I have some source data in this format (from 'dics') source = dim: [15 18 15] freq: 39.9818264425261 time: 0.199999999999991 cumtapcnt: [515x1 double] pos: [4050x3 double] inside: [1x2015 double] outside: [1x2035 double] method: 'average' avg: [1x1 struct] cfg: [1x1 struct] If you run ft_checkdata(source, 'datatype', 'source') (which is run in 'ft_sourcegrandaverage' line 86). then it crashes at line 583. Error using reshape To RESHAPE the number of elements must not change. It's because it's trying to reshape the source.pos field. I did not notice the error before because, since yesterday (r5480), parameterselection can handle higher-dimensional data I suggest to add the field 'pos' to the 'exclude' fields (line 560 of ft_checkdata) exclude = {'cfg' 'fwhm' 'leadfield' 'q' 'rough'}; Let me know what you think about it. Thanks!

Hi Giovanni, Sorry, my fault. Indeed probably introduced by yesterday's change. I think that adding 'pos' to the exclude is a good idea. Could you take care of that? Thanks, JM

(In reply to comment #1) Ok, I'll do it. Just wanted to be sure that "exclude" is the best solution
