hi all,

i have problem generating the psf of biotin. it says
there are some missing parameters in the file, and it
asks me to parameterize the molecule.
 
Does anybody have the topology/parameter files of biotin?
Also, does anybody have experience in generating the
unbinding of biotin from avidin complex simulation?

Thank you very much!

 Regards,
 Lavina
