... Hi Pablo, The function "read.maimages" is no longer used by AgimicroRna. "read.maimages" creates an object of class RGList with element names: R, Rb, G, Gb, etc ..., that are proper for two-channel arrays. To make the names more intuitive for the analysis of microRna arrays, I have introduced some ...

... Hi, the cvArray function uses "which(duplicated(ddDUP$genes$ProbeName)==TRUE)" to get the duplicated Probes. If instead of having "ProbeName" you have "ProbeUID" the function is not going to work. The readMicroRnaAFE() uses read.maimages() from limma, and then we select what columns are retained in ...

... Hi all, I am using the microRNA Agilent platform to conduct a differential expression analysis. Does anyone know what are the processing protocol that is recommended by the Agilent manufacturer? I think that we should use the Total Gene Signal (TGS), but, does Agilent recommend any sort of normal ...
