Dear Bioconductor community,

  I was wondering if anyone could give me hint to where I can find pd.mirna.4.1 for affymetrix miRNA4.1 (array plate platform) microarray chip to read .cel files? Currently I can only find pd.mirna.4.0 (single chip array platform) on bioconductor.

Alternatively I would be happy if anyone has .pgf and .clf files which I could use in combination with the PDInfoBuilder library to generate a pd.mirna.4.1 database my own.

Many thx for your ideas!

cheers roland

You can get them from ThermoFisher. You want the library files for Expression Console and AGCC, not the ones for TAC.

With the .pgl and .clf files from the ThermoFisher link provided by James I've been able to create the desired pd.mirna.4.1 library :-)

# library("pd.mirna.4.1")

I have created the R package based on rolan.zauner's code. https://github.com/soumyabrataghosh/pd.mirna.4.1

Usage:

library(devtools)
install_github("soumyabrataghosh/pd.mirna.4.1")
