PeCorA_preprocessing: PeCorA_preprocessing

In jessegmeyerlab/PeCorA: Peptide correlation analysis

PeCorA_preprocessing

Description

steps to pre-process data for PeCorA

Usage

PeCorA_preprocessing(t, area_column_name, threshold_to_filter, control_name)

Arguments

t	data in PeCorA format
area_column_name	column number with peak areas
threshold_to_filter	threshould value of peak areas to filter
control_name	control reference

Details

Peak areas are log transformed and scaled to center.After global scaling, each peptide scaling was performed to center each peptide relative to the mean of the control group’s peak area.

Value

dataframe output of pre-process data ready for PeCorA analalysis
