I'm averaging a noisy dataset. Regular averaging works fine, but when I choose 'robust averaging' the following error appears when I try to display the robust averaged dataset.
SPM8: spm_eeg_average (v3497) 12:40:42 - 28/03/2011
Robust averaging finished after 14 iterations.
macefdspm8_P06LB_p01.mat: Number of replications per contrast:
average 1251: 30 trials, average 1751: 90 trials, average 251: 30 trials, average 751: 91 trials, average 1250: 30 trials, average 250: 30 trials, average 1750: 89 trials, average 750: 90 trials, average 125: 60 trials, average 175: 179 trials, average 25: 60 trials, average 75: 181 trials.
Robust averaging might have introduced high frequencies in the data. It is advised to re-apply low-pass filter

Help would be appreciated.
I also noticed that spm_eeg_sort_conditions only works on the merged dataset prior to averaging (when this sorted file is averaged it produces the correct condition order) but doesn't appear to change the order of conditions when used on the averaged dataset. Is this intended?
