Need info on warning; "Using virtual epochs to compute inverse"

Hi all,

I am writing to ask further classification about the warning in the as_type function.
In specific, where it says 'Using virtual epochs to compute inverse
Is this warning about using virtual epochs for inverse modelling? Please give further clarification if possible.

Many thanks!

"Warning

Using virtual epochs to compute inverse can yield unexpected results. The virtual channels have ‘_v’ appended at the end of the names to emphasize that the data contained in them are interpolated."
