Prototype for reading mzPeak files in .NET.

Usage

Reading

using MZPeak.Reader;

// Open an mzPeak file
var reader = new MzPeakReader("path/to/file.mzpeak");

// Access file-level metadata
Console.WriteLine($"{reader.SpectrumCount} spectra, {reader.ChromatogramCount} chromatograms");
Console.WriteLine($"Storage format: {reader.SpectrumDataFormat}");

// Iterate over spectra asynchronously
await foreach (var (description, data) in reader.EnumerateSpectraAsync())
{
    Console.WriteLine($"Spectrum {description.Index}: {description.Id}");
    Console.WriteLine($"  Time: {description.Time}");
    Console.WriteLine($"  Points: {data.Length}");
    Console.WriteLine($"  Profile: {description.IsProfile}, Centroid: {description.IsCentroid}");

    // Access scan information
    foreach (var scan in description.Scans)
    {
        Console.WriteLine($"  Scan config: {scan.InstrumentConfigurationRef}");
    }

    // Access precursor information (for MS2+ spectra)
    foreach (var precursor in description.Precursors)
    {
        Console.WriteLine($"  Precursor index: {precursor.PrecursorIndex}");
    }
}

// Iterate over chromatograms asynchronously
await foreach (var (description, data) in reader.EnumerateChromatogramsAsync())
{
    Console.WriteLine($"Chromatogram {description.Index}: {description.Id}");
    Console.WriteLine($"  Points: {data.Length}");
}
