[FieldTrip] ft_componentbrowser problem

[Kanal Eliezer]

Hello Dr Schoffelen -

Thanks for the quick reply. I've been periodically updating from the SVN directory, but it appears my local working directory had become  messed up. The file is now found.

However, it seems to have uncovered another error:

~~~~
>> cfg = struct('comp','1:10','trial','1','layout','neuromag306all.lay','channel','M*');
>> ft_componentbrowser(cfg,components);
reading layout from file neuromag306all.lay
??? Error using ==> rdivide
Matrix dimensions must agree.

Error in ==> ft_componentbrowser>plottopography at 172
    ft_plot_topo(cfg.layout.pos(cfg.chanidx.lay,1), cfg.layout.pos(cfg.chanidx.lay,2), ...

Error in ==> ft_componentbrowser at 116
plottopography([], cfg, comp)
~~~~

Once again, any ideas? Thanks -

Elli

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?
