What is the meaning of the statement:

 -MCCI- BASED ON OPTIMIZED ORBITALS

In the context of doing a state averaged MCSCF calculation with GAMESS?

Thanks.

Dear all,

I have used GRID ver. 22 to calculate the MIF. I found that many of the
values given by *.kont is ZERO for certain grid. I don't know if I
should discard those value when I try to analysis the MIF using a
third-party statistic software.

Would anyone here like to give me some information about the range of
the value of MIF?

Any suggestions and/or comments will be really appreciated.

Thanks in advance!

Best wishes,

Jinsong

Frank,

Thank you for the suggestion. I've written a python script which automatically 
restarts the calculation if one fails. Much better now ;).

I put KDIAG=2 in the template and next time it fails the modified input will go 
to work. I will inform you immediately as it is clear. Up to now the longest run 
  has been 179 steps and the shortest one -- just only 2.

Should I try both 2 and 3?
I have checked INPUT.DOC and the description is not too clear.

And about the routine. So it is bugged then, isn't it?
Will you tell Mike about this?
Could it be fixed in the next release of GAMESS?

Thank you for your help.
Best regards.

	---Dmitry.

Dear CCLers'
I would like to know what is the best way to evaluate the stability of
radical cation and anion.
Thank you very much for your kind advices in advance.
Have a good day!

It seems you are requesting two processors for your job but your mpi 
configuration only reports one as being available. If you are using mpich, 
you could add the following option to your mpirun argument

mpirun  -np N  -machinefile my_machinefile  ./program

N = no. of processors (in yourcase 2)
my_machinefile = machinefile list  e.g.

pobox.com:2


Two in here means that server (pobox.com) has two processors

Hope this helps.

Dear CClers'
I have created electrostatic potential maps using the cube-generator in
Gaussian. I would like to know what units the resulting potential is in
either eV or kcal/mol.
I would greatly appreciate it if you would kindly give me an answer to
that.
Thank you very much for your kind attention all the time.
Have a good day!

... look for lanthanide compounds, where partially filled 4f levels should

Hello All!

The already traditional Winter School in Theoretical Chemistry will take
place in December, the week of Monday 13th to Friday 17th, 2004.

Venue: University of Helsinki, Finland
Topic: A Frontier of Chemistry: New Species
Level: Post-graduate and research, for scientists already involved in
       computational quantum chemistry

Speakers at this year's School include:
Lester Andrews
Karl Christe
Margaret-Jane Crawford
Laura Gagliardi
Michael C. L. Gerry
Martin Head-Gordon
Thomas M. Klapvtke
Markku Rdsdnen
Konrad Seppelt
Lai-Sheng Wang
Vivian Wing-Wah Yam

The School is free of charge for academics, but registration is required.
The registration dead-line is November 15th. Attendance is limited by
space restrictions imposed by the lecture hall.

This year, attendees are encouraged to submit a poster abstract; a proper
poster session is now part of the School!

For more info, have a look at the web page of the School:

See you in Helsinki in December,

Here are the two answers I got. Thank Dirk and Jeff
again.

A co-worker made his PhD-Thesis on conformational
analysis of (cyclic) 
peptids, but its in German:
http://diss.ub.uni-duesseldorf.de/ebib/diss/show?dissid=150

Regards, Dirk.

A 21 residue peptide would not be tractable to a
systematic search.  Monte Carlo and/or
high-temperature molecular dynamics are your best
bets.  To get started with some ideas, you may want to
take a look at the following: 

1.  Prabhu NV, Siddiqui SA, McMurray JS, Pettitt BM.
2001. Structural basis for the activity of pp60c-src
protein tyrosine kinase inhibitors. Biopolymers 59:
167 
2.  Levy Y, Becker OM. 2001. Energy landscapes of
conformationally constrained peptides. J. Chem. Phys.
114: 993 
3.  Worth GA, Nardi F, Wade RC. 1998. Use of multiple
molecular dynamics trajectories to study biomolecules
in solution: The YTGP peptide. J Phys Chem B 102: 6260


There are many other examples in the literature.
