(Using version 20131010) cfgst.atlas = 'aal\ROI_MNI_V4.nii'; cfgst.roi = 'Temporal_Mid_L'; cfgst.avgoverroi = 'yes'; cfgst.hemisphere = 'left'; cfgst.inputcoord = 'mni' ; stat = ft_sourcestatistics(cfgst, iRel{:}, iIde{:}); % these are participants' MNEs averaged over a time window, interpolated to the MNI template with .pos and .dim fields copied from the template_grid onto the subjects' source. If cfgst.avgoverroi == 'yes'; error: ??? In an assignment A(:) = B, the number of elements in A and B must be the same. Error in ==> clusterstat at 187 tmp(cfg.inside) = postailobs; Error in ==> ft_statistics_montecarlo at 326 [stat, cfg] = clusterstat(cfg, statrand, statobs,'issource',issource); Error in ==> statistics_wrapper at 298 [stat, cfg] = statmethod(cfg, dat, design, 'issource',issource); Error in ==> ft_sourcestatistics at 107 [stat, cfg] = statistics_wrapper(cfg, varargin{:}); If cfgst.avgoverroi == 'no'; ft outputs only NaNs in stat.posclusters/negclusters. This is regardless of whether cfgst.roi is one label or a cell array. (I can provide example data if necessary, just not attaching now coz I don't have them at home).

Can someone please address this issue? I am having the same error. Thanks, Raghavan

(In reply to Raghavan Gopalakrishnan from comment #1) can you share your data and cfg so that we can reproduce the error? see http://fieldtrip.fcdonders.nl/faq/how_should_i_send_example_data_to_the_developers
