Dear Eva,

I think you might be using ft_selectdata wrongly, although I would need to see the cfg's you are using to be sure;

Something like this might work:
cfg = [];
cfg.channel = EEG_chan;
data2 = ft_selectdata(cfg, data);

Cheers,
Stephen

Hi,


Hope you are doing well.


I am trying to select all the data with the label EEG from my channels from my .edf file and filter the other channels out (such as bloodpressure).  I tried to use to edf2fieldtrip function and then only select the channels which were needed.


data                 = edf2fieldtrip('myfile.edf');
EEG_chan       = ft_channelselection({'EEG*'}, data.label);

I only want to use the EEG channels, however if I use ft_selectdata it only works if I use the whole data file and not the EEG_chan file. I think the problem lies in that the EEG channels aren't a 'struct'

-

data             = ft_selectdata(cfg, data); (works)

data2           = ft_selectdata(cfg, EEG_chan; (does not work)

Hope you can help me,

Kind regards,
Eva
