QSAR problems

Dear all

I have generated a QSAR model with GFA and PLS on a training set of compounds, now I would like to use these 2 models to predict the activity values (IC50) for a another set of compounds, but I am not sure how to do it

I tried with Calculate Molecular Properties, and I choose the GFA / PLS model, but I got only the statistics on this new set of compounds (Mean, STDev,N, Min, Max), not the IC50

Any help will be really appreciated,

Thank you very much in advance
