Phase Amplitude Coupling Paramaters :

  1. Channels to analyze: Select which sets of channels you which to do the PAC analysis on. The channels can be inputted in sequence like this: 1 2 34 5 32. Or you can use the Matlab shorthand to create a vector, for example: 1:129. This is equivalent to listing all the channels from 1 to 129.
  2. Windows length: The windows length is used to calculate the number of segment in the PAC plot. For example, in an EEG with 60seconds of data, if we choose windows length to be equal to 10 we will have 6 segments.
  3. Number of bins: The number of bins is used to sort the amplitude per phase.
  4. LFO bandpass filter: The bandpass filter is used to filter to data to obtain the low frequency component.
  5. HFO bandpass filter: This will filter the data to obtain the high frequency component. This bandpass filter need to be greater than the LFO bandpass filter.
  6. Print check box: By selecting print, when the pipeline will have finished computing the PAC plot will output as a figure to the screen (fig. 15).
  7. Save check box: By selecting save the PAC plot will be saved in the Phase Amplitude Coupling folder under a name that reflect the time at which the analysis was performed. Also, a text file containing the input will be saved using the same name as the figure.
