Dear Omar,
We responded via e-mail as well.
Defining a test set is in our feature list, however notice that as long as the collection is big enough, the current cross validation process should be fine and provide accurate results.
Would you prefer to download the raw spectrum and use your own analysis tools?
This feature will also be available in the future by upgrading to SCiO’s Researcher kit.
Ayelet,
