Brainarray CDF with oligopackage
... Hi, I have a dataset from mogene20st platform. I am able to use the oligo package and read the celfiles and get the annotations. I am unable to use the brainarray CDF to read the celfiles. I realized that it's not added in pdInfobuilder. I referred to other posts where the cdf has been Pdinfobuilder ...

Differential gene expression of time series RNAseq expermimnet with one cohort (diseased)
... Hi, I have a question related to the design of the experiment to perform differential gene expression. I have a RNAseq timeseries experiment of 468 samples at three different time points (T0, week12, week24) of only one cohort (diseased). I don't have two condition here but I have three timepoints o ...
