report from Marseille workshop: in a standard approach, one of the participants ran into the thing that has been mentioned in the title. At first sight, all seems to have been executed OK, so it's not clear to me what is happening. - try and quickly replicate this - if the problem is indeed persistent: fix it we are using fieldtrip20161014

my first attempt at reproduction of this bug failed surprisingly. I did it on my Mac (OS el capitan), matlab 2015b + latest version of fieldtrip, interpolating a randn(npos,1) 'avg.pow' field of the standard sourcemodel 10 mm onto the single_subj_T1.nii No reshaping problems etc.

Created attachment 817 source and source_conn

Reminder: The problem arose when only few positions were selected to compute source activity. To compute source connectivity cfg.method = 'coh' and cfg.complex = 'absimg'. The coherence spectrum is not well-reshaped and the positions are duplicated. I have uploaded the 'source' and 'source_conn' structure

(In reply to Hesham from comment #3) Ah, I see. Then it probably translates to the fact that if the pos-list is not reshapable into a 3D, this strange behavior happens. Can you upload the original (full) pos-list, and the dim-vector (i.e. number of x/y/z voxels)?

Oh, and actually you uploaded the stuff in the wrong bug :o), should have been 3212

It has not been possible to reproduce this. Since I did not receive feedback when asked, there's no use to keep this open.
