[Eeglablist] PAC Tools Error/Question

[Ramón Martinez]

Dear Aaron,
The error is indicating that PACTools can not recognize if the measure has
been computed. You may want to get the current version of EEGLAB and
re-generate the measures with it. The naming of the measures files changed
a while ago, and while you have a not that old version, you may want to
make sure the files are being generated in a current way. However, I can
not assure you will not find any other issue ahead. The STUDY feature in
PACTools has no been released yet since it is currently under development.
A new release may come by the end of November.
Best,
Ramon
