Dear list,
I find that I cannot normalize one (of several) NimbleGen files in
R-2.7.0
(using the preprocess() function of package Ringo), while I did
normalize
this dataset successfully before with R-2.5.0. I guess this is not
even a
problem of Ringo, but rather of normalizeWithinArrays (and thus of
limma),
or ?
Here is what I get with R.2.7.0 (and also with R.6.0, not shown):
> test <- readNimblegen("TFL2HA.txt", "spottypes.txt", path=dir[[2]])
