hai
Thanks for your immediate reply. I tried to modify the xconst()
subroutine in ene.f. (
http://archive.ambermd.org/200502/0316.html). I
want to keep restraint on X and Y axis and allow the Z axis to move. But job
got terminated by showing the message as follows
......................................................................................................................................
APPROXIMATING switch and d/dx switch using CUBIC SPLINE
INTERPOLATION

SANDER BOMB in subroutine nonbond_list

Here is my input...
imin=0,ntx=7,irest=1,
ntb=2,ntp=1,taup=0.2,pres0=1.0,
nstlim=25000,dt=0.002,
tempi=300.0,temp0=300.0,ntt=1,tautp=2.0,
ntc=2,ntf=2,
ntpr=100,ntwx=0,ntwe=0,
cut=10.0,iwrap=1,ntr = 1,restraint_wt = 10.0,restraintmask = ':1-2873'
...................................................................................................................................
Why this type errors coming? How can I solve this? Did I do any mistake
while modify the code for keeping restraint on box dimensions? If yes.
