bug using planarcombine and with planar 4d/bti data

[jan-mathijs schoffelen]

Dear Mark,

Thanks for the suggestion. I was wondering whether you are using an up-
to-date version of fieldtrip, because I looked up the log of senstype
and as far as I can see this issue has been resolved a while ago. I
must confess that I have not recently encountered your reported issue
on my own bti-data.

Best
