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

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....

Hi The files I'm trying to run through hclust etc have the following sizes are these sizes "normal" for the output from vsn ? MalVSN and typVSN are four slide experiments each with 12288 spot features YeastVSN is from one slide with 12288 features > object.size(MalVSN) [1] 984976 > object.size(typVSN) [1] 984976 > object.size(YeastVSN1) [1] 381904 each one returns the following message Error: cannot allocate vector of size 589776 Kb Unfortunately I'm not sure of the specifcations of the machine I'm running it from (Dec Alpha) and my systems administration group aren't forthcoming apologies if this doesn't help much Thanks for everyones help Jason On Fri, 21 Mar 2003, Laurent Gautier wrote: >and also the amount of RAM your machine has....> > > TypVSNdist <- dist(typVSN, method = "euclidean", diag = FALSE, upper = > > FALSE) > > Error: cannot allocate vector of size 589776 Kb > > > typVSNcluster <- hclust(dist(typVSN@h))

With 10^4 genes the distance matrix (which needs to be calculated as an intermediate step by hclust) has size of 10^8, which corresponds to roughly 1 Gigabyte. I would not expect that all 12488 rows of your data carry relevant information, esp. if you have only 4 conditions. Also, it could be hard to display the cluster carpet or heatmap with more than a few hundred rows since your display may not have that many pixels. Best regards Wolfgang

Hi Jason, How big is your data matrix?
