Crate mzdata[−][src]
Expand description
mzdata provides basic access to raw and processed mass spectrometry data formats in Rust.
The library currently supports reading:
- MGF files using
MGFReader
incrate::io::mgf
- mzML files using
MzMLReader
incrate::io::mzml
It also includes a set of representation layers for spectra in crate::spectrum
Example
use std::fs; use mzdata::io::prelude::*; use mzdata::io::mzml::MzMLReader; let mut ms1_count = 0; let mut msn_count = 0; let mut reader = MzMLReader::open_path("./test/data/small.mzML").unwrap(); for scan in reader { if scan.ms_level() == 1 { ms1_count += 1; } else { msn_count += 1; } } println!("MS1 Count: {}\nMSn Count: {}", ms1_count, msn_count); assert_eq!(ms1_count, 14); assert_eq!(msn_count, 34);
It also provides a sorted data structure for representing peak lists, PeakSet
and a trait implementing the majority of the logic, PeakCollection
.

Modules
The data structures and components that represent a mass spectrum and how we access their data.
Macros
Structs
Represent a single m/z coordinate with an intensity and an index. Nearly the most basic peak representation for peak-picked data.
Represent a single neutral mass coordinate with an intensity, a known charge and an index.
Enums
Represents a unit of mass accuracy, and provides the means for measuring them.
Traits
A trait for an ordered container of mass spectral peaks. The trait
interoperates with CoordinateLike
.
