Quickstart

Rust:

use opentimstdf::Reader;

let reader = Reader::open("my_bundle.d")?;
let calib = reader.calibration()?;
let frame = reader.frame(1)?;
for peak in reader.decode_peaks(&frame)? {
    let mz = calib.tof_to_mz(peak.tof);
    let im = calib.scan_to_inv_mobility(peak.scan);
    println!("scan={} mz={:.4} 1/K0={:.4} i={}", peak.scan, mz, im, peak.intensity);
}

Python:

import opentimstdf

reader = opentimstdf.Reader("my_bundle.d")
calib = reader.calibration()
frame = reader.frame(1)
for peak in reader.decode_peaks(frame):
    mz = calib.tof_to_mz(peak.tof)
    print(peak.scan, mz, peak.intensity)
