it seems that single trial noise covariances are supported -> with rawtrial. As such this does not really make sense.

I suggest to change ft_sourceanalysis such that it works the same way for the pcc/dics/lcmv and for the mne. This entails the support for keeping filters in mne, and allowing for cfg.singletrial to be activated for mne. In this context, pre-computed filters (based on the average noise covariance) need to be in the input. This entails also support for using precomputed filters in mne

Sorry, where I said cfg.singletrial in the previous post, I intended to say 'rawtrial'

implemented with revision 5066. The logic for mne is now the same as with the beamformers: first compute the spatial filters using the average, and then reconstruct the single trials using the pre-computed filters in cfg.grid.filter = source.avg.filter, and cfg.rawtrial = 'yes';
