Hello,If the number of  channels of  your data and layout are not the same, there will be error. The alphabetical case is very important, like sometime your data label may be FCZ while the layout is FCz, you need to check that. Meanwhile, to avoid any error, the best option is to design your own layout base on your data as explained in detail in this tutorial http://fieldtrip.fcdonders.nl/tutorial/layoutGood luck!

Subject: [FieldTrip] topoplot - no match between data and layout

Dear Fieldtripers, 

I am trying to represent my data on a topoplotER.  I have averaged all my data with the label "GAshortwm":

GAshortwm = ft_timelockgrandaverage(cfg, avgs{:}); 

cfg = [];                           
cfg.xlim = [-2 1];                
cfg.zlim = [-10 10];                
cfg.layout = 
ft_topoplotER(cfg,GAshortwm); colorbar;

However, I have a recurrent mistake which is  only present with this type of plot, not with other plots like single plot:

Error using topoplot_common (line 561)
labels in data and labels in layout do not match

Error in ft_topoplotER (line 169)
cfg = topoplot_common(cfg, varargin{:});

I'm sure of the layout I'm using (biosemi 64), and I already checked that this layout is detected within my script. Consequently, I don't understand why there is no match between my data and the layout. I though it was because name of the labels are from
 1 to 66 in data files, but it's probably not the reason because it works very well with single plot.

Does anyone have an idea?

Thank you!
