units: hd



 Hi,
 Last week I asked a question about constraining torsions when docking a
 flixible ligand to protein using AutoDock 3.0. I haven't got any replies
 yet. (Unfortunately).
 Now I have another question about a unit symbol hd. I don't know what unit
 it is. I came across with it when I was trying to define an energy barrier
 in AutoDock using command 'barrier 10 000'  and the output file told me
 that the energybarrier was set to 10000hd. What is this energy unit hd? I
 was looking for an explanation in the internet and I found out that it
 means hogshead, which is a volume unit. I don't think that's the case
 here.
 In addition to this issue, any kind of information about constraining
 torsion using AutoDock would probably  help me in my research project (for
 pro graduation work).
 Thank you.
