<DIV>Dear Gromacs Users!</DIV> <DIV>I have Isovaline in my Protein. It is not supported in the aminoacids.dat file. Can I simply call it VAL for the calculations or do I need to insert the data by hand. Is there any routine described online that tells me what I have to change?</DIV> <DIV>Regards</DIV> <DIV>Alex </DIV><p>
