This crate allows to read Bruker TimsTOF data.
Basics
Two primary data types are exposed:
- Spectra: A traditional representation that expresses intensitites in function of mz values for a given precursor.
- Frames: All recorded data from a single TIMS elution (i.e. at one specific retention_time).
File formats
Two file formats are supported:
- Bruker .d folder containing:
- analysis.tdf
- analysis.tdf_bin
- miniTDF - ProteoScape optimized Bruker file-format. Similar to TDF, miniTDF consists of multiple files: a binary '.bin'
and an index '.parquet' file. The file-names are made up to the following convention:
<producing-engine-name>.<domain-name>.<extension>. e.g. for MS2 spectrum information:<producing-engine-name>.ms2spectrum.<extension>. Therefore the following files are expected in the provided ms2 folder:- *.ms2spectrum.bin
- *.ms2spectrum.parquet
