iMet, the metabolite identification tool using tandem MS/MS spectrometry. Usage is as follows:
  • Choose positive or negative ionization.
  • Enter the parental ion peak mass (in Da).
  • Click on any of the blue buttons to submit a spectrum. Note that you can submit more than one spectrum, as long as it belongs to the same sample. IMPORTANT! The format is strict, and each spectrum MUST be a text file containing at least two columns, the first one should contain the m/z of each peak, and the second the relative intensity corresponding to that m/z. Separation between columns can be a white space or a comma (csv-like file). All lines starting with the "#" character will be ignored by the algorithm.
  • Click Send to submit your job.
  • Click Clear to start over from scratch.
Once you submit your query, a panel will appear stating whether your job was sent correctly or whether there was some error. If there were no errors, the panel will also display a link to the results page, and a brief summary of the input options sent.

This page is in alpha version. Do not hesitate to contact us if you find any problems or bugs.
