I encountered the same issue and it seems that the error occurs if scan date and decode date are not read successfully (or are missing) from the idat-file. For my analysis, I solved the problem by overwriting the readIdatFiles-function, inserting the following code before the line "dates$decode[i] = G$RunInfo[1, 1]" if(dim(G$RunInfo)[1]<2){ G$RunInfo<-rbind(G$RunInfo,matrix(c("1/1/2014 12:00:00 PM",NA,NA,NA,NA),ncol=5)) G$RunInfo<-rbind(G$RunInfo,matrix(c("1/1/2014 12:00:00 PM",NA,NA,NA,NA),ncol=5)) } "1/1/2014 12:00:00 PM" is a dummy date to make the function work. If you know the actual scan and decode dates, you can enter the correct values. Then you can use the updated readIdatFiles-function to obtain an NChannelSet object with red/green intensities. These you can convert to XY using the function RGtoXY (you'll have to copy all functions and variables used by this function to the global environment for it to work (use getAnywhere() to retrieve the code). For the crlmm environment variable, just use the new.env() function to create an empty environment). After that, you can call the genotype.Illumina function adding XY=XY (XY is the object you obtained calling RGtoXY). I know that this is a quite dirty hack, but it worked for me. Best, M
