There are some bugs in the old NMR tool for some Origin versions. And it is too old and not easy to maintain.
We made this app to integrate the old tool’s toolbar and items in Origin menu in a new HTML dialog. It includes all features of the old tool. And we will use this app to maintain the tool. If you find bugs or have suggestions, you can send to us by submitting a ticket.

Download the file NMR_Tools.opx, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.
NOTE: This tool requires OriginPro.
