Fieldtrip ft_connectivityanalysis
WebFieldTrip is the MATLAB software toolbox for MEG and EEG analysis that is being developed at the Donders Institute for Brain, Cognition and Behaviour in Nijmegen, the Netherlands together with collaborating institutes. The … WebHi dear FieldTrip community, I'm trying to get the coherence spectrum between 2 LFP signals (based on the tutorial: "Analysis of sensor- and source-level connectivity"). This is sleep data, so I have only one long "trial" generated with ft_redefinetrial (). I can run ft_freqanalysis () without problems, but both for 'mtmconvol' and 'mtmfft' the ...

WebWe will use the FieldTrip function ‘ft_connectivityanalysis’ for the actual computation of connectivity. In particular, we will estimate the imaginary part of the coherency (Nolte et al., 2004), by specifying cfg.method = ‘coh’ and cfg.complex = ‘absimag’.
