Dear Robert,
Gabedit can simulate a NMR spectrum using the chemical shift and the
spin-spin coupling
parameters calculated by Gaussian (or any other computation chemistry
packages).
The simulated NMR spectrum can be compared to the experimental spectrum
(read from a jdx or a jMRUI file format).
After simulation, you can save the curve in a txt file (2 columns).
Gabedit is a free open source.
You can download it from : http://gabedit.sourceforge.net
Best regards,
A.R. Allouche

Dear All,
During the calculation of binding free energy i got negative entropic
contribution (NMODE= negative). Can entropic contributions be negative, and
what is the significance of it?
Every help is welcome. Thanks in advance.

Dear All,
i'm trying to figure out scheme for calculating protein amino acid clashes. I've read that
1) The overlap between two atoms is defined as the sum of their VDW radii minus the distance between them and minus an allowance for potentially hydrogen-bonded pairs:
overlapij = rVDWi + rVDWj dij allowanceij
vdw_C = 1.70
vdw_N = 1.55
vdw_O = 1.52
vdw_P = 1.80
vdw_S = 1.80
allowanceij=0.4 (taken from "Penultimate rotamer library")
i calculated rotamer clashes from "Penultimate rotamer library" according to 1) for 1st D rotamer:
0 N ASP 1 -1.458 0.000 0.000
1 CA ASP 1 0.000 0.000 0.000
2 C ASP 1 0.551 -1.198 -0.766
3 CB ASP 1 0.536 0.000 1.433
4 CG ASP 1 0.292 1.315 2.147
5 OD1 ASP 1 -0.027 2.312 1.464
6 OD2 ASP 1 0.419 1.350 3.388
i got the following clashes
column 3 - first atom
column 4 - second atom
column 2 - vdw_radius_first_atom+vdw_radius_second_atom
column 1 - distance between first and second atom
1 2 3 4
residue=1 has clash=2.461309 3.250000 0 2
residue=1 has clash=2.455509 3.250000 0 3
residue=1 has clash=3.066159 3.250000 0 4
residue=1 has clash=2.534580 3.400000 1 4
residue=1 has clash=2.736671 3.220000 1 5
residue=1 has clash=2.504202 3.400000 2 3
residue=1 has clash=2.379763 3.220000 3 5
residue=1 has clash=2.378700 3.220000 3 6
residue=1 has clash=1.249904 3.220000 4 5
residue=1 has clash=1.247972 3.220000 4 6
residue=1 has clash=2.196847 3.040000 5 6
i'm sure i do something wrong because "Penultimate rotamer library" was checked for the clashes.
could someone pleaseeeee help me with figuring out the correct procedure
many thanks
Tania

Hi Radek,
If you want to try with Zinc parameters developed for a similar system
you could use these included in Mori M., et al, Journal of Chemical
Information and Modeling, ASAP paper...
I developed a forcefield for a zinc-binding motif constituted by an
histidine and three cysteines (one N and three S coordinating atoms).
Hope this help
regards
mattia
PS: in any case you could check the AMBER mailing list for more info...

Tania's question was already answered on the chimera-users]|[cgl.ucsf.edu mailing list, see
http://www.cgl.ucsf.edu/pipermail/chimera-users/2010-April/005007.html
To summarize, she should be using the option in Chimera's
Find Clashes/Contacts tool to ignore pairs of atoms
that are directly bonded or separated by only a few bonds.
That option is on by default. The bonded atoms are often
closer together than would be expected from their VDW radii
alone, and if that option is turned off, those pairs will often
be identified as clashing even though they are not really clashes.

Hi
Does anyone have experience of Molrpo calculations on GridChem? My jobs
sometimes stopped abnormally with job status showing "Time Elapsed", but
sometimes, the same jobs can finish normally. I will be very appreciated
with your advices.
