If you need help with the ChemConverter, it's right here!


I cannot create a profile on the admin GUI (Webserver does nothing or ERROR Message)

  • Answer: There can be multiple reasons, but the most common are:

    • You are trying to upload a binary file (not supported yet!)
    • There's no reader (yet) for your specific data type and the standard reader don't work either.
    • You are in the wrong menu, please press the right button.
      Please do not click import, create instead

I created a profile for my data file on the admin GUI but after uploading it to the ELN it will not be converted.

  • Answer: If you are sure, that the reason is not the converter itself (because you tested it on a standalone version and it works), we need to add your file extension/type to our whitelist. Please let us know.

Even after choosing a suitable data type (and a correct conversion) the ELN says "Preview not available" and/or "Spectra Editor: Reprocess"

Preview not available

  • Answer: The two common mistakes occur if there

    • was a freeze, loose of connection or other bug during the upload or the conversion process. You can try to click on the orange button to regenerate the spectra.
    • isn't a working layout for this technique yet. You can wait for the next update and try again later or help us with your expertise to create a suitable layout.
  • Workaround: Just to have basic features for looking at the curves, an already more accomplished layout like CV, UV/VIS or NMR is recommended to be used.

Frequently Asked Questions (FAQ)

Why using .jdx and not e.g. .csv for the converter output?

What data formats are supported as input

  • Short answer: Mostly all common non-binary files (txt, csv, dta ...) are at least with basic feature.

  • Long answer: We encourage you to look at the reader documentation page. Here you will also find a list of readers with advanced features.

  • Answer: Of course there are and we are happy to help you against closed, unreadable and proprietary data! Therefore, a document with simple and basic guidelines (currently in beta status) was created.
