How to create probeAnno object?
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.

reading tables from url
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 (w...

list genes w/n a genomic fragment
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

Very large matrices for very large genome
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...

how to save an updated dataset
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"...

vectorization with subset?
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

Unexpected behaviour in reading genomic coordinate files of R-2.7.0
...loosing strand information was to manually substitute an "R" to "-" and an "F" to "+" in the file before reading it in R. But it is much more cumbersome since the use of + and - is, for example, a standard format in bed files accepted and generated by the Genome Browser and other genome sites. Please let me know what do you think. Ps. I saw this first in the Fedora version (rpm automatically updated), but it is reproduced also in the Windows version. Thank you all people for your work and for making R the wonderful tool it is! Cheers, Margherita --...

questions about "connection refused"
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

Postdoctoral researcher: genome informatics in psychiatry
...haelson 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 work revolves mostly around integrating information from large scale data sets (e.g., whole genome sequencing, RNA-seq, ChIP-seq, etc.) and deriving informative features so that predictive models can be built and used to better understand the molecular basis of neurodevelopmental conditions. This postdoctoral position will be devoted mostly to developing models that estimate the downstream effe...

Pairwise Comparrisons
Dear all, I''m trying to write a function, that will 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...

str() with attr(*, "names") is extremely slow for long vectors
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")=
