LC-MS Spectra Upload

MetaboAnalyst currently supports mzML, mzXML, CDF or mzData formats in centroid mode. Quality control (QC) spectra are not required but recommended. QC should start with "QC_" or marked as "QC" in meta data. BLANK should be marked as "BLANK" in meta data for subtraction. The following two data types are allowed:

  1. [Required] Spectra uploaded as individual zip files - one zip (.zip) per spectrum [max: 200 spectra].
  2. [Optional] Meta data uploaded as a plain text (.txt) file containing two columns - spectral names and group labels [example]

Spectra processing can take a long time to complete, to avoid waiting:

  1. For guest users (default), after job submission, click Create Bookmark URL and save the URL so you can return later to check your job status.
  2. For registered users, use the buttons on the left panel to manage your projects.

Please Select all files, then click Upload to start. Once the upload has completed, click Proceed to continue.
