nmrml2isa-qt is available on PyPI, so if pip is installed on your machine, installing nmrml2isa should be quite straightforward, without the need to worry about dependencies. It is also possible to install nmrml2isa development version directly from the nmrml2isa-qt GitHub repository.


nmrml2isa-qt is a Python3 program only !


Windows users can either install nmrml2isa-qt as described below or use a ‘ready to go’ Windows executable (no python install required). The executables be found on the nmrml2isa-qt Github release section. See file nmrml2isa_gui.exe.



Without pip you’ll have to install the requirements yourself, otherwise running will fail when trying to import nmrml2isa for the first time.
