A new approach for automated peak picking of multidimensional protein NMR spectra with strong overlap is introduced, which makes use of the program AUTOPSY (automated peak picking for NMR spectroscopy). The main elements of this program are a novel function for local noise level calculation, the use of symmetry considerations, and the use of lineshapes extracted from well-separated peaks for resolving groups of strongly overlapping peaks. The algorithm generates peak lists with precise chemical shift and integral intensities, and a reliability measure for the recognition of each peak. The results of automated peak picking of NOESY spectra with AUTOPSY were tested in combination with the combined automated NOESY cross peak assignment and structure calculation routine NOAH implemented in the program DYANA. The quality of the resulting structures was found to be comparable with those from corresponding data obtained with manual peak picking.
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...

[Question from NMRWiki Q&A forum] Auto peak picking of N15Edit NOESY and C13 Edit NOESY spectrum
Auto peak picking of N15Edit NOESY and C13 Edit NOESY spectrum
Dear friends,
I am in process of doing structure calculation of a dimeric protein. The problem I faced is regarding the assignment of N15Edit NOESY and C13 Edit NOESY spectrum.I have already processed the fid data and converted to sparky ucsf format. Is there options available in sparky for auto peak picking, integration and assignment of my NOESY spectrum? And second query is regarding the generation of input files for structure calculation. In our Lab we are using ARIA 2.1 software for structure calculation? Is there any...

[NMR analysis blog] Intelligent Peak Picking of 1D NMR Spectra
Intelligent Peak Picking of 1D NMR Spectra
In case you hadn´t noticed, version 7 of Mnova was released just a few days ago.
Whilst this new version presents a number of significant improvements in the software, in this post I would like to focus on a new peak picking concept which, to the best of my knowledge, is novel and in some way, revolutionary. I will try to keep this as short and clear as possible, just to illustrate the very basic ideas that motivated this new approach to peak picking. In the next posts I will elaborate further on some of the new points introduced here.
