[NBThelp] problems about DFA calculation

[姜时泽 <jia...@gm...>]

Dear NBT experts,
I am starting to analyze some EEG data with NBT toolbox following tutorials
on the web.
Below is the input for calculating DFA an it always come with an error when
I perform nbt_doDFA. The error message is attached in the end. Can you help
me to figure out what was wrong with this? Many thanks.


[Signal,SignalInfo,SignalPath] = nbt_EEGlab2NBTsignal(EEG,0);
[AmplitudeEnvelope, AmplitudeEnvelopeInfo] =
nbt_GetAmplitudeEnvelope(Signaldata, SignalInfo, 1, 40, 2/1);
[DFAobject, DFA_exp] = nbt_doDFA(AmplitudeEnvelope, AmplitudeEnvelopeInfo,
[4 30], [0.5 300], 0.5, 0, 60, []);


below is the matlab error
