Any R based package to integrate GTF format gene annotation to GenomicRanges object? or make a .sqlite object then can be saved (saveFeatures) for future use? really need this tool for RNAseq data analysis. Thank you very much! -- output of sessionInfo(): library(GenomicFeatures) library(Rsamtools) commands used: makeTranscriptsDbfromUCSC saveFeatures("ensGene.sqlite") loadFeatures("ensGene.sqlite") -- Sent via the guest posting facility at bioconductor.org.

did you try a google search with "bioconductor import GTF" -- there are a few direct solutions including http://manuals.bioinformatics.ucr.edu/home/ht-seq#TOC-Parsing-Gene- Intergenic-Regions-Bas On Tue, Nov 29, 2011 at 2:05 PM, sunny [guest] <guest@bioconductor.org>wrote: > > Any R based package to integrate GTF format gene annotation to > GenomicRanges object? or make a .sqlite object then can be saved > (saveFeatures) for future use? > really need this tool for RNAseq data analysis.

Thanks! I also have an idea to do it.... wish it works... -----Original Message----- From: Vincent Carey [mailto:stvjc@channing.harvard.edu] Sent: Tue 11/29/2011 3:49 PM To: sunny [guest] Cc: bioconductor@r-project.org; Sunny Yu Liu Subject: Re: [BioC] Using GTF gene annotation to build a GemomicRanges Object did you try a google search with "bioconductor import GTF" -- there are a few direct solutions including http://manuals.bioinformatics.ucr.edu/home/ht-seq#TOC-Parsing-Gene- Intergenic-Regions-Bas On Tue, Nov 29, 2011 at 2:05 PM, sunny [guest] <guest@bioconductor.org>wrote: > > Any R based package to integrate GTF format gene annotation to > GenomicRanges object? or make a .sqlite object then can be saved > (saveFeatures) for future use? > really need this tool for RNAseq data analysis.

worthy to have a try... thanks! -----Original Message----- From: Michael Lawrence [mailto:lawrence.michael@gene.com] Sent: Tue 11/29/2011 6:08 PM To: Sunny Yu Liu Cc: Vincent Carey; bioconductor@r-project.org Subject: Re: [BioC] Using GTF gene annotation to build a GemomicRanges Object The rtracklayer package can parse GTF, via import(). Then you just pass the resulting pieces to makeTranscriptDb(). That latter part is not so trivial though. I recently made the inverse for GFF3, i.e., outputting a TranscriptDb as GFF3 (see asGFF in devel rtracklayer/GenomicFeatures). I could imagine a direct importer of GFF3 and BED to TranscriptDb. Recent improvements to rtracklayer should make this easy. Any takers?
