Hi, i'm new to MD simulation, and i was stucked at the step of preparing ligand topology.

i have to change to file type of my ligand from (.mol2) to (.str). However, i couldn't perform that step because i cannot register and activate my account in CGenFF website. I didn't receive any email notification order to activate my account. Regarding this, how can i generate the .str file type other than CGenFF? Anyone have any idea please kindly help me. Thanks in advance.
