Hi Nolwenn,
The crlmm package should be able to handle your 610k quad data.
You'll need idat files rather than bead-level text files to get started.
Take a look at the crlmmIllumina vignette for further information
BTW, the human610quadv1bCrlmm package is a chip-specific package which
contains parameters used internally by crlmm - it isn't really an
annotation package.
I hope this helps. Best wishes,
Matt
