Dear fieldtrippers,
While performing statitstical analysis on time-frequency EEG data, I get the following error:
??? Undefined function or variable "sens".
Error in ==> neighbourselection at 106
if ~isstruct(sens)
Error in ==> statistics_wrapper at 226
    cfg.neighbours = neighbourselection(cfg,varargin{1});
Error in ==> freqstatistics at 132
[stat] = statistics_wrapper(cfg, varargin{:});
Error in ==> fieldtripstatanalyse at 70
[stat] = freqstatistics(cfg, stimulusFFT, baselineFFT);
The neighbourselection function tells:

if ~isstruct(sens)

error('Did not find gradiometer or electrode information.');


which gets its data by:

% Revision 1.6 2006/07/12 14:14:59 roboos

% get sens from data.grad/elec


I get this error on several matlab and fieldtrip versions. Any suggestions how to solve this?
