Evaluation licenses are issued for a 30-day period. During your evaluation, you are allowed to use Lead Finder in your virtual screening, docking or binding energy estimation experiments in a test environment only to assess Lead Finder's performance on your data sets and to evaluate its fitness for your needs. If you want to use data obtained through experimentation with Lead Finder during your trial in your real practice or production environment, you need to acquire a standard license. There is a variety of license models available, including the utility-type (pay-per-use) model.
