I use redhat linux myself so I don't know much about the mandrake distribution. I would suggest first following Laurent's advice and make sure that the readline libs are installed on your system. As Laurent also comments nothing in bioconductor is dependent on hexbin. But this will soon change and hexagons will rule the world, na just kidding. If installing readline and readline_devel doesn't help email again and i will see if we can't get this debugged.

Iin general, am very impressed with the noise reduction using affy and truly appreciate the Bioconductor open source concept and packages available. I am trying to compare directly our own homebrewed data normalization within Splus (splining of affyIDs (post MAS summing of probes)) with the rma output. Question 1: Are the values output by rma to eset (and written to tab delimited file with write.exprs) the logbase2 of the "actual" affyID values, or are they the affyID values themselves. This is obviously important for comparing rma to our old methods, and for estimates of "accurate" fold change estimates- It seems to me that rma is much more precise in that much of the noise between replicates, especially at the low end, seeems to have been reduced in rma, but I am struggling with how to estimate back to accurate fold change estimates. Question 2: Is there an easy way to write out the PM values to tab delimited file post background correction and normalization (to assess individual probe sets prior to median polish). I am trying to work out reasons for differences between our old method and rma for individual affy IDs.

Working in log base 2 you could take differences and then take 2^(difference) to get fold changes. Or you could just take 2^(rma expression value) and take ratios if you prefer. You might find that RMA estimated fold changes are attenuated compared to other methods. That is that the estimated fold change is smaller than that computed using other methods. But the noise reduction at the low end is pretty dramatic. > Question 2: Is there an easy way to write out the PM values to tab delimited file post background correction and normalization (to assess individual probe sets prior to median polish). I am trying to work out reasons for differences between our old method and rma for individual affy IDs. If you manually background correct and normalize (as individual steps), doing something like data <- ReadAffy() data.bg <- bg.correct.rma(data) data.norm.bg <- normalize(data,method="quantiles") in each case pmdata.bg) and pmdata.norm.bg) will give pm matrices after preprocessing. Investigate the function write.table() for outputting the data to tab delimited files. thanks, Ben ------------------------------ Message: 4 Date: Thu, 20 Mar 2003 18:16:38 +0000 (GMT) From: Jason Skelton <jps@sanger.ac.uk> Subject: [BioC] mva functions To: bioconductor@stat.math.ethz.ch Message-ID: <pine.osf.4.44.0303201809270.138580-100000@pfes1.internal.sanger.ac.uk> Content-Type: TEXT/PLAIN; charset=US-ASCII I'm trying to use the mva functions dist & hclust however after a while I get the following message: TypVSNdist <- dist(typVSN, method = "euclidean", diag = FALSE, upper = FALSE) Error: cannot allocate vector of size 589776 Kb > typVSNcluster <- hclust(dist(typVSN@h)) Error: cannot allocate vector of size 589776 Kb I'm running R in linux, any help much appreciated regards Jason ------------------------------ Message: 5 Date: Fri, 21 Mar 2003 03:29:33 +0100 From: Laurent Gautier <laurent@cbs.dtu.dk> Subject: Re: [BioC] mva functions To: Jason Skelton <jps@sanger.ac.uk> Cc: bioconductor@stat.math.ethz.ch Message-ID: <20030321022933.GB7797941@genome.cbs.dtu.dk> Content-Type: text/plain; charset=us-ascii Dear Jason, We would need to know a bit more about your settings, like what one get by doing 'dim(typVSN)' or 'object.size(typVSN)', and also the amount of RAM your machine has....
