I want to ask a question about the npopt thing,according to amber manual,when
NPOPT = 2 ,then RADIOPT should be 1,and this means using the radii
optimized by tan and luo,but there are no reference about that,can
anybody tell me
the exact name of that paper by tan and luo?
And i also want to know if the option NPOPT = 2 ,RADIOPT=1 cant be used when
dealing with protein and antechamber defined small molecule complex or not ?
because everytime i run MS=0,NPOPT=2,RADIOPT=1,it doesnt work,the result
shows missing surf data and stop at calculating the raw data?
thank you!
