Hi Jeff,
If you have the newest (2.6 or newer) MNE version installed, you can
specify the --noextra option to remove requirement for the presence of
STI 014. However, all Vectorview data files should have this channel
present. Has the raw data file been preprocessed, e.g., by graph which
may have resulted in this channel being removed?
Best,
Matti
