Hi,

I am using minfi 1.8.9

I loaded a matrix of beta values into minfi and try to annotate to genome as follows:

tmp = RatioSet(Beta = BMtrx)
annotation(tmp) = annotation(MsetEx)
tmp2 = mapToGenome(tmp)

I got the following error which indicates that an argument is missed in the function:

Error in .local(object, ...) :
object does not contain 'CN' amongst assay slots

Any idea?

Thank you in advance

1. Make sure that everything has the same version by running biocValid() and see if it returns TRUE. 2. Check that the object is valid, by running validObject(tmp) If the problem still persists, send me the BMtrx offline and Ill have a look (its good enough to just get 2-4 columns of the matrix).

Thanks Kasper for the quick response. I checked that every thing has the same version and the object is valid.

Then I think I need a couple of columns of the beta matrix object, to be of any help.
