PerformParamsOptimization: Perform Parameters Optimization

In xia-lab/MetaboAnalystR: An R Package for Comprehensive Analysis of Metabolomics Data

Perform Parameters Optimization

Description

This function is used to optimize the critical parameters of peak picking and alignment for the following data processing. It utilizes the trimed data and the internal instrument-specific parameters. Parallel computing will be performed. The number of cores user want to use could be specified.

Usage

PerformParamsOptimization(
  mSet,
  param = NULL,
  method = "DoE",
  ncore = 4,
  running.controller = NULL
)

Arguments

mSet	mSet object, usually generated by 'PerformROIExtraction' or 'PerformDataTrimming' here.
param	List, Parameters defined by 'SetPeakParam' function.
method	Character, method of parameters optimization, including "DoE' only. Default is "DoE". Other method is under development.
ncore	Numeric, CPU threads number used to perform the parallel based optimization. If thers is memory issue, please reduce the 'ncore' used here. For default, 2/3 CPU threads of total will be used.
running.controller	The resuming pipeline running controller. Optional. Don't need to define by hand.

Details

PerformParamsOptimization

Value

will a parameter object can be used for following processing
