Fieldtrip interpolate bad channels

Hi all!

I'm trying to interpolate certain bad channels in my EEG data with Fieldtrip toolbox, but the code I'm using is not working. Can you find anything wrong in my steps?

First I use this code to define neighboring electrodes (which seemed sucessful):

cfg = [];

cfg.channel = {'Oz'};

cfg.method = 'template';

cfg.template = 'biosemi64_neighb.mat';

neighbours = ft_prepare_neighbours(cfg);

Then I used the following code to interpolate bad channels:

cfg = [];

cfg.missingchannel = {'Oz'} % I've tried this or using: data.label ('OZ');

cfg.method = 'weighted';

cfg.neighbours = neighbours;

data_fixed = ft_channelrepair(cfg, data);

It shows error:

What should I change?

@doc:fieldtrip finds nothing in the Mathworks doc files; you'll have to at least identify what the Fieldtrip toolbox is/where it comes from. Support from that source is probably the better shot; it doesn't appear to be a Mathworks product.
