Hi I'm not involved with the conumee team but I had the same issue so I'm taking the liberty to answer. In my case, I had to select the probes that were in both the controls and the sample to analyse using:
anno@probes<- anno@probes[(anno@probes@ranges@NAMES %in% rownames(c.data@intensity)) & (anno@probes@ranges@NAMES %in% rownames(d.data@intensity))]
with c.data beeing the controls adter cnv.load and d.data being my sample.
I hope it helps
Thanks for your answer related to cnv.fit. I have been trying to run conumee2.0 with EPICv2 without any success. With you suggestion, I am able to create cnv.fit but it fails in cnv.segment. The error is : Error in if (min(weights) <= 0) stop("all weights should be positive") : missing value where TRUE/FALSE needed
My assumption is eventhough we are subsetting the probes in annotation object by matching probes from control set and data but actual bins which are created while constructing the annotation remain same.
So is there any way I change the bin in annotation object for EPICv2 matching both control and data.
Please suggest, Thanks.
Indeed this is my mistake, subsetting the probes is problematic. apparently, an updated version of the conumee vignette should come out very shortly, hopefully it will make it clearer
I created a MSet combining EPICv2 with EPICv1 and/or 450K. I created different annotation using CNV.create_anno with different array types - "EPICv2"/"EPIC"/"450k"/"overlap" The overlap options seem to be valid for overlap between EPIC and 450K only.
Whenever I run CNV.fit, it just shows this error:
Error in .local(query, ref, anno, ...) : query intensities not given for all probes.
Any step-by-step tutorial how I can get rid of this as an end-user? Thanks.
Best Regards, Max
