Dear fieldtrip-developers, I have been silent for a while, I hope that counts for something :) Anyway, with the most recent version ft_volumerealign doesn't work for us anymore (thanks to Carol Sanchez for finding this). What happens is that when reading an mri (tested different types) which results in something like: mri = anatomy: [256x256x256 double] dim: [256 256 256] transform: [4x4 double] unit: 'mm' cfg: [1x1 struct] (here resliced with ft_volumereslice, but that doesn't matter for the error) cfg=[]; cfg.method = 'interactive'; cfg.coordsys = 'neuromag'; mri_aligned = ft_volumerealign(cfg,mri); crashes with the error: Reference to non-existent field 'scalp'. Error in ft_volumerealign>cb_redraw_surface (line 927) ft_plot_mesh(opt.scalp, 'edgecolor', 'none', 'facecolor', 'skin') Error in ft_volumerealign (line 417) cb_redraw_surface(h); the problem is, as indicated, in the redraw_surface part wait, I just figured it out: the problem is, that in line 417 it shouldn't be cb_redraw_surface but cb_redraw cause obviously i want to align a non-segmented mri to fiducials or whatever. then it works. cheers p

This is related to a recent addition allowing for clicking on surface plots for marking fiducials (r9928, see bug2707). The problem being that both in case cfg.viewmode = ortho & surface, cb_redraw_surface(h); is called, which in turn calls plot_mesh with opt.scalp as input. The latter only being available if there is surface data. As Philipp indeed suggested, it seems that the line should have been cb_redraw in case of ortho viewmode. I'll make the change.
