Subject: AMBER: energy terms in hybrid REMD calculation

Dear Amber users,

I noticed that the energy terms in the output file of hybrid REMD calculation using Amber 10 is not consistent.
Etot seems to be the total energy of the whole system, while others are energies of the subsystem.
Is there anyway to obtain the potential energy of the whole system?
I post an example output here.

 NSTEP = 250 TIME(PS) = 15996.500 TEMP(K) = 291.50 PRESS = 0.0
 Etot = -77998.9667 EKtot = 17160.6506 EPtot = -1257.1525
 BOND = 43.2327 ANGLE = 128.4559 DIHED = 89.4886
 1-4 NB = 59.8044 1-4 EEL = 917.1875 VDWAALS = -58.4719
 EELEC = -1937.1081 EGB = -499.7417 RESTRAINT = 0.0000
 TEMP0 = 291.8300 REPNUM = 1 EXCHANGE# = 10190
