### Description

Per group get the part upstream of position upstreamOfPerGroup(tx, startSites(cds, asGR = TRUE)) will return the 5' utrs per transcript, usually used for interesting parts of the transcripts.

### Usage

    upstreamOfPerGroup(tx, upstreamOf, allowOutside = TRUE)

### Arguments

`tx` | a `GRangesList`, usually of Transcripts to be changed
`upstreamOf` | a vector of integers, for each group in tx, where is the the base after the new stop point of last valid exon.
`allowOutside` | a logical (T), can upstreamOf extend outside range of tx, can set boundary as a false hit, so beware.

### Value

a GRangesList of upstream part
