfg.funparameter = 'pow';
cfg.colmin = 5;
cfg.colmax = 15;
cfg.clipsym = 'yes';
However, this doesn´t seem to work since the clipping is performed on only
one end of the scale, eliminating the mirror reversed source at the other
Am I wrong in assuming cfg.clipsym would work here or am I using it in the
(What I´m trying to do is exactly the same as realized in Figure 3 of
Medendorp et al. CerCor 2007).
The aim of this list is to facilitate the discussion between users of the FieldTrip toolbox, to share experiences and to discuss new ideas for MEG and EEG analysis. See also http://listserv.surfnet.nl/archives/fieldtrip.html and http://www.ru.nl/fcdonders/fieldtrip.
