Hey Mark, thanks for the swift reply. I installed 4.0.5 now. with the same testset it failes this time on some of the kernel tests though all pdb2gmx ones pass. As far as I understood, I should simply ignore it? I didn't use --enable-mpi but when I run test script with -np 4, it does the job

2008-10-27 Thread Peyman Yamin
. both have the same charge (-0.421) and mass (15.9994). I guess the charge is reasonable for the double-bonded one, but not for the one with a single bond and a free electron. How could I correct this? Cheers, Peyman -- Peyman Yamin Lehrstuhl fuer Thermische Verfahrenstechnik Universitaet Erlangen
