Hello,

For me, AutoDock is still a standard for local docking. For blind docking, the SwissDock (http://www.swissdock.ch) server is an excellent tool. It is anyhow very recommended to start with multiple docking engines/functions before selecting one and eventually put some constraints. No need to go for commercial products. You got plenty of free alternatives for academic research. Please have a look at http://click2drug.org for a complete list (with links) of docking softwares and not only.

Dear Rajendran,

I agree with Rezvan, but if you still want an extension, you can request the company extend your licence and give you one month free.

thank you my dear researchers. but the problem is once we used the trial further extension is not available for the same mac id and the internet.
