POISE is a Python package for the numerical optimisation of NMR parameters. It works by iteratively acquiring NMR spectra with different parameters and using a cost function to determine the optimal point.
The software comprises two parts:
the user-facing frontend, which runs in Bruker's TopSpin software. It can be executed from the TopSpin command line, or called from an AU or Python script (the documentation contains more instructions on this).
the backend, which is hidden from the user; it runs on a system installation of Python 3.6+.
To install POISE, you will need:
TopSpin. The minimum tested version is 3.6 but we expect that this should work with versions going back to 3.2. If there are bugs, please do inform us.
Note that other instrument manufacturers are not currently supported.
Python 3.6 or later. This refers to a system installation, which is entirely separate from that in TopSpin. Please download and install that (many instructions are available online).
POISE can then be installed using
pip (which uses the system installation of Python):
python -m pip install nmrpoise # or 'python3'
If any errors occur, please see the documentation, or contact us.
To upgrade or reinstall POISE use:
python -m pip install --upgrade nmrpoise --no-cache-dir
Note that the
--no-cache-dir flag is necessary (its purpose is explained in the documentation).
The documentation is hosted at https://foroozandehgroup.github.io/nmrpoise; it contains complete instructions on how to set POISE up and use it.
There is also a video guide available at https://www.youtube.com/watch?v=QTCeSCRZs4I.
