working with Alex Backus on a tighter integration with source level data obtained with 'pcc' as method. -inventorise whether it works: *which methods? *why doesn't it work for some methods? *fix it.

bash-3.2$ svn commit -m "enhancement - built in support for powcorr_ortho for source level data" ft_connectivityanalysis.m connectivity/ft_connectivity_powcorr_ortho.m test/test_bug2004.m Sending connectivity/ft_connectivity_powcorr_ortho.m Sending ft_connectivityanalysis.m Sending test/test_bug2004.m Transmitting file data ... Committed revision 7536. @Stan: I changed the behavior of ft_connectivity_powcorr_ortho, so that the two correlation coefficients (orthogonalising w.r.t. one or the other) are averaged. Perhaps we may discuss the necessity for this to begin with.

At the moment the test script seems to run through just fine. it checks for coh powcorr amplcorr and powcorr_ortho. Closing for now.

With the new source representation the test function fails in univariate2bivariate, where the 'pow' does not exist (and should probably be computed from the mom :-) ).

test_bug2004 runs through fine it seems. Closing for now.
