add_seed {scsR} | R Documentation

## add_seed

### Description

This method takes in input a dataframe containing the results of an siRNA screen. This screen must contain the siRNA sequences in a dedicated column (the sequences have to be provided in the guide/antisense orientation). Then it adds a column with the seed of the siRNA sequences.

### Usage

    add_seed(df, seqColName="siRNA_seq", seedLength=7, startPosition=2)

### Arguments

`df` | Dataframe containing the results of the siRNA screen.
`seqColName` | character vector with the name of the column that contains the siRNA sequences (the sequences have to be provided in the guide/antisense orientation).
`seedLength` | length of the seed in nucleotides (by default 7 bases) (integer)
`startPosition` | position in the siRNA sequence where the seed starts (by default position 2) (integer))

### Value

screen data frame with the seed column added.
