Yes,

I have the dataset sorted by ID currently, however I do have separate
datafiles for each subject so I can do this within each sub-file if
necessary.

I wish to have a value from the epoch before the first zero rating and a
value from the epoch after the last zero rating of a run.

IE
        epoch   rating  Epochs of interest.

Does this help clarify.  I am interested in condition prior to zero rating,
and condition after zero rating (even if it is still a rating of zero)  as
there are two treatment groups we wish to see how each group responds to
rating of zero.  Such as prior to zero are other readings higher and do they
stay higher for one group as opposed to another?
