GetInfProfile: Information content profile of an alignment

In VHIRHepatiques/QSutils: Quasispecies Diversity

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)
