[BioC] Spot weights

[Jason Skelton]

Hi

could someone give me an example of how to use the spot quality (name.W)
option from marrayRaw, I have a marrayRaw object with name.W taken from a
flags column from genepix (gpr) files but I'm not sure how to use it to
discard data in subsequent normalisations.  The gpr files have either P
(pass), M (marginal) F (fail) OR 0,-50 and -100 respectively.

Can you do this in R as well as bioconductor ?
for data that isn't marrayRaw

cheers

Jason
