deepblue_flank {DeepBlueR} | R Documentation

## flank

### Description

Create a set of genomic regions that flank the query regions. The original regions are removed from the query. Use the merge command to combine flanking regions with the original query.

### Usage

    deepblue_flank(query_id = NULL, start = NULL, length = NULL,
      use_strand = NULL, user_key = deepblue_options("user_key"))

### Arguments

`query_id` | - A string (Query ID)
`start` | - A int (Number of base pairs after the end of the region. Use a negative number to denote the number of base pairs before the start of the region.)
`length` | - A int (The new region length)
`use_strand` | - A boolean (Use the region column STRAND to define the region direction)
`user_key` | - A string (users token key)

### Value

id - A string (id of the new query)
