Peak height versus peak volume
Given a standard NOESY-based protein structure determination: Does anyone have any information on the benefits of measuring peak intensity by a volume integration method rather than simply measuring the peak height.
Obviously integration is theoretically more accurate, but does it make any difference to the quality of the structures produced? especially if peak lineshapes are comparable?
I was hoping to find some study comparing structures produced by both methods.....
I'm also curious about the benefits of distance-calbrating NOEs to a curve rather than simply putting restraints...

NMR structures of polytopic integral membrane proteins.
Mol Membr Biol. 2011 Aug 2;
Authors: Patching SG
Abstract Membrane proteins represent up to 30% of the proteins in all organisms, they are involved in many biological processes and are the molecular targets for around 50% of validated drugs. Despite this, membrane proteins represent less than 1% of all high-resolution protein structures due to various challenges associated with applying the main biophysical techniques used for...

[NMR paper] NMR structure of the integral membrane protein OmpX.
NMR structure of the integral membrane protein OmpX.

J Mol Biol. 2004 Mar 5;336(5):1211-21
Authors: Fernández C, Hilty C, Wider G, Güntert P, Wüthrich K
The structure of the integral membrane protein OmpX from Escherichia coli reconstituted in 60 kDa DHPC micelles (OmpX/DHPC) was calculated from 526 NOE upper limit distance constraints. The structure determination was based on complete sequence-specific assignments for the amide protons and the Val, Leu, and Ile(delta1)...

[Question from NMRWiki Q&A forum] Exporting integral data for use in calculations
Exporting integral data for use in calculations
Hello people,
For my internship I am attempting to fully automate monomer composition analysis on Bruker TOPSPIN 2.0 using visual basic and macro's. It's almost fully functional but I've come across the following problem:
I want to use the integral data of a spectrum in calculations (i.e. export them to an excel template) but so far I've found no way of exporting integral data without using the mouse (I can make visual basic simulate mouse clicks, but it's not a method I like using since it makes the program very prone to failure or...
