See below for 5 min video for how to use either mzml2isa-qt, imzml2isa-qt or nmrml2isa-qt.
nmrml2isa only requires that you put all you nmrML and zipped raw files in the same folder, and parsing should work fine. Note that reference to RAW files is extracted from the mzML files, so if you plan to create an ISA archive after mzml2isa creates ISA files, don’t forget to include those as well.
/ └ home/ └ metabolomics/ └ nmrML_study1/ # the name of the folder doesn't matter ├ Sample1.nmrML # the name of the file must correspond to the sample name ├ Sample2.zip # the raw files should be zipped and called exactly like the nmrML ├ Sample2.nmrML ├ Sample2.zip └ ... └ nmrML_study2/ ├ Sample1.nmrML ├ Sample2.zip ├ Sample2.nmrML ├ Sample2.zip └ ...
- Directory containing the mzML files. e.g. ‘nmrML_study1’ in the above example
- Output folder (automatically the same as input)
- Study name (automatically the same as the input folder name, e.g. ‘nmrML_study1’ in the above example)
- If the ‘input folder’ contains multiple studies then mzML2ISA will be run each study, e.g. in the above example if ‘metabolomics’ folder was chosen as the ‘input folder’ then the parsing will be performed on both studies (‘nmrML_study 1’, ‘nmrML_study 2’)
- If selected, separate assay files will be created for positive and negative assays
- If selected, the output folder will be the same as the input folder and input folder name will be used as the study name
- The ‘Add Metadata’ button will open a new dialog box where users can add more metadata
- Start the conversion process!
Adding additional metadata¶
Users can add additional metadata manually through the dialog box below. However, all this information can be added at the final stage with ISAcreator tool.
The following dialog boxes after the convert button is pressed. By default this is run in parallel (multiple cores). The following file types will be generated Investigation, Study and Assay
