[Eeglablist] PAC Tools Error/Question

[Aaron Jones]

Hi Ramon,

Thanks for the response! I wonder if you could clarify the sentence, "At
this point, using PACTools for STUDY requires the previous computation of
time-frequency measures (ERSP) for all the subjects in the STUDY."? I have
precomputed ERSP measures both for channels as well as components (both
from the STUDY GUI) prior to trying to use the toolbox (and receiving the
error). Are there additional measures to compute or steps that I need to
take to avoid the error?

Thanks so much for your help!

Aaron
