Generative Topographic Map
...rsion of package
I noticed the original MatLab Pckage is much better documented.
I had a look at the R demo code "gtm_demo" and found that variable Y is used in advanced of being created:
I wrote my own few lines as follows:
inDir <- "C:/Documents and Settings/Monville/Alanine Dipeptide/DBP1/DHA"
setwd(inDir)
T <- read.table("DHA_TNH.txt")
L <- 3
X <- matrix(nrow=nrow(T),ncol=3,byrow=TRUE)
MU <- matrix(nrow=round(nrow(T)/5), ncol=L)
for(i in 1:ncol(X)) {
for(j in 1:nrow(X)) {
X[j,i] <- RANDU()
}
}
for(i in 1:ncol(MU)) {

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 4 atom pair distances all along the trajectory from
the initial to the final conformation. Likewise they al...

WMTSA "wavCWTPeaks" : Error in if (time.start < times.range[1]) time.start <- times.range[1]
...olumns 1 and 3 have to be considered. It is the work trajectory of a molecule migrating between two equilibrium conformations.
The curve has 2 peaks, as shown in its plot. But I keep missing the 2nd one. Here is my short script:

remove quotes from matrix
Hi all;
I have data at 734*22 dimensions with rows and columns names are
non-numeric.When I convert this data into matrix then all values show up
with quotes. Then when I use
x1= noquotes(x) to remove the quotes from the matrix then non-numeric row
names remain all other values in matrix disappear.
Your help is greatly appreciated.
