dear seeker of knowledge, my former university has decided to remove access to the server running my software and downloads … We are working on setting up new servers. I am sorry for the inconvenience. Several tools can be accessed from the links below. If you use our software programs or databases, then please cite our work. It is fair and polite, and it helps me maintain a lab to provide even more tools.

Best wishes, Frans Mulder

You can find POTENCI python source code for random coil chemical shift prediction at github:

You can download the CheZOD database used for testing disorder predictors at this link:

The ncSPC program for assessing structural propensities is found here (for the moment):
