Is package "dr" appropriate for reducing the dimensionality of molecules conformational space ?
I anticipate lacking of prior experience with dimensionality reduction problems.
Some scientists concerned with drug discovery performed several steered Molecular Dynamics simulations of the
alanine-dipeptide molecule dragged by a radial force from an equilibrium conformation to another different equilibrium conformation.
They sampled at regular intervals 7 dihedral angles, 5 bending angles, and

RMSE vs. RMSD
Hi R users
This is not related to R but general stats terms. I
f any one help me to figure out how they differ and when I need to use which
one, i will appreciate it.
I read several simulation studies and found that RMSE (Root Mean Square
Error) and RMSD (Root Mean Square Difference) appered to be used
interchangeablely. The formula for calculating for both RMSE and RMSD are,
to me, the

Mantel test for comparing two matrices
Hi everyone,
I have two matrices of 2000x2000 size. They consist of a measurement of
RMSD deviations of a protein structure. The basic question i want
to answer is the following: are there a significant differences between
the two matrices?
I aim to use the Mantel test. I don't really know if this is a good idea or
if there are better solutions for these mega matrices.
Thanks

Substitute "Object not found" with NA
Hi everybody,
I'm trying to create a script that picks a txt file with 2 columns of coordinates (depth and variable1) and automatically tries to fit several polynomial with the function nls().
After that, it creates a list of observed, predict, residuals and other, and then it calculates AIC, RMSD, MAD and R^2.
At the end of the script I create a series of vectors with MAD for all

regression output to latex
hello everybody
i was seeking a converter beetween R regression output (eg with
summary) and the conventional way to present regression output in
paper: every model as a vertical vector with \beta, t beetween
parenthesis below the first, and other statistics (R^2 etc) .
I've seen hmisc and xtable, and if I didn't miss something, they
don't include something like that.
Thank you

GUI commands to call for a protein from protein data bank
What I am trying to do is use GUI function, traitr, and to call for a pdb
file and save it and then display it. I want to call for it by taking it
from the user and then displaying it on the screen. I am having problems
with that. The line pdb <- read.pdb(""ProteinCode) where proteincode should
be the name of the protein, for example 1ly2, but it always ends up being
protein. My

Colour makes my life; but not my bwplot (panel.violin)
Using Trellis, am successfully setting up a number of panels (25) in which I
have two box and violin plots.
I would like to colour - one plot as RED and the other as BLUE (in each
panel). I can do that with the box plots, but the violin density areas just
take on one colour.
My basic call is as follows:

Trouble with ISOLINUX and IDE bus resets.
Hpa,
Dell ships a CD called Dell OpenManage Server Assistant that,
starting with version 8.0 released last November, is a Linux-based
bootable CD. It uses ISOLINUX to load a linux kernel/initrd combo to
start the system. From version 8.0 to 8.2 we use isolinux version 1.66.
Starting with version 8.3 we have upgraded to version 2.08. First of
all, I'd like to say thanks for your excellent

Boost Protein Expression by Codon Optimization
Dear Colleague,
Happy New Year!
As we know, codon preference among different species could be dramatically different. To enhance the expression level of a foreign protein in a particular expression system (E.coli, Yeast, Insect, or Mammalian cell), it is very important to adjust the codon frequency of the foreign protein to match that of the host expression system. One classic example is GFP

How activate routing beetween domain
When I use vif-route and network-route in the xen-unstable latest release, the script vif-route is executes when I create a new VM , isn''t it?
Well the row that begin with ''ip r ...'' that enable routing in Dom0 is not execute by my system when I use ''xm create -c ...''. Are there errors in the script? If I invoke it directly, nothing happens.

Sortable list with Ajax and delete function
Hi,
After looking without any luck at different places for a working demo for sortable lists I created one. Simple lists are not a problem but lists that looks like a tree seems more complicated.
As demo you can have a look at:

focus problems
Hi!
I have some focus problems with wine if I use the managed mode.
When I start the application it has focus. But if I switch to another window,
and back, then the window gets its focus (the window decorations shows it),
but the windows app does not get it. If I click somewhere in the window, then
it gets the focus properly, but before that even the shortcuts does not work.

Best HMM package to generate random (protein) sequences?
Dear All,
I would like to generate random protein sequences using a HMM model.
Has anybody done that before, or would you have any idea which package
is likely to be best for that?
The important facts are that the HMM will be fitted on ~3 million
sequential observations, with 20 different states (one for each amino
acid). I guess that 2-5 hidden states should be enough, and an order
of 3 would

GO & Protein Complex Analysis for Homo sapiens
Dear All,
I need to fetch GO ontologies for Homo sapiens with their mappings to
corresponding Uniprot identifiers. I would be using this information to
compare result from a clustering algorithm with existing protein complexes.
This would be a test to check how the clustering algorithm accurately
captures GO terms with respect to the known protein complexes. Can anyone

is wine's ASPI suitable for firmware update?
Hi,
I have a PHILIPS CD-RW/DVD-ROM SCB5265 and I have problems reading of some
DVDs. I found two different firmware updates which contains .exe files:
TD17 (5/1/2007): http://ftp.us.dell.com/rmsd/PHILIPS-SCB5265-TD17.zip
TD19 (12/13/2005): http://ftp.us.dell.com/rmsd/SCB5265_fwTD19.zip
If I set up the IDE SCSI emulation, the firmware updater can recognize my
