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.

Dear Kavitha, I'm unaware of P/A calls at the transcript level. Could you please point me to some references so I can add it to my TODO list and future versions of oligo? At this moment, you get calls at the probe and probeset (as defined in the PGF file) levels: da1 = paCalls(<obj>, 'DABG') da2 = paCalls(<obj>, 'PSDABG') probes = pm(<obj>, level='probeset') probesets = rma(<obj>, level='probeset') dim(da1) dim(probes) dim(probeset) dim(da2) And, you're correct, MAS5 isn't defined for Gene ST arrays. benilton 2014-08-07 16:17 GMT-03:00 Mukund, Kavitha <kmukund@ucsd.edu>: > 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?

Dear Kavitha, Alternatively, you could use package xps, which does allow you to make P/A calls at both probeset and transcript levels for Mouse gene ST 1.0 arrays, see function dabg.call(). In addition, package xps has implemented MAS5 in a way that does also support whole genome and exon arrays, see function mas5().
