M1a

Usage

M1a(submodel: Double -> CTMC<Codons<a>>, omega0: Double, p0: Double) → DiscreteDist<CTMC<Codons<a>>>

Arguments

A default beginning with ~ specifies a prior distribution.

submodel:

The model as a function of dN/dS

Default: |w:GY94(omega=w)|

omega0:

The dN/dS value for conserved sites

Default: ~Uniform(0,1)

p0:

The fraction of conserved sites

Default: ~Uniform(0,1)

Description

A mixture of conserved and neutral sites. The conserved sites have frequency p0 and dN/dS=omega0.

The M1a model modifies the M1 model to avoid forcing the conserved dN/dS to 0.

Examples

|w:GY94(omega=w,pi=F1x4)| +> M1a
|w:MG94(omega=w)| +> M1a
|w:FMutSel0(omega=w)| +> M1a
