I have data exported from GenomeStudio (1.6) that I can correctly read and pre-process with lumi. However, when I try using read.ilmn in limma, I found that I get an error saying "Error in `rownames<-`(`*tmp*`, value = list(PROBE_ID = c("ILMN_1762337", : length of 'dimnames' [1] not equal to array extent." I have found that this was due to the inclusion of extra columns in my probe profiles (TargetID, ProbeID, SPECIES, SOURCE, TRANSCRIPT and on). When I removed them, I can correctly read the probe and control profiles with read.ilmn. Is there a better fix around this than manually removing the columns? -- output of sessionInfo(): R version 3.0.0 (2013-04-03) Platform: x86_64-apple-darwin10.8.0 (64-bit) locale: [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] parallel stats graphics grDevices utils datasets methods base other attached packages: [1] lumi_2.12.0 Biobase_2.20.0 BiocGenerics_0.6.0 limma_3.16.2 -- Sent via the guest posting facility at bioconductor.org.

Dear Josh, Could you please provide the command you used and also the first 10 lines of your probe profile file? The read.ilmn function allows any number of columns to be included in your data files. It just extracts those columns whose names match the names specified in the parameters. So I do not know what caused your problem unless I can have a look at your data.

Hi Chris, Please keep your posts on the list so you can get help from other people as well. There are more than one column in your data that have their column names containing the keyword 'Probe', however the read.ilmn function expect there is only one such column so that it can properly assign probe identifiers to the probes. It looks the first column of your data contains the probe identifiers, so you should set 'probe=PROBE_ID' when you run read.ilmn.
