Does Metaboanalyst admit negative numbers?

Hi everyone,
I would like to know if Metaboanalyst admits negative numbers because when I upload the file txt attached in this message, Metaboanalyst makes t-test, volcano but the FC is not right.

Thanks in advance,

MetaboAnalyst performs analysis (including FC) when the uploaded data are in its supported formats (see our many examples and tutorials).

  • What is the data type?
  • Why it contains so many negative numbers?
  • Does it belong to any data types supported by the tool?

If the uploaded data are outside the intended scope of application, it is up to users to take the risk and interpret the results.
