[BioC] Using GTF gene annotation to build a GemomicRanges Object

[sunny [guest]]

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")
