selex.mmProb {SELEX} | R Documentation

## Compute prior probability of sequence using Markov model

### Description

A function used to calculate and return the prior observation probability of a DNA sequence `seqStr` as predicted by Markov model `markovModel`.

### Usage

    selex.mmProb(seqStr, markovModel)

### Arguments

`seqStr` | A character string representing the DNA sequence to be evaluated.
`markovModel` | A Markov model handle.

### Value

`selex.mm` returns the prior observation probability of `seqStr`.
