Hi all,
I've already simulated 27 organic molecules in a cubic solvent box. Now
I would like to calculate the SAS of this system. I've a tpr and a trr
with only the molecules inside (without water).
I'm using gromacs 4.0.5.
I've added the box dimension infos to the trr using the command:
trjconv
Dear Dr. Wassenaar,
many thanks for your kind reply.

Hi all,
perhaps a silly question but i didn't find the correct way to calculate
the variance explained by each eigenvec in ED analysis.
Could someone point me out to a correct tool/option to use.
I'm using gmx v3.3.
Many thanks

Hi all,
I would like to have a txt file from an xpm matrix generated by g_rms or
g_cluster. Someone has already done this?
I've seen in the previous posts some hints about hacking the code or
scripts usefull for g_covar...but I'm not so confortable and expert to
do such things without a step by
Hi and thanks for answering to my previous question.
Now I'm calculating the rmsd between two trajectories (-f2 option).
One is made by 2200 frames and the other has 33 frames..Now I've some
doubt about the output (rmsd.xvg), cause this file has only two columns
with 2200 rows ...i was imaging
Hi,
You should be getting such a 2200x33 matrix. My guess is that the
command line or files that you're using are not what you think they
are :-)
my command line is
g_rms -f 2200.pdb -f2 33.pdb -s ref.pdb -n -o -m -bin
Note that the pdbs (traj and ref) have the same number of atoms (same
. So, which is the meaning of that value? a
mean of all the rmsd calculated for that frame in respect to the other 33 refs?
Thanks

So does the -Rmat option not produce a human-readable text file?
Hi, unfortunately I can't see this option in g_rms.
I'm using the v 3.3.1 and also on the reference page online there is not
-Rmat. Am i missing something?
Thanks

for a group for the LSfitting..could
someone explain me this behaviour?
Is my procedure correct for my purpose? Is normal that g_cluster does
not accept the -fit option?
Thanks

Hi all,
I've performed my MD simulations using the charmm FF and NAMD (so
pdb,psf and dcd files). Now i would like to use the great GMX analysis
tools. I've successfully converted the dcd file in trr (using catDCD).
Now the next step I'd like to do is the psf to top conversion. I've seen

Hi all gmxers,
I'm trying to analyze an amber dynamic (v.8) with the gromacs tools
(last version). Sorry in advance for the long message.
To do so, I'm trying to generate also a tpr file (needed by some tools).
My procedure is being to convert all the MD in multiple pdb format.
So I have extracted
Hi all,
I'm trying to simulate a system with two identical proteins (42aa each one),
solvent spc (18430 mols) and 6 ions NA+...for a total of ~56100 atoms.
Now the problem is that if I run the MD on 4 nodes everything works fine,
but when I try to use 6 or 8 cpus the process stops on the
Hi all gmx-ers,
I have a doubt concerning the REMD setup. Let's say I want to use 12 cpus to
make a REMD at 2 different temp 300 and 400K of the same system.
Should I prepare every tpr file with the -np option set to 6?
and then run the mdrun with -np 12 -multi -s 300.tpr 400.tpr -replica

Thanks to all for the quick clarifications.
