[Xplor-nih] VMD-XPLOR

[Marcela Madrid]

hi,

I started using VMD-XPLOR to visualize a molecule and its NMR 
constrains. I would like to understand better what I am getting. I have 
converted the AMBER restrain file to XPLOR format, and now I have a set 
of three distances: d dlow dhigh. I understand the exact meaning of 
these numbers depends on the restraining function used. So my question 
is, what is the default for VMD-XPLOR? For example if I set
2.8, 0.5, 0.5
does that mean the NOE distance is 2.8+-0.5 A?
Or should I specify this as 2.8, 2.3, 3.3 ?

Another question is what is the "cutoff" button that is in the NOE 
window of VMD-XPLOR?

Thanks so much, Marcela
