TraceGroomer

TraceGroomer is a solution for formatting and normalising isotope-labeled (a.k.a Tracer) Metabolomics given file(s), to produce the tabular files which are ready for DIMet tool.

Not only one, but several input formats are accepted by TraceGroomer!: these input formats are described in detail (visit the Wiki link provided in our documentation section), e.g. IsoCor output files are currently supported.

TraceGroomer processes your data in seconds!

For any type of the supported inputs, TraceGroomer generates an independent file for each type of quantification: i) total metabolite abundances ii) Isotopologues iii) Isotopologues' proportions and iv) mean enrichment (a.k.a fractional contributions).

Advantages of using TraceGroomer for preparing your data for DIMet:

• if only Isotopologues' absolute values are provided, TraceGroomer generates all the other quantifications automatically.
• fast, automatic formatting is performed, as well as the normalization chosen by the user: whether by the amount of material and/or by an internal standard.
• useful advanced options are offered (e.g. different modalities of normalization by the amount of material).

Note : TraceGroomer does not correct for naturally occurring isotopologues. Your data must be already processed by another software that performs such correction (e.g. IsoCor).

Requirements

TraceGroomer requires Python 3.10+. Running in a virtual environment is highly recommended.

Install it via pip: pip install tracegroomer

Tracegroomer is also available as a conda package

Alternatively, if you are a developer, you can do a local install:

poetry install

python -m tracegroomer --help

Documentation

All the details about how to use TraceGroomer can be found on the dedicated Wiki page. This is where you will find the information of the supported formats, examples, and how to run TraceGroomer.
