Generating a ROC curve for ligand data.

Hi Guys,

I'm having some trouble generating a ROC curve for some of my data.

It's an sdf file containing a field marked 'Activity'. In this field, active compounds are marked '1' and inactives are marked '0'.

I want to use this field to generate the curve but so far i've been unsuccessful...

Can anyone shed some light on what I need to do?

Thanks in advance,

Christopher
