GetInfProfile {QSutils} | R Documentation

## Information content profile of an alignment

### Description

GetInfProfile computes the information content at each position of an alignment.

### Usage

    GetInfProfile(seqs,nr=NULL)

### Arguments

`seqs` | DNAStringSet or AAStringSet with the haplotype alignment.
`nr` | An optional numeric vector with the haplotype counts to take into account the information content of each position in the alignment.

### Value

Returns a numeric vector whose length is equal to the length of the alignment. Each value corresponds to the information content of each position in the alignment.

### Examples

    # Load the alignment.
    filepath<-system.file("extdata","ToyData_10_50_1000.fna", package="QSutils")
    lst <- ReadAmplSeqs(filepath,type="DNA")

    # Compute the alignment's IC profile.
    GetInfProfile(lst$hseqs)
    # Also taking into account haplotype frequencies.
    GetInfProfile(lst$hseqs,lst$nr)
