Hello trippers, Trying to use this tutorial ( ) with a subject of my own, I got an error. %% housekeeping, add path to fieldtrip addpath('/home/common/matlab/fieldtrip'); ft_defaults %% read in MRI mri=ft_read_mri(fullfile(mridir,mrifile)); %% segment cfg=[]; cfg.output='brain'; segmri=ft_volumesegment(cfg,mri); ft_volumesegment fails Undefined function or variable 'icosahedron42'. Error in ft_plot_axes (line 96) [O.pnt, O.tri] = icosahedron42; Error in ft_determine_coordsys (line 210) ft_plot_axes(data, 'axisscale', axisscale); Error in ft_checkdata (line 547) data = ft_determine_coordsys(data); Error in ft_volumesegment (line 163) mri = ft_checkdata(mri, 'datatype', 'volume', 'feedback', 'yes', 'hasunit', 'yes', 'hascoordsys', 'yes'); Any ideas? Running bleeding-edge fieldtrip on mentat at DCCN.

Probably a typo, should read icosahedron642

I'll look into it

fixed typo in ft_plot_axes as per revision 10931.

(In reply to Jan-Mathijs Schoffelen from comment #3) hmm, there is also a 42 vertex refined version of the icosahedron. It was missing from plotting/private. mac011> svn commit private/ ft_plot_axes.m Sending ft_plot_axes.m Adding private/icosahedron42.m Transmitting file data . Committed revision 10933.
