PTXQC: A package for computing Quality Control (QC) metrics for Proteomics (PTX)
Description
The following sections describe the main components:
Input
Valid input data are either the files from MaxQuant's .txt folder (all versions from MaxQuant >= 1.0 upwards are supported)
or a single mzTab file. All mzTab files will work, but most metrics can be obtained from OpenMS' mzTab as produced
by the QualityControl TOPP tool (from OpenMS 2.5 onwards).
Important functions
The central function of this package is called createReport and it accepts either MaxQuant or mzTab data, along with
a configuration (optional).
There is a parser for mzTab MzTabReader and MaxQuant txt files MQDataReader, as well as a plethora of QC metrics
derived from a common qcMetric class and scoring functions qual..., e.g. qualGaussDev.
Configuration
The user can modify the behaviour of PTXQC, e.g. to enable/disable certain metrics or change scoring thresholds, via a YAML object/file.
By default a Yaml file is written automatically side-by-side to the input files upon running PTXQC for the first time on a particular input.
A custom Yaml object can be passed to the main createReport function for customization.
Use yaml::yaml.load_file(input = 'myYAML.yaml') to load an existing file and pass the Yaml object along.
Output
Either a PDF and/or Html report which contains QC plots and a description of the metrics.
