I need to analyze spectrometry data on GNPS. I have data in pdf and text files. the input extensions for GNPS are mzML or mzXML. Please suggest an online tool for this purpose. Thanks in advance.
Can you explain why you have data in PDF and text files? Have the raw data already been processed using another software?
To use GNPS, you will need either the raw data from the mass spectrometer which you can then convert following these instructions (https://ccms-ucsd.github.io/GNPSDocumentation/fileconversion/) or you can submit processed data (such as a mgf file).
Tell us more about what you have done - are your data LC-MS/MS data from a QTOF or an orbitrap etc. Sometimes the most straight forward thing to do is upload the raw data (after conversion).
