we are using fieldtrip20161014 in the Marseille workshop. It seems as if the computations go through correctly, but for some reason the intermediately reshaped data (linear representation of all vox-by-vox crsspctrm) is not converted back.

I am continuing the discussion in this bug, some stuff has been posted erroneously in bug 3211. I can confirm the issue, and it seems to occur in the situation where there are fewer dipole locations than observations, causing the function to end up in a different corner of the code, somehow preventing correct dimensionality handling.

Created attachment 818 source positions and dim

ok , I've uploaded the file with positions and dimension. Sorry for posting in elsewhere :)

No worries. I fixed the issue with a pull request on github. The version on should work fine now. Could you confirm? If so, please close the bug
