oh wait, this is confusing, when we discussed this, I thought it was a separate PR. Now it appears that it adds all the other commits from #466 into this resulting in lots of duplicates

[rasbt]

I think the best option is if you could copy your changes, delete this PR, and add a fresh PR in a branch that doesn't have the commits from the EyepadAlign branch #466 (seems like you branched off of the #466 and forgot to change back to master before adding the notebook change)

Yes, this is messed up.

I will close this PR and create a new one.
