In page number 255 amber manual 2020, it has been mentioned that value (under the figure number Figure 14.2) of Rmin of carbon is mentioned as 1.908 A. However, the image shows the value (in the plot) of Rmin is indicated at 3.8 A. The definition of Rmin, which they mentioned just above the image is that it is the sum of the vanderwaal radii of two atoms. If that is the case, the caption below the image should say Rmin=3.8 A. But it says, Rmin=1.908 A. Now my question what is the value of Rmin? is it 1.908 A or 3.8 A? Kindly clarify . Thanks in advance
The link for amber 2020 manual is, https://ambermd.org/doc12/Amber20.pdf
I have also attached the amber manual as well
The van der Waals radius (R) of carbon atom in AMBER force field is 1.908 A. The sum of the van der Waals radii of two carbon atoms, i and j, is: Rmin = Ri + Rj = 1.908 + 1.908 = 3.816 A.
Thanks ! Martin Klvana . I agree with you. Thanks a lot for the clarificiation
