Dear Amber users,
I have run this code to constrain distances between atoms using Amber 7 and the restraints work well (in this case I want to constraint the distance between two atoms in four separate cases) However, when I use this same code in Amber 8 no restraints are found in my output file. Has there been a change in the input format? How should I format the distance constraints?
Thanks
Whitney
