Samples can be in either rows or columns. Both sample or feature names must be unique and consist of a combination of common English letters, underscores and numbers for naming purpose. Latin/Greek letters are not supported. The class labels must immediately follow sample names. Please visit our Data Formats page for more details.
Please upload the original XLSX datasheets from Metabolon directly without any editing or conversion. Note that there are three sheets (Chemical Annotation, Sample Meta Data and Peak Area Data) required to proceed.
