Profex Tips and Tricks: Fixing the Reference Structure Database
When upgrading from Profex 4.1 or older to version 4.2 or newer, adding and indexing new structure files may no longer work. But the solution is simple... ... https://www.youtube.com/watch?v=UqBtPYgMk8E
Profex version 4.3 comes with a new feature: The COD database can be searched directly, and CIF files can be imported and converted to the STR format very easily.
This video shows how to install the COD database and how to set up Profex accordingly.
