TopoplotTFR

[Vladimir Litvak]

I looked at the code and the problem is in line 264 of topoplotER where you
assume that the yparam is always the second dimension in the data and the
xparam is always the third. When this assumption is false, the code fails.



Best,



Vladimir

Oops. I'm sorry, I misread your mail; I thought you were talking about
multiplotTFR.

Forget what I said before. To my knowledge, a subplotted topoplotTFR only
works in the time dimension, but I'm not sure. Did you check the code?

So if it is true, that it only works in the time dimension, there are two
ways of doing what you want:



Repeatedly call topoplotTFR for different frequencies,

or adjust the function such that it also works the other way.



Maybe you could look into if and why the assignment of the yparam and xparam
should always be 'time', and 'freq' respectively. I guess the original
reason stems from the fact that we are used to depict TFRs like that.



Yours,



Jan-Mathijs

Dear all,



I'm trying to use topoplotTFR for multichannel data that has both time and
frequency dimension. When I configure:



cfg.xparam='time';

cfg.yparam='freq';

cfg.xlim=[-2:0.1:0];

cfg.ylim=[8 12];



I get multiple plots corresponding to different time windows. However when I
try:



cfg.xparam='freq';

cfg.yparam='time';

cfg.xlim=[0:2:40];

cfg.ylim=[-1 0];



or



cfg.xparam='time';

cfg.yparam='freq';

cfg.xlim=[-1 0];

cfg.ylim=[0:2:40];



it doesn't work. I either get an error or a single plot. How do I get a
series of plots for different frequencies with the same time window?





Thanks,



Vladimir
