Dear Amber users,

Again i got the same error of "segmentation fault" even whatever i modified
my batch-file. The "ndm_md1.rst" was not even created.

I compared the "ndm_md1.out" with other successful runs (i.e other
"xx_md1.out"), i found that the process of running wat-md1.in was halted in
the first step, as shown below (this is extracted from the "ndm_md1.out"):

*NSTEP = 0 TIME(PS) = 0.000 TEMP(K) = 0.00 PRESS =
0.0
 Etot = -64769.2683 EKtot = 0.0000 EPtot =
-64769.2683
 BOND = 79.7941 ANGLE = 500.8945 DIHED =
1498.9190
 1-4 NB = 453.3799 1-4 EEL = 7256.7348 VDWAALS =
10279.1689
 EELEC = -84838.1594 EHBOND = 0.0000 RESTRAINT =
0.0000
 Ewald error estimate: 0.8471E-04
 ------------------------------------------------------------------------------

Please help. I really have no idea what is going on. I think the
"ndm_md1.rst" had not been created because the process stopped unexpectedly.

Thank you.
Chinsu
