Hi, Ray

This time I set MS=0, radiopt=0, and npopt=1, but the job still can not pass.
and the log file of mm_pbsa.pl gives out "
=>> Creating input
    Sander input
    PBSA input

=>> Calculating energy / entropy contributions
    Calc contrib for ../01/thrombin_cda_wat_com.crd.1
        Calc MM/GB/SAS
 bad atom type: f
        /home2/handicp/wuling/amber9/amber9/exe/sander -O -i sander_com.in -o sander_com.1.out -c ../01/thrombin_cda_wat_com.crd.1 -p ../01/protein.prmtop not successful"

and the sander_com.1.out stop at "
Potential function:
     ntf = 1, ntb = 0, igb = 2, nsnb = 99999
     ipol = 0, gbsa = 1, iesp = 0
     dielc = 1.00000, cut = 999.00000, intdiel = 1.00000
     saltcon = 0.00000, offset = 0.09000, gbalpha= 0.80000
     gbbeta = 0.00000, gbgamma = 2.90912, surften = 1.00000
     rdt = 0.00000, rgbmax = 25.00000
     alpb = 0
     scnb = 2.00000, scee = 1.20000

Frozen or restrained atoms:
     ibelly = 0, ntr = 0

Energy minimization:
     maxcyc = 1, ncyc = 0, ntmin = 1
     dx0 = 0.01000, drms = 0.00010
"
how do I deal with it?
Thanks in advance!
