Your report is not a bug. Gradiometer info is missing from the data. Probably got lost along the way when combining planar gradients. Please contact first line of defence (=group members from neural oscillations group) for a fix. There should be knowledge to deal with this problem (Barbara or Stephen would be good candidates). The problem of neighbourselection has been brought up in your group, according to my information. Refer to that discussion please. I assigned this 'bug' to Saskia to ensure that it will be followed up and documented on the fieldtrip wiki.
