Hi Neel, I think your problem with the filtering function, is not the filtering itself but when the function tries to write an output. I am modifying this, so the user can choose whether or not they want to have an output file in the filtering step. In the meantime, can you tell me what you have in? names(dd), names(dd$genes) names(dd$genes) names(dd$other) What version of the Extractor are you using? p.- De: Neel Aluru [mailto:naluru@whoi.edu] Enviado el: Wednesday, June 16, 2010 10:54 PM Para: Richard Friedman; Pedro López Romero; bio c bioconductor Asunto: Re: [BioC] AgiMicroRNA and Extra columns in Agilent Mouse miRNA Microarray Release 12.0 G4471A-021828. Hi Rich, Did you try filtering probes using FilterMicroRna function after removing the two columns. I am having difficulty in filtering probes. Thanks, Neel At 04:19 PM 6/16/2010, Richard Friedman wrote: Dear Pedro and List, My text files form Agilent Mouse miRNA Microarray Release 12.0 G4471A-021828 has two extra columns which are not in GSE19232 Agilent human microRNA array v 2.0 (G44708) - "start" and "sequence". When these are deleted AgiMicroRNA works. I do not know if this is due to the array or software or processing options on the software. This clears up the problem with maMicroRna( which i have been writing you about. It would be nice if this could be taken into automatically in a future version of AgiMicroRNA, but this solves my porblem for now.
