topoplotTFR on planar gradients

[Walther Alexander]

Dear Fieldtrip Users,

I'd like to apply the multiplotTFR function on freqstatistic results.
The MEG raw data were converted to planar gradient scores and passed
freqanalysis. Using fieltrip version 2008-12-08, the error message
'unsupported MEG sensor type' occurres which goes back to
prepare_layout.m, line 880. Apparently, though senstype.m gets me the
right information (ctf275_planar) that should be used to create an
appropriate layout, prepare_layout ignores this and directly heads for
the error message. Planar gradient settings seem to struggle somehow
with grad2lay.m (line 259). If I switch to Fieltrip-20090803, it will
create the plot thats attached. My configuration settings read as follows:

cfg.maskparameter = 'mask';
cfg.zparam = 'stat';
cfg.interactive = 'yes';
cfg.zlim = [-4 4];
figure, multiplotTFR(cfg,data)


Given unconverted raw data, everything works out well. Any advice?

Cheers

Alex
