## Get gene sequence using the biomaRt package

### Description

Get gene sequence using the biomaRt package

### Usage

    getGeneSeq(LocationParameters, mart)

### Arguments

`LocationParameters` | c(ensembl_gene_id, distance from the peak to the transcription start site of the gene with the above ensemblID, upstream offset from the peak, downstream offset from the peak, Gene Start, Gene End)
`mart` | see useMart of bioMaRt package for details

### Value

a list with the following items

`feature_id` | ensemble gene ID
`distancetoFeature` | distance from the peak to the transcriptionstart site of the gene with the above ensembl gene ID
`upstream` | upstream offset from the peakStart
`downstream` | downstream offset from the peakEnd
`seq` | sequence obtained around the peak with above upstream and downstream offset
