CCL: Calculation of PES

 Sent to CCL by: "Perumal  Gurusamy" [gurusamy2k5-#-yahoo.com]
 Dear CCLers,
 Greetings!
 I'm very new to this area. I'm Interested in studying the conformational aspects
 of various amino acids and need to plot PES. I'm facing problem in constructing
 a PES. Could anyone explain me the procedures of getting a PES on G-98/G-View or
 other free softwares. Any Tutorials/PPTs/PDFs will be of much useful.
 Thanking you for your help and i promise that i will summarise at the end.
 Regards,
 P.Gurusamy,
