OpenSwathWorkflow

Complete workflow to run OpenSWATH

This implements the OpenSWATH workflow as described in Rost and Rosenberger et al. (Nature Biotechnology, 2014) and provides a complete, integrated analysis tool without the need to run multiple tools consecutively. See also http://openswath.org/ for additional documentation.

It executes the following steps in order, which is implemented in OpenSwathWorkflow:

  • Reading of input files, which can be provided as one single mzML or multiple "split" mzMLs (one per SWATH)
  • Computing the retention time transformation using RT-normalization peptides
  • Reading of the transition list
  • Extracting the specified transitions
  • Scoring the peak groups in the extracted ion chromatograms (XIC)
  • Reporting the peak groups and the chromatograms

See below or have a look at the INI file (via "OpenSwathWorkflow -write_ini myini.ini") for available parameters and more functionality.

Input: SWATH maps and assay library (transition list)

SWATH maps can be provided as mzML files, either as single file directly from the machine (this assumes that the SWATH method has 1 MS1 and then n MS2 spectra which are ordered the same way for each cycle). E.g. a valid method would be MS1, MS2 [400-425], MS2 [425-450], MS1, MS2 [400-425], MS2 [425-450] while an invalid method would be MS1, MS2 [400-425], MS2 [425-450], MS1, MS2 [425-450], MS2 [400-425] where MS2 [xx-yy] indicates an MS2 scan with an isolation window starting at xx and ending at yy. OpenSwathWorkflow will try to read the SWATH windows from the data, if this is not possible please provide a tab-separated list with the correct windows using the -swath_windows_file parameter (this is recommended). Note that the software expects extraction windows (e.g. which peptides to extract from which window) which cannot have overlaps, otherwise peptides will be extracted from two different windows.

Alternatively, a set of split files (n+1 mzML files) can be provided, each containing one SWATH map (or MS1 map).

Since the file size can become rather large, it is recommended to not load the whole file into memory but rather cache it somewhere on the disk using a fast-access data format. This can be specified using the -readOptions cache parameter (this is recommended!).

The assay library (transition list) is provided through the -tr parameter and can be in one of the following formats:

Parameters

The current parameters are optimized for 2 hour gradients on SCIEX 5600 / 6600 TripleTOF instruments with a peak width of around 30 seconds using iRT peptides. If your chromatography differs, please consider adjusting -Scoring:TransitionGroupPicker:min_peak_width to allow for smaller or larger peaks and adjust the -rt_extraction_window to use a different extraction window for the retention time. In m/z domain, consider adjusting -mz_extraction_window to your instrument resolution, which can be in Th or ppm.

Furthermore, if you wish to use MS1 information, use the -use_ms1_traces flag and provide an MS1 map in addition to the SWATH data.

If you encounter issues with peak picking, try to disable peak filtering by setting -Scoring:TransitionGroupPicker:compute_peak_quality false which will disable the filtering of peaks by chromatographic quality. Furthermore, you can adjust the smoothing parameters for the peak picking, by adjusting -Scoring:TransitionGroupPicker:PeakPickerMRM:sgolay_frame_length or using a Gaussian smoothing based on your estimated peak width. Adjusting the signal to noise threshold will make the peaks wider or smaller.

Output: Feature list and chromatograms

The output of the OpenSwathWorkflow is a feature list, either as FeatureXML or as tsv (use -out_features or -out_tsv) while the latter is more memory friendly and can be directly used as input to other tools such as mProphet or pyProphet. If you analyze large datasets, it is recommended to only use -out_tsv and not -out_features. For downstream analysis (e.g. using mProphet or pyProphet) also the -out_tsv format is recommended.

The feature list generated by -out_tsv is a tab-separated file. It can be used directly as input to the mProphet or pyProphet (a Python re-implementation of mProphet) software tool, see Reiter et al (2011, Nature Methods).

In addition, the extracted chromatograms can be written out using the -out_chrom parameter.
