Hi,     I want to use segChrom() method in tilingArray package. For that I need to create a probeAnno object. I could not find much much info by ?probeAnno. I need help in creating  probeAnno object.

I'm trying to read some web tables directly into R. These are both genome sequencing projects (eukaryotes and metagenomes) from NCBI and look very similar; however, only the first one works. http://www.ncbi.nlm.nih.gov/genomes/leuks.cgi http://www.ncbi.nlm.nih.gov/genomes/lenvs.cgi I added ?dump=selected to the end of the url string to get a tab- delimited file (which is what happens if you click the Save butto...

Genome Institute of Singapore (GIS) Biostatistics Group The Genome Institute of Singapore ( http://www.gis.a-star.edu.sg <http://www.gis.a-star.edu.sg> ) is looking for statisticians who are interested in a wide range of biomedical probems. We are especially interested in hearing from senior researchers interested in leading their own group. The institute is well-funded and engaged

Por si es de interés: Data Analysis for Genomics Data Analysis for Genomics will teach students how to harness the wealth of genomics data arising from new technologies, such as microarrays and next generation sequencing, in order to answer biological questions, both for basic cell biology and clinical applications. https://www.edx.org/course/harvardx/harvardx-ph525x-data-analysis-genomics-1401

Hi, is there any package/function in Bioconductor that can do this: if given the chromosome positions of a fragment, find out all genes within, and with the information about which strand is the sense strand. And vice versa. Thanks a lot. ----- Appreciate your time & attention! -- View this message in context: http://www.nabble.com/list-genes-w-n-a-genomic-fragment-tp18331452p18331452.html

Hello, I am using R to look at whole-genome gene expression data. This means about 27,000 genes, each with a vector of numbers reflecting expression at different tissues and times. I need to do an all against all co-expression calculation (basically, just calculate Pearson's r for every gene-gene pair). I try to store the result of such a thing in a 27000x27000 matrix, but r seems not to like

I wrote a package which includes a number of genome sequencing project statistics on the web like http://www.ncbi.nlm.nih.gov/genomes/lproks.cgi. I included some generic functions to summarize, plot, and update the tables with the most recent version data(lproks) update(lproks) [1] "lproks successfully updated, 7 new genomes added" I usually save the dataset back to my package data directory... save(lproks, fi...

Hello, I have a data frame (68,000 rows) of scores (V4) for a series of [genomic] coordinates ranges (V2 to V3). I also have a data frame (1.2 million rows) of single [genomic] coordinates. For each genomic coordinate (in coord), I would like to determine the average of all scores whose genomic ranges (in scores) encompass the coordinate (in coord). To accomplish this, I tried: The

Hi everybody, I am trying to make my mind about the use of R for Computational and Statistical Approaches to Genomics. I know this is a vaste field: this is the main reason why I am sending this message to this always useful list! Any key/entry point to this field will be extremely welcome! Please, could you help me to go in the right direction? Thanks!!! Ricardo -- Ricardo Rodr?guez

Great R people, I have noticed a strange behaviour in read.delim() and friends in the R 2.7.0 version. I will describe you the problem and also the solution I already found, just to be sure it is an expected behaviour and also to tell people, who may experience the same difficulty, a way to overcome it. And also to see if it is a proper behaviour or maybe a correction is needed. Here is the

Dear all: I installed the rsync 2.5.4 in my two machine (192.168.1.30 and 192.168.1.120, both are AIX OS) to backup data each other. The software`s installation is ok, and I can copy local files. But when I try to backup data between two machines, there reports some errors: >./bin/rsync -avz 192.168.1.30::web ./backup-3000/ rsync: failed to connect to 192.168.1.30: Connection refused

We are seeking a talented and driven postdoctoral fellow to join the laboratory of Jake Michaelson, PhD, assistant professor in the department of psychiatry at the University of Iowa. The Michaelson lab investigates the effect of genetic variation on the development and function of the brain, particularly in the context of neurodevelopmental conditions such as autism and language impairment. Our

Dear useRs, I am glad to announce that the new R package "hypred", initial version 0.1, is now available on CRAN. "hypred" is a package for simulating high-density SNP data. Its main function, "hypredRecombine" is intended to be used as a "Software tool" in larger programs that simulate complex populations. The focus of the package is on producing

I do have a bunch of genes ( nearly ~50000) from the whole genome, which read in genomic ranges A range(gene) can be seem as an observation has three columns chromosome, start and end, like that seqnames start end width strand gene1 chr1 1 5 5 + gene2 chr1 10 15 6 + gene3 chr1 12 17 6 + gene4 chr1 20 25 6 + gene5

...take as an argument, some aligned genome sequences, and using a sliding window, do pairwise comparisons of sequence similarity. Coding the sliding window I think I can manage but what I''m trying to get to grips with is getting it so as every pairwise comparison is made, no matter how many genomes are added, from 3 to N. So if I had four genome sequences, G1, G2, G3, G4 the comparisons would be: G1:G1 G1:G2 G1:G3 G1:G4 G2:G2 G2:G3 G2:G4 G3:G3 G3:G4 G4:G4 I can think of a way this might be done with a very complicated loop, which would take the region in the window of each genome and then...

Dear All, We have two computational biology positions to advertise - details below: Crispin ---- The Paterson Institute for Cancer Research (www.paterson.man.ac.uk<http://www.paterson.man.ac.uk/>), an Institute of The University of Manchester, seeks two (one senior, one junior) computational biologists to join the Applied Computational Biology and Bioinformatics Group (ACBBG).

Hi, I noticed some time ago that, for instance, named vectors that are really makes str() really slow when displaying the names attribute. I don't know exactly when this started, but it wasn't the case say 1-2 years ago. Example (on a WinXP 1.8GHz): > s <- 1:1000; names(s) <- s > system.time(str(s)) Named int [1:1000] 1 2 3 4 5 6 7 8 9 10 ... - attr(*, "names")=
