Hi. I successfully performed AEC connectivity analysis on source-based HD-EEGs, getting similar mean connectivity values to other literature. However when I try to perform wPLI connectivity analysis on the same HD-EEGs (but focusing on a selection of scouts relevant to the DMN rather than all 68 dessikan-killarney nodes) I keep getting values of all 1 or NaN, rather than a range between 0 and 1 as expected. I'm not sure if there's something else I need to do prior to the connectivity step to process the data differently, as I assume these values aren't a true representation of the wPLI. Any advice would be very helpful, thanks.
@uqlhaine, please provide more details on the parameters that are being used in the wPLI computation.
