[FieldTrip] ft_componentbrowser problem

[jan-mathijs schoffelen]

Hi Elli,

Forget about my previous e-mail. I did not read thoroughly your error  
log. The problem does not happen in ft_componentbrowser, but it occurs  
in ft_plot_topo. This function is in fieldtrip/plotting, and it should  
be able to see the functions in fieldtrip/plotting/private, i.e. it  
should be able to locate the inside_contour.m, provided it can be  
found at this location. Could you check whether your fieldtrip version  
has inside_contour in fieldtrip/plotting/private?
If not, I suggest you download a recent fieldtrip version, and try  
again.

Best wishes,

Jan-Mathijs
