To efficiently test many different levels design of experiment (DoE) is used. Box-Behnken and central composite designs set three evenly spaced levels for each parameter. The method 'getDefaultXcmsSetStartingParams' provides default values for the lower and upper levels defining a range. Since the levels are evenly spaced the middle level or center point is calculated automatically. To edit the starting levels of a parameter set the lower and upper level as desired. If a parameter should not be optimized, set a single default value for 'xcms' processing, do not set this parameter to NULL. + +The method 'getDefaultXcmsSetStartingParams' creates a list with default values for the optimization of the peak picking methods 'centWave' or 'matchedFilter'. To choose between these two method set the parameter accordingly. + +----- + +Github Repo IPO: https://github.com/glibiseller/IPO/blob/master/vignettes/IPO.Rmd + +Publication : http://www.biomedcentral.com/1471-2105/16/118 + +----- + +**Dependencies** + + Install all dependencies for IPO + + > source("http://bioconductor.org/biocLite.R") + + > biocLite("CAMERA") + + > biocLite("xcms") + + > install.packages("rsm") + + Install RTools + + For windows: + + Download and install RTools from http://cran.r-project.org/bin/windows/Rtools/ + + For Unix: + + Install the R-development-packages (r-devel or r-base-dev) + + Install packages needed for installation from github + + > install.packages("devtools") + + Install IPO + + > library("devtools") + + > install_github("glibiseller/IPO") + + </help> +</tool> \ No newline at end of file
