Hello,
You can stereospecifically assign a peak (dimension) by clicking on the peak in the peak table and clicking on the Assign button (or clicking on a peak in a spectrum display window and hit the 'a' key). Then (in the Assignment: Assignment Panel dialog) click on the relevant Hba (or whatever) in the relevant dimension table at the left, then click the Re-assign **** button (**** specific to what you are doing). In that (the Molecule: Atom Browser dialog) you can click on Hb2 (or whatever), although you need to make sure that "stereospecific" is checked in the Options tab in order for this option to be shown. That should do it.

The designated html file is not there at the appropriate location. The missing html help file is supposed to be at the location "/home/nmrware/ccpnmr/ccpnmr2.4/python/ccpnmr/format/doc/ProchiralStatus.html"
