Detailed Description

Simulates peptide detectability.

The peptide detectability is predicted based on a support-vector machine. Alternatively the detectability can be set to a default value for all peptides if no model is given.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
dt_simulation_on	string	false	true, false	Modelling detectibility enabled? This can serve as a filter to remove peptides which ionize badly, thus reducing peptide count
min_detect	float	0.5		Minimum peptide detectability accepted. Peptides with a lower score will be removed
dt_model_file	string	examples/simulation/DTPredict.model		SVM model for peptide detectability prediction

Note:

• If a section name is documented, the documentation is displayed as tooltip.
• Advanced parameter names are italic.

(

const DetectabilitySimulation &

source

)

Assignment operator.

predictDetectabilities()

void predictDetectabilities	(	std::vector< String > &	peptides_vector,
