Hi George, What version of Chimera are you running? This problem: (DE3) dyld: Library not loaded: /usr/local/lib/libquadmath.0.dylib should be fixed in the 1.11 releases of Chimera. —Eric Eric Pettersen UCSF Computer Graphics Lab

I’ve loaded the prmtop and inpcrd of a protein in complex with a ligand (named DE3). I’ve tried to add ions to the complex using the Amber Tool.
I received the following message (see Reply log below). I wonder if I erred, in which case I would be grateful for any suggestions, or there’s a bug in the program.
Many thanks in advance
George
