i had a look into the source and compared sander7 to pmemd 3.1. i got
the impression that the only thing needed to get it running is to remove
the initial test (if ntp=2 print that it is not supported) in
mdin_ctrl_dat.f90, since ALL code that it is sander7 source (runmd.f,
step 7, ~line 1365) is present in pmemd 3.1 (runmd.f90, step 7, ~line
713). there are all the tests whether ntp .eq. 1 or ntp .gt. 1...

so could it be, that the feature was just disabled in pmemd for
compatibility reasons, but in fact is in the source "waiting to be
uncommented"?
i'm not fortran programmer, so i may be wrong, but all the code
indicates to me that i might be right :)
thanks for your help. regards,
