artMS configuration template

Source: R/data.R

The configuration file in yaml format contains the configuration details required to run artmsQuantification(), which includes quality control functions

artms_config

Format

The configuration (yaml) file contains the following sections:

files

  • evidence : /path/to/the/evidence.txt

  • keys : /path/to/the/keys.txt

  • contrasts : /path/to/the/contrast.txt

  • summary : /path/to/the/summary.txt

  • output : /path/to/the/output/results/results.txt

qc

  • basic: 1 # 1 = yes; 0 = no

  • extended: 1 # 1 = yes; 0 = no

  • extendedSummary: 0 # 1 = yes; 0 = no

data

  • enabled : 1 # 1 = yes; 0 = no

  • silac:

    • enabled : 0 # 1 for SILAC experiments

  • filters:

    • enabled : 1

  • contaminants : 1

  • protein_groups : remove #remove, keep

  • modifications : ab # PH, UB, AB, APMS

  • sample_plots : 1 # correlation plots

msstats

  • enabled : 1

  • msstats_input : # blank if not previous msstats input file is available

  • profilePlots : none # before, after, before-after, none

  • normalization_method : equalizeMedians # globalStandards (include a reference protein(s) ), equalizeMedians, quantile, 0

  • normalization_reference : #should be a value in the Protein column

  • summaryMethod : TMP # "TMP"(default) means Tukey's median polish, which is robust estimation method. "linear" uses linear mixed model. "logOfSum" conducts log2 (sum of intensities) per run.

  • censoredInt : NA # Missing values are censored or at random. 'NA' (default) assumes that all 'NA's in 'Intensity' column are censored. '0' uses zero intensities as censored intensity. In this case, NA intensities are missing at random. The output from Skyline should use '0'. Null assumes that all NA intensites are randomly missing.

  • MBimpute : 1 # only for summaryMethod="TMP" and censoredInt='NA' or '0'. TRUE (default) imputes 'NA' or '0' (depending on censoredInt option) by Accelated failure model. FALSE uses the values assigned by cutoffCensored

  • For all othe features, please check documentation for MSstats' dataProcess function

output_extras
