[Eeglablist] Fieldtrip cluster / montecarlo statistics fail for multi-channel ERSP

Hi all!

The title mostly says it all - I am attempting to run fieldtrip cluster /
monte carlo statistics on an eeglab study across all electrodes. This works
fine for ERP, but for ERSP gives the error "the field cfg.neighbours is
required."

This is mentioned in a Bugzilla report (https://sccn.ucsd.edu/
bugzilla/show_bug.cgi?id=1942). The report is marked RESOLVED but the issue
is resolved only for single channel ERSP/ITC; full scalp (multichannel)
cluster correction for time-frequency data still fails.

This is essentially a double post with an unresolved question on the
fieldtrip forum from last October (https://mailman.science.ru.
nl/pipermail/fieldtrip/2017-October/011863.html). The only response
suggested posting to the EEGLAB list.

Any suggestions?

Thanks,
