Package: BSgenome.Dmelanogaster.UCSC.dm6 Title: Full genome sequences for Drosophila melanogaster (UCSC version dm6) Description: Full genome sequences for Drosophila melanogaster (Fly) as provided by UCSC (dm6, Aug. 2014) and stored in Biostrings objects. Version: 1.4.2 Suggests: GenomicFeatures organism: Drosophila melanogaster common_name: Fly provider: UCSC provider_version: dm6 release_date: Aug. 2014 release_name: BDGP Release 6 + ISO1 MT source_url: http://hgdownload.cse.ucsc.edu/goldenPath/dm6/bigZips/ organism_biocview: Drosophila_melanogaster BSgenomeObjname: Dmelanogaster seqnames: seqnames(Seqinfo(genome="dm6")) circ_seqs: "chrM" SrcDataFiles: dm6.2bit from http://hgdownload.cse.ucsc.edu/goldenPath/dm6/bigZips/ PkgExamples: genome$chr2L # same as genome[["chr2L"]] . ## --------------------------------------------------------------------- ## Extract the upstream sequences ## --------------------------------------------------------------------- ## The upstream sequences can easily be extracted from the full genome ## sequences with something like: . library(GenomicFeatures) txdb <- makeTxDbFromUCSC("dm6", tablename="refGene") up1000seqs <- extractUpstreamSeqs(genome, txdb, width=1000) . ## IMPORTANT: Make sure you use a TxDb package (or TxDb object) that ## contains a gene model based on dm6 or on a compatible genome (i.e. ## a genome with sequences identical to the sequences in dm6). Note ## that you can make a TxDb object from various annotation resources. ## See the makeTxDbFromUCSC(), makeTxDbFromBiomart(), and ## makeTxDbFromGFF() functions in the GenomicFeatures package for more ## information. seqs_srcdir: /fh/fast/morgan_m/BioC/BSgenomeForge/srcdata/BSgenome.Dmelanogaster.UCSC.dm6/seqs seqfile_name: dm6.2bit
