[FieldTrip] ft_componentbrowser problem

[Kanal Eliezer]

Never mind, the problem was my specifying the 'comp' item as a string (with single quotes'1:10') instead of a vector. Thanks for your help -

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?
