DMS is the only program requested to generate DOCK input files I was not able to install. I read something similar in this same mailing list. The first problem I encountered was an error message referred to "radii" directory. Thus I created the radii directory and I put radii.proto file into it. Now the error message is "Unknown atom type N", and by eliminating N atoms from my input file the new error message is "Unknown atom type CA", and so on. It seems that the program is not able to recognize atoms with their atomic radii, thus I think that the problem is still in this file. Any suggestion?
