Dear CClers,
I would like to know if SCORE(for estimating the binding affinity of
protein-ligand complex)is still freely distributed and how to obtain it.
I wrote several times to the correspondents indicated in the SCORE web
page, but I got my emails back. 
 
Regards,
 
Maria Letizia

Rich,

Thank for your prompt and straight forward reply. However I am surprised 
that bugs leading to incorrect bond lengths when using Chem 3D as a 
Gaussian interface was not given higher priority three years and two 
versions ago.

I look forward to using version 8.

Sincerely,
Laurence Lavelle

<color><param>0100,0100,0100</param>Hi,


When we're performing oniom calcs, using G98, the calculation 
always crashes due to the fact that in the high-level part of the 
calculation the multiplicity doesn't equal the input value of 1. Looking 
at the output it seems that gaussian98 doesn't add the necessary 
terminating hydrogens.


Example we did a calculation on trifluoromethylsilane (CH3F3Si) 
wherein we treated the trifluoromethyl part on a medium (AM1) level 
whereas the rest of molecule was calculated on the High (DFT) 
level.

Hello CCL'ers,

In Insight II for all force fields except CFF, assignment of charges (and 
atom types) to each atom is done with the "Potentials" parameter block, 
which is accessed from the "FF" icon.  The Insight program assigns atom 
types and partial charges to each atom in the structure based on 
information in a residue library file (.rlb) if the residue is known or (if 
not found in a residue library file) from the bond increments found in the 
force field file based on the atom types.  The charge values present in the 
residue library file and the bond increments in the force field file
(.frc) are derived from experimental (usually crystallographic) data and 
quantum mechanical modelling.  The purpose of using a bond increment scheme 
for residues not in the residue library is that the local bonded 
environment (as described by the atom types) determines the atom centered 
charge.  The Gasteiger method first determines the overall charge of the 
system and then distributes that charge throughout the molecule (the 
Gasteiger method is available for use with Discover in Cerius2).  Note that 
CVFF was developed to reproduce peptide and protein properties.   The CFF 
force field has far greater support for highly funtionalized small molecules.
This information is available to all Accelrys users at 
http://www.accelrys.com/doc.

<font size=3>Hello CCL'ers,<br><br>
In Insight II for all force fields except CFF, assignment of charges (and
atom types) to each atom is done with the &quot;Potentials&quot;
parameter block, which is accessed from the &quot;FF&quot; icon.&nbsp;
The Insight program assigns atom types and partial charges to each atom
in the structure based on information in a residue library file (.rlb) if
the residue is known or (if not found in a residue library file) from the
bond increments found in the force field file based on the atom
types.&nbsp; The charge values present in the residue library file and
the bond increments in the force field file <br>
(.frc) are derived from experimental (usually crystallographic) data and
quantum mechanical modelling.&nbsp; The purpose of using a bond increment
scheme for residues not in the residue library is that the local bonded
environment (as described by the atom types) determines the atom centered
charge.&nbsp; The Gasteiger method first determines the overall charge of
the system and then distributes that charge throughout the molecule (the
Gasteiger method is available for use with Discover in Cerius2).&nbsp;
Note that CVFF was developed to reproduce peptide and protein
properties.&nbsp;&nbsp; The CFF force field has far greater support for
highly funtionalized small molecules.<br>

Dear CCL members,

I have a Gaussian 98 related question:

According to the g98 users manual (p. 155, TD keyword) it should be
possible to do Time Dependent DFT geometry optimizations of the N-th
excited state using the Root=N option. 

However, I canīt find a proper input. The easiest input line

 #P TD=(Root=1) B3LYP/STO-3G Test DENSITY OPT=Z-Matrix

leads to an error in link 1002:

 (Enter /vol/chemie/libexec/g98.A9/g98/l1002.exe)
 Minotr:  Closed-shell wavefunction.
 Cannot mix post-SCF and DFT.
 Error termination via Lnk1e in /vol/chemie/libexec/g98.A9/g98/l1002.exe.
 
I played around with several other options, tried to do the job in a two
step procedure, like it is described for the CIS method in
Forsman/Frischīs "Exploring Chemistry with Electronic Structure Methods",
all without success. Is it possible to do these calculations?  Anybody out
there with experience in this topic? The ultimate goal would be to perform
a normal mode frequency calculation for excited states within the TD-DFT
formalism. 

Regards, :-)ohannes.

Martijn Zwijnenburg inquired about the failure of an ONIOM calculation using
G98.  I just encountered the same problem with my first attempts at using
ONIOM.

I found that it was necessary to explicitly define the "replace-atom" in the
input file for those atoms which were at the boundary between higher and
lower levels.  The Gaussian manual states that defining a replace-atom is an
option, but this apparently is NOT the case.

So, Martijn, try modifying your input file to this:

%Chk=oniom_test
#P trackio
# opt ONIOM(B3LYP/sto-3g:AM1)
# NoSymm

That's an understandable expectation, but management had a different opinion on how to proceed with the development resources we had available at the time.  It was decided to put the resources available on implementing GAMESS and Tinker interfaces.  New development resources have become available, but it is still unclear as to when the issues you have reported will be addressed.  We do hope to address them in a future release.

Hi,
I am new to using CHARMM.  I made a water box and tried to combine the
waterbox pdb file with my protein pdb file using CHARMM and generate the
final psf file.  But I got the following error:

** ERROR IN SEQRDR ** REPEATED RESID FOR   391 1391 100

when it tried to read the sequence for my waterbox.  The RESID for my
water box starts from 1 and with a segment ID WATR.  There is no water
molecules in my protein pdb file.

CHARMM read in my protein pdb file without a problem.  Only when it got to
reading the water box.  I don't know why it says I have repeated RESID.

Any suggestion will be helpful. Thanks

Alice
