Dear Amber users,
I want to do a energy minimization in vacuo using a distance-dependent
dielectric constant to mimic bulk solvent effects.
When I run Sander for doing energy minimization, it gives me the following
error message :
$AMBERHOME/exe/sander -O -i dna_vac_min.in -o dna_vac_min.out -c
dna_charges_cio.inpcrd -p dna_charges_cio.prmtop -r a-dna_vac_min.rst

My input file for Sander is given below :
dna in vacuo
&cntrl
imin=1,
maxcyc=700,
ncyc=200,
ntb=0,
igb=0,
cut=12,
dielc=1,
eedmeth=5

Could you please tell me how to do a energy minimization in vacuum using
distance dependent dielectric constant ? What are the parameters to be
included to do this ?
Thanks,
Lakshmi
