thank you sir
I will use the recent version of vmd now. i was using vmd 1.8.5 right
now. do you think even this version would create problems?I am asking
this because if this is not the case, then i have to look into the
xleap built structure as according to me, there is nothing wrong with
th dipeptide
thanks
