Hello All,
I am trying to make P/A calls at both probeset and transcript levels
for Mouse gene ST 1.0 array using Oligo.
Here is what I did for probeset level P/A calls
mmNormal_ps <- rma(mmNormal_raw, target="probeset")
dabgPS <- paCalls(mmNormal_raw, "PSDABG")
ind <- apply(dabgPS, 1, function(x) sum(x < 0.01) > 5)
mm_ps <- mmNormal_ps[ind,]
But I have been unable to implement it at a transcript level, say,
mmNormal <- rma(mmNormal_raw, target="core") #transcript level
dim(mmNormal)
# Features 35556 Samples 12
Clearly, I can't do
dabg<- paCalls(mmNormal_raw, "DABG") #
Probe level
dim(dabg)
# 899636 12
And it doesn't work when I try and do
Mas5<- paCalls(mmNormal_raw, "MAS5") # I
guess because mmNormal_raw is a GeneFeatureSet object.
Can anyone tell me what I am missing when implementing transcript
level paCalls using Oligo? I have made P/A calls on affybatch objects
but haven't used oligo. Any help/pointers in this regard is much
appreciated.
Thank you in advance.
