Live Z-Scores - how to review?

To review z-score progress, there are a variety of methods.

One of the best is to use the z-score display in BReview.

See for example:

www.brainm.com/software/zprogress.jpg

This is a one-session change.  We are seeing things like this to show
the within-session change very helpful.  You can also flip from session
to session quickly using the "Select" control, and see the changes
as you go from one to the other, in the spread of the z-scores.

You can then use the Z-Score select panel, and select all z-scores
say "greater than 2", and they will be highlighted.  You can count them.
You can then make a summary of how many z scores are outside
various targets.  for example, see:

www.brainm.com/software/zscoreselect.jpg

and

There are other ways to get at the z score
data for now, but these are among the most direct.

Is there way to access the raw data through excel with only z-score information such as the averages for each minute and over the session? Looking for the best measure for pre and post performance to use for SPSS for data analysis such as with ANOVA. Please advise.

Thank you, MJL

We don't have Excel file export of the z-scores, but if you look in the summary file (.bsm suffix) and look, you will see the Z score information in a special field with labels on the values. You can cut and paste these values into excel.
