Dear amber users,

I have a problem with my molecule. It's unfolding a lot after 6 stages of
heating to 300K.

Here the input file of Stage 6:

Stage 6 heating of ArsM 250 to
300K
 &cntrl

  imin=0, irest=1,
ntx=5,
  nstlim=10000,
dt=0.0005,
  ntc=2,
ntf=2,
  ntt=1,
tautp=1.0,
  tempi=250.0,
temp0=300.0,
  ntpr=50, ntwx=50,
ntxo=2,iwrap=0
  ntb=0,
igb=8,

cut=999.0,rgbmax=999.

Below 3 pictures of 3 different stages:

Is there anything you can suggest?
Thank you for your help.
