[Eeglablist] Hi, list: help with muscular artifacts

[Srinivas Kota]

I received the following errors when I used clean_rawdata, clean_artifacts.
My data is array is bandpass filtered  with no DC component.

EEG = clean_rawdata(data, 5, [0.25 0.75], 0.45, 5, 0.25);

my data is a 257 by 77624 array. I received this warning













* Attempt to reference field of non-structure array. Error in
clean_flatlines (line 46) removed_channels = false(1,signal.nbchan); Error
in clean_artifacts (line 177)     EEG = clean_flatlines(EEG,flatline_crit);
end Error in clean_rawdata (line 76) cleanEEG = clean_artifacts(EEG,
'FlatlineCriterion', arg_flatline,... Error in check_cleanrawdata (line 14)
EEG = clean_rawdata(data(1:256,:), 5, [0.25 0.75], 0.45, 5, 0.25*

I also tried this
EEG1 = clean_artifacts(data)







*Attempt to reference field of non-structure array. Error in
clean_flatlines (line 46) removed_channels = false(1,signal.nbchan); Error
in clean_artifacts (line 177)     EEG = clean_flatlines(EEG,flatline_crit);
end*




Best,
Srini
