Hi, Is there Bioconductor software for the new Affy miRNA chip? Does someone have experience normalizing the Affy miRNA chip? Any suggestions?

Hi, Lana As far as I know, Bioconductor does not have a package for Affy miRNA chip yet. There is a package for Agilent miRNA chips (available from BioC 2.5) using rma for normalization. I would also be interested in any suggestions for nomarlization for Affy miRNA chips.

For what it's worth, I just built a cdf and probe package for the Affy miRNA chip that will be part of BioC2.5, and which should allow one to use the affy pipeline to analyze these data. That said, I highly doubt the canonical affy analysis (e.g., ReadAffy(), rma()) will be a reasonable thing to do, as this chip contains miRNA from 71 different species. I would imagine one would want to subset out those probesets that pertained to the species at hand before proceeding with analysis, and that is a non-trivial exercise. This post to the BioC listserv by Jenny Drnevich should be quite helpful in that endeavor: http://article.gmane.org/gmane.science.biology.informatics.conductor/1 9867/match=affybatch+probe Best, Jim Chao-Jen Wong wrote: > Hi, Lana > > As far as I know, Bioconductor does not have a package for Affy miRNA > chip yet.

James and all, I have asked Affymetrix to create a CDF for the human species on the miRNA chip. They have created this type of CDF for our custom arrays which we use all the time.

Dear Lana, Maybe you could use package xps, which I have updated to work with miRNAs, see: https://www.stat.math.ethz.ch/pipermail/bioconductor/2009-August/02914 4.html In case you have a custom CDF for the human miRNAs only you could in principle use this CDF file.

To follow up op on this: I also just got the data of my miRNA profiling experiment performed on Affy arrays. Upon request Manhong Dai and Fan Meng at the MBNI were so kind to 'remap' the miRNA probes last August to mirBASE version 13, both to genome loaction and fasta files, for human, mouse and rat. Please find the links below. Also note that last september mirBASE updated to version 14, so the remapping *might* not completely up to date (although I don't think human/mouse/rat are seriously affected). With these custom CDF it should be possible to read the data using ReadAffy(). Currently I am evaluating which normalization strategy would be best for these relatively small number of probesets. RMA may indeed be an good option, but I have read before on this list that VSN may also be a good normalization method (in the the discussion regarding the Agilent miRNA array [1-color]). http://article.gmane.org/gmane.science.biology.informatics.conductor/1 40 96 Regards, Guido ---------------------------------------------------------------------- -- -------- From: Manhong Dai Sent: Fri 21-8-2009 16:22 To: Groot, Philip de Cc: Hooiveld, Guido; Meng Fan Subject: mirbase custom CDF Hi, mirbase custom CDF is generated. http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/12. 0. 0/mirbaseg.asp is based on genome location, the files we used can be got by searching 'miRNAgff' in http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/12. 0. 0/version.html http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/12. 0. 0/mirbasef.asp is based on mirbase fasta files, which are the bottom three lines of http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/12. 0. 0/version.html Please let me know if you came across any problem.

All, Dr. de Groot has given me this link for CDF and annotation files: http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/12. 0.0/mirbaseg.asp I would like to note here that Agilent arrays contain >4 arrays on one chip, so the normalization may not need to be so stringent as with the single Affymetrix arrays. I have successfully used Agilant-MAD scaled normalizeBetweenArrays(x,method="scale") previously for Agilant data. Perhaps this will also work for the Affymetrix chips?

Rao and collaborators have looked at different methods. A Comparison of Normalization Techniques for MicroRNA Microarray Data http://www.bepress.com/sagmb/vol7/iss1/art22/ L. PS: quantile-based normalization is one step in RMA. I am not sure that the probe summarization method applies for miRNA (worth a look, but those a likely very short - I do not how many probes per miRNA are on the affy chip) Hooiveld, Guido wrote: > To follow up op on this: > > I also just got the data of my miRNA profiling experiment performed on > Affy arrays. > Upon request Manhong Dai and Fan Meng at the MBNI were so kind to > 'remap' the miRNA probes last August to mirBASE version 13, both to > genome loaction and fasta files, for human, mouse and rat.
