Turn a spectrum file into a token, or a token into a file. Files are read in this page and never uploaded.
File to token
No file open.
No file handy? Download an example: example.mzML, example.mgf or example.ms2.
Or paste a peak list
Two columns, m/z and intensity. CSV, TSV or whitespace, with an optional header.
Token to file
No token loaded.
mzML holds everything a token holds, so a token written to mzML and read back is the same spectrum. MGF and MS2 carry only a precursor and peaks. Anything they cannot hold is listed when you save.
