[FieldTrip] no red color for ft_multiplotTFR

[Herring, J.D. (Jim)]

Dear Mante,

As a further clarification, if not specified in the configuration as mentioned by Joern, FieldTrip uses the default Matlab colormap which indeed is Parula (yellow-greenish) as opposed to Jet from MatLab 2014a onwards.

Best,

Jim

Dear Mante,

most likely you are using a Matlab version >2014a. Mathwork changed the default colormap to Parula instead of Jet, see:
http://blogs.mathworks.com/steve/2014/10/13/a-new-colormap-for-matlab-part-1-introduction/
You can change the colormap by using the 'colormap' command in Matlab, or if I recall correctly, also set cfg.colormap= 'jet' (which is doing the same within the ft_ function)

Best,
Jörn

Dear all,



I'm new to Fieldtrip, so I hope this question isn't too stupid :-D. I could not find anything relevant on the previous threads.



When I use the multiplotTFR function (example code pasted below), the hot color is always yellow and never red, even if I set the zlim to extremely small values).



I am using fieldtrip-20150504. What am I doing wrong? I thought the red-blue hot-cold colors were standard. Any help is really appreciated!



Cheers,

Mante

cfg.ylim = [30 100];

cfg.zlim = [-0.1 0.1];

cfg.interactive = 'yes';

ft_multiplotTFR(cfg, grandavg_hi_131_132);
