HHmmm, this is different from the Amber 8 manual to which I was refering:
NMROPT = 0 no nmr-type analysis will be done;
> 0 NMR restraints/weight changes will be read
= 2 NOESY volume restraints or chemical shift restraints will
be read as well.
So perhaps the behaviour has changed between amber 7 and 8 (or just that the
manual has been updated correctly). Perhaps someone more familiar with this
area of the code could comment further...
All the best

Hi Ross
yes there were no NOESY volumes nor shift restraints. .. Just rdc and the
usual NOE/J based restraints. What surprised me was that rcd restraints were
supposed to require nmropt=2 (7 manual)... so at that point one worries what
is going on.

If you had no NOESY volume chemical shift restraints defined then nmropt = 2
would just have been treated as nmropt > 0 which in the absence of the above
restraints being defined is the same as nmropt=1. Hence the same results.
I hope this makes sense.

Subject: AMBER: Amber7 nmropt
This is regarding the nmropt statement in Amber 7
We updated an older rdc restraints file from Amber 6 to 7 and 8.
By accident, I left nmropt=1 for an Amber 7 run, subsequently I rerun this
with nmropt=2 (as per manual)
The data from both runs are identical and both contain alignment restraints.
Does anyone have any insights on this?
