Changing the file extension isn't a good idea. In your case, the argument
'textType' in readIllumina needs to be changed to ".txt" rather than ".csv"
as the raw data from the scanner is stored in tab delimited text files. So
BLdata <- readIllumina(textType=".txt")
and take a look at the readIllumina help page (?readIllumina) to find out
more about 'textType' and the other arguments in readIllumina.
