[BioC] How to remove probes from Illumina data?

[Matt Ritchie]

Hi Alice,

You could try setting the 'probes' argument in createBeadSummaryData() - if
you set it to a vector containing IDs for the non-control bead types, you
should end up with summarised data for these beads only.

If this doesn't work for you, or if you tried something else in beadarray
that you thought should work, and it failed, please send us an example of
the code you ran so that we may fix whatever is wrong.

Best wishes, 

Matt
