different total number of Spectra in msconvert, compomics/ThermoRawFileParser and thermofisherlsms/RawFileReader

[asepsiswu]

MsBackendRawFileReader generated spectra lose the end spectrum(scanindex=7244) in msconvert and ThermoRawFileParser version. And in thermo Xcalibur, the total scan is 7244.
I tried two files and got the same results MsBackendRawFileReader lost the final scanindex

@asepsiswu thanks!!!

using https://bioconductor.org/packages/rawrr/
version >1.10

I fixed the assembly. executing

R> rawrr::installRawrrExe("https://github.com/fgcz/rawrr/releases/download/1.9.2/rawrr.1.9.2.exe")
versuche URL 'https://github.com/fgcz/rawrr/releases/download/1.9.2/rawrr.1.9.2.exe'

should solve the issue.

R> rawrr::sampleFilePath() |> rawrr::readIndex() |> nrow()
[1] 574
R> rawrr::sampleFilePath() |> rawrr::readSpectrum(scan = 1:600) |> length()
