Hello all,

I am trying to understand/decode the an NOE file that is supposed to show
NOE distance restraints. I am not sure whether the format it is written in
is Xplor, but I am confused as to what information it provides.

Here is a line sample:

assign ((resid 1 and name HA)) ((resid 1 and name HG1)
                                           (resid 1 and name HG2))
3.567 3.567 0.892 !

I do not understand why it gives me three numbers. This file is supposed
to show NOE derived distance restraints, and I am thinking this file
specifies inter-proton distances, but I do not understand its format.

Any help would be greatly appreciated,
