Undefined function or variable "sens"

[A. Stolk]

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?

 

Regards,

Arjen Stolk
