Usage
usage: geninput.pl [options] options: [-d force res1:res2[=res1:res2 ...]] [-par random=val,ncycle=val,icycle=val, tsteps=val,resmin=val,resmax=val, temp=first[:last],softcore=val, central=val,stiff=val,pair=val, kdcore=val,hbond=val,short=val, burial=val,multibody=val,threebody=val] [-seq file]
Description
Generates an input file for MONSSTER.
Available parameters and their default values are shown
in the table below. The values can be overwritten by specifying
the parameter name and the new value with -par
Key | Explanation | Default |
random | random seed | random value |
ncycle | cycles/temp. step | 20 |
icycle | MC moves/cycle | 50 |
tsteps | temperature steps | 10 |
resmin | first fragment residue (fixed template) | 0 |
resmax | last fragment residue (fixed template) | 0 |
temp | temperature range | 2.5:1.0 |
softcore | soft core radius for large residues | 4.0 |
central | centrosymmetric potential scaling | 0.25 |
stiff | general stiffness potential scaling | 1.25 |
pair | pair potential scaling | 1.0 |
kdcore | hydrophobic core potential scaling | 0.35 |
hbond | H-bond cooperativity potential scaling | -0.3 |
short | short range potential scaling | 0.5 |
burial | burial potential scaling | 1.0 |
multibody | multi body potential scaling | 0.5 |
threebody | 3 body potential scaling | 0.25 |
Distance constraints between residues (e.g. if disulfide linkages are known) may be specified using -d with a force constant and a list of residue pairs as parameters. A MONSSTER sequence file may be given with -seq for translating the residue numbering accordingly.

Examples
geninput.pl
generates the default MONSSTER input file

geninput.pl -par ncycle=50,stiff=0.1 -d 5.0 10:34=19:26
generates a MONSSTER input file iwth 50 cycles per time step and a
modified scaling factor for the general stiffness potential term.
In addition sidechain restraints are specified between residues
10 and 34 as well as 19 and 26.
