Compressed sensing and the reconstruction of ultrafast 2D NMR data: Principles and biomolecular applications.
J Magn Reson. 2011 Apr;209(2):352-8
Authors: Shrot Y, Frydman L
A topic of active investigation in 2D NMR relates to the minimum number of scans required for acquiring this kind of spectra, particularly when these are dictated by sampling rather than by sensitivity considerations. Reductions in this minimum number of scans have...

CONNJUR - open source integration environment for biomolecular NMR data analysis
CONNJUR Project website
The CONNJUR Project is developing an open source integration environment for biomolecular NMR data analysis. CONNJUR software is a workflow generator, based on legacy NMR analysis applications, that is being developed as Open Source Software -- it is perpetually free for anyone to use, modify and distribute.
CONNJUR is developed by a community of NMR spectroscopists and scientific programmers who aim to create and maintain NMR analysis tools bounded by the goals of excellent end-product, free of charge, open source software using the...

[CSEARCH NMR-Database blog] Quality Analysis of Journals with respect to their C13-NMR Data
Quality Analysis of Journals with respect to their C13-NMR Data
I have analyzed the combined CSEARCH and SPECINFO - collections, which are commercially available via http://chemgate.emolecules.com and as NMRPREDICT via http://www.modgraph.co.uk/ , with respect to the quality of the underlying data and their origin in a large variety of journals.
The result of this investigation has been reviewed in 'Trends in Analytical Chemistry' and is available here:
http://dx.doi.org/10.1016/j.trac.2009.03.012
I hope that this paper promotes the integration of spectral similarity searches and...

[NMR analysis blog] Binning and NMR Data Analysis
Binning and NMR Data Analysis
Yesterday I mentioned that many NMR arrayed experiments suffer from unwanted chemical shift variations due to fluctuations in experimental conditions such as sample temperature, pH, ionic strength, etc. This phenomenon is very common in NMR spectra of e.g. biofluids (metabonomics/metabolomics) but also exists in many other experiments such us Relaxation, Kinetics and PFG NMR spectra (diffusion).
This problem negatively affects the reliability of quantitation using, for instance, peak heights, and for this reason integration is, in general, a more robust...

[NMR analysis blog] Basics on Arrayed-NMR Data Analysis (Part IV)
Basics on Arrayed-NMR Data Analysis (Part IV)
Next up in my survey on analysis of arrayed NMR experiments ( View Parts 1, 2, 3 ) takes me to a quick overview of the different methods of data evaluation, such as the determination of peak heights and peak areas from arrayed experiments. Here you go...
Of the different existing methods for the extraction of peak intensities from arrayed NMR spectra (see ), Mnova provides the following ones:
(1) Peak area integration
This is the default method in Mnova Data Analysis module (see figure below)

[NMR analysis blog] Basics on Arrayed-NMR Data Analysis (part I)
Basics on Arrayed-NMR Data Analysis (part I)
In this post I will cover some basic concepts on the analysis of a very important class of NMR experiments, the so-called Arrayed NMR spectra. The concept is very simple: an arrayed experiment is basically a set of individual spectra acquired sequentially and related to each other through the variation of one or more parameters and finally grouped together to constitute a composite experiment. These experiments are also known as ‘pseudo-2D’. For example, in the case of Bruker spectra they have the same file name as 2D spectra, that is ser files...

Mnova 6.0, at last! GSD, Line Fitting, Data Analysis, handling of LC/GC/MS data and much more!
It's been over 6 weeks since my last post on this blog but don’t worry, I haven’t been idle. On the contrary, I have a very good excuse for this lack of posts: We all at Mestrelab have been working very hard trying to get version 6.0 of Mnova finished. Now I’m delighted to announce that we have done it and version 6.0 is finally available for download from our Web site. This is certainly a major upgrade of the software in which we have put a lot of work and passion. It brings a number of...
