Function for reading exon intron and promoter structure from a given bed file

readTranscriptFeatures(location,remove.unusual=TRUE,
                              up.flank=1000,down.flank=1000,unique.prom=TRUE)

## S4 method for signature 'character'
readTranscriptFeatures(location, remove.unusual = TRUE,
  up.flank = 1000, down.flank = 1000, unique.prom = TRUE)

`location`	location of the bed file with 12 or more columns. The file can end in `.gz`, `.bz2`, `.xz`, or `.zip` and/or start with `http://` or `ftp://`. If the file is not compressed it can also start with `https://` or `ftps://`.
`remove.unusual`	remove the chromomesomes with unsual names, mainly random chromsomes etc
`up.flank`	up-stream from TSS to detect promoter boundaries
`down.flank`	down-stream from TSS to detect promoter boundaries
`unique.prom`	get only the unique promoters, promoter boundaries will not have a gene name if you set this option to be TRUE

a GRangesList containing locations of exon/intron/promoter/TSS

one bed track per file is only accepted, the bed files with multiple tracks will cause en error

my.bed12.file = system.file("extdata/chr21.refseq.hg19.bed", package = "genomation")
my.bed12.file
feats = readTranscriptFeatures(my.bed12.file) 
names(feats)
sapply(feats, head)
