Hi guys, Trying to run an ICA on my data I get ??? Error using ==> eval Undefined function or variable 'unknown'. Error in ==> scalingfactor at 165 eval(sprintf('newunit = %s;', new)); Error in ==> scalingfactor at 87 factor = cellfun(@scalingfactor, old, new); Error in ==> ft_apply_montage at 266 scale = scalingfactor(input.chanunit, montage.chanunitorg); Error in ==> ft_componentanalysis at 747 comp.(sensfield) = ft_apply_montage(data.(sensfield), montage, 'balancename', 'comp', 'keepunused', 'yes'); input arguments were: cfg=[]; cfg.method='fastica'; cfg.numcomponent=3; %just for testing comp=ft_componentanalysis(cfg,data_all); data_all structure has the following fields: data_all = label: {274x1 cell} trial: {1x341 cell} time: {1x341 cell} sampleinfo: [341x2 double] grad: [1x1 struct] cfg: [1x1 struct] trialinfo: [341x1 double] Looks like some field is being assigned as 'unknown' (because some subfunction cannot categorise it) and then this string is being evaluated later on leading to an error. The data is regular MEG data from the CTF at the donders.

see bug 2570, I guess Robert made a fix without checking. I'll fix, wait a sec ;)

svn ci scalingfactor.m -m "bugfix #2571 - eval statements fixed" Sending scalingfactor.m Transmitting file data . Committed revision 9494. changed to 'new' (in the following line 'old')

(In reply to Jörn M. Horschig from comment #1) indeed my bad, thanks for the quick fix.
