I read Timtico's answer here.
And I wonder why not a universal format for expression data?
For every sample:
geneID mRNA quantity gene0 N0 gene1 N1 gene2 N2 ...
is what we really want to know.
If I understand it right, the coverage of mapping in RNASeq is the Ni. What about microarry data? Can we convert it into this format?
