Dear All, I would be grateful if you could provide assistance with a problem I am experiencing using Bioconductor to analyse Affymetrics microarray data. I am using the package affylmGUI and have managed to reproduce volcano plots from both experimental and other test data which have probe set IDs. This is after normalisation and linear model fitting. However when I try to apply gene names the error below occurs. Error in text.default(fit$coef[topGenes],fit$lods[topGenes], labels=substring(genelist[topGenes, : zero length 'labels' The volcano plot is produced but with no labels. Also the TopTable does not contain gene names or functions. This occurs with data files from two different chips. I have just started analysing data using R and bioconductor and so have tried to work this problem but have unfortunately been unable to resolve the situation. I am using MacOSX Snow Leopard and would be grateful for any help.
