[FieldTrip] error using ft_channelrepair

[Boomen, C. van den (Carlijn)]

Dear Fieldtrip users,

Currently I'm trying to interpolate EEG data from an EGI system using ft_channelrepair. I run into the same error as is described in this thread: https://mailman.science.ru.nl/pipermail/fieldtrip/2014-March/033537.html but can't seem to find the solution.

The error is the following:
Error using ft_fetch_sens (line 203)
no electrodes, gradiometers or optodes specified.

Error in ft_channelrepair (line 129)
    sens = ft_fetch_sens(cfg, data);

It seems that the ft_prepare_neighbours works well, as the neighbours are described and make sense. The error occurs if I automatically detect the bad channel, if I manually define it, if I use any type of method. For example in the following script where row and column represent a specific channel and trial (which are correctly identified, and the cfg.badchannel shows the actual channel name)


                             cfg = [];

                           cfg.badchannel = datafinal_incl.label(row,1);

                           cfg.trials = column;

                           cfg.method         = 'weighted';

                           cfg.neighbours     = neighbours;

                           data_fixed{1,column} = ft_channelrepair(cfg,datafinal_incl);


Does anyone know what the error and possible solution might be?
Thank you for your help!

Best,
Carlijn
