ARIA2 (Ambiguous Restraints for Iterative Assignment)


I just came across a publication DOI describing ARIA2 (Ambiguous Restraints for Iterative Assignment) is a software for automated NOE assignment and NMR structure calculation.

ARIA comes as a software library written in the object-oriented programming language Python. The modular design makes it easy for the user to extend and modify the program. The GUI is based on the graphics libraries Tcl/Tk and Tix, interfaced by Python.

ARIA runs on Linux, SGI machines and Mac OS X.

More details can be found on the website

I've added ARIA2 to the spectroscopy page.

The latest issue of Journal of Cheminformatics has a paper that might be of interest to a variety of people involved in spectroscopy or data visualsation. SpeckTackle: JavaScript charts for spectroscopy.

We present SpeckTackle, a custom-tailored JavaScript charting library for spectroscopy in life sciences. SpeckTackle is cross-browser compatible and easy to integrate into existing resources, as we demonstrate for the MetaboLights database. Its default chart types cover common visualisation tasks following the de facto ‘look and feel’ standards for spectra visualisation.

SpeckTackle is an open-source JavaScript library to create custom-tailored charts for spectroscopy in life sciences. Implemented charts exist for mass spectrometry, one- and two-dimensional NMR, UV/VIS, IR, and general continuous data use cases such as chromatograms.

The authors kindly supply a demo web page demonstrating different chart types and functions of the SpeckTackle library. Example data is embedded in the web page (800 kb file size). Click on the buttons at the top of the page to see the data displayed. For the Chromatogram, Difference Chart and Spectral Match click the button then the Add Data button.

Highlighting a section of the spectra expands the view and mouseover on the 2D NMR spectra provides a tooltip giving chemical shifts

I've added this to the spectroscopy resources page

ChemDoodle Web Components JCAMP Interpreter


Displaying spectra on the web is usually a pretty minimal experience, often simply an image file. Whilst there a number of desktop applications for viewing spectra, web-based tools were often limited to Java plugins which have now almost completely fallen out of favour.

The JCAMP data format (1) for spectra is pretty widely used and we are starting to see javascript implementations of viewers. This very nice example uses the ChemDoodle web components to display the spectra and provide interaction. Hovering close to a nucleus that has a peak correlation defined will highlight that nucleus and any other nuclei in its group along with highlighting the corresponding peak. Conversely hovering close to a peak that has correlated nuclei associated with it will highlight the set.

Chenomx NMR Suite


The latest update to the Chenomx NMR Suite has just been released, this includes a new batch processing wizard and several improvements. I checked with the developers and this update was built on a machine under Mac OS X 10.10 although the website had not yet been updated to include Yosemite compatibility.

There is a listing of spectroscopy applications here, and a comprehensive summary of compatibility of Scientific Applications under Yosemite here.




I just added Topspin from Bruker to the list of spectroscopy applications.

Topspin is capable of data processing of 1D and higher dimensional NMR datasets including Fourier transform, window functions, baseline and phase correction, peak picking, integration, line shape analysis (Gauss/Lorentz, dynamic NMR, solids), relaxation and multiplet analysis, spectrum and Fid simulation, printing/plotting, quantification, AU/Python/Macro programming. Optionally NUS processing and small molecule structure elucidation (demo licenses available). For Mac systems the CPU must be capable of executing 64bit-instructions according to “Intel Core 2 Duo” processor type or newer.


Mnova 9.1.0 released


Mestrelab Research have just announced the release of the NMR application Mnova 9.1.0. This release fixes several bugs and incorporates many new features on NMR, MS, the Molecule Editor and the GUI.

This new version also includes the release of the Mnova Screen plugin, an automatic tool for the analysis of ligand screening NMR data.

It also includes a long list of bug fixes


iNMR has been updated


The very popular NMR processing tool iNMR has been updated

The new versions 5.3.7 (for Mac) and 2.3.7 (for Windows), both available since June 20, add Covariance NMR to the processing toolbox. This technique creates a symmetric square matrix, starting from any 2-D matrix. The result can look completely different from the starting spectrum, though the information contained is necessarily the same. An example is hsqc-tocy (a kind of hetero-correlation experiment). After normal processing, it has two different axes: a 1-H axis and a 13-C axes. Starting from here you can apply two different kinds of Covariance. The so-called Direct Covariance creates a symmetric H-H matrix. The so-called Indirect Covariance creates a symmetric C-C matrix. Both are homo-correlation plots.

A more detailed description is available here:

This link leads to the pioneer of the method:

There are more spectroscopy applications for Mac OSX here


LSD and CASA added to spectroscopy page


I’ve just added to two applications to the spectroscopy page.

LSD (Logic for Structure Determination) is designed to find all possible molecular structures of an organic compound that are compatible with the experimental spectroscopic data.

Structure building relies on connectivity data found in 2D NMR spectra, without any reference to a chemical shift database. Molecular structures containing up to 50 non-hydrogen atoms were investigated by means of the LSD program. The measurement protocol that is required by LSD includes the recording of 1D 1H and 13C as well as 2D COSY, HSQC and HMBC spectra. The status of each atom must be defined. It includes the atom symbol, the hybridization state (sp3, sp2 or sp), the number of attached hydrogen atoms, and the electric charge. This part of the data set is most often easily deduced by the user from elementary chemical shift knowledge. The status of the heteroatoms is deduced from the elemental molecular formula.

The CASA (Computer-Aided Spectral Assignment) program is intended to assign 13C NMR resonances to the carbon atoms in a user-supplied molecular structure.

It relies on an exploitation of chemical shift correlations in 2D NMR spectra and, optionally, on a comparison between experimental and estimated chemical shift values. The assignment of all resonances is possible if the hypothetic supplied structure is the good one, assuming that CASA input data is correct. CASA may therefore be seen as a 1D/2D NMR-based automatic structure verification tool. The result of the CASA program is a set of lists of possible assignments.


iNMR 5.3.6 released


The very popular NMR application iNMR was updated recently to version 5.3.6. This is a minor update:

When the slider for the first-order phase correction reaches the end-of-the-run, a message appears at the center of the same dialog: "Move This!", meaning that, if you want to go further, it's enough to touch the "fine-coarse" selector.

I’ve updated the spectroscopy page to reflect this


rNMR added to spectroscopy page


rNMR is an add-on for R.

rNMR is an open source software package for visualizing and interpreting one and two dimensional NMR data. In contrast to most existing 2D NMR software, rNMR is specifically designed for high-throughput assignment and quantification of small molecules. As a result, rNMR supports extensive batch manipulation of plotting parameters and has numerous tools for expediting repetitive resonance assignment and quantification tasks.

I’ve added it to the spectroscopy page.


Spectroscopy apps for iOS


I’ve just been sent details of a number of iOS apps that would be useful to those involved in spectroscopy, (NMR, IR, MS) so I’ve added them all to the mobile science site.




Learn NMR FID is a great teaching tool to learn the basics of NMR data collection and processing. Use simulated free induction decays (FIDs) and spectra to see apodization, noise and relaxation effects. Move peaks and see how the FID changes. Real and imaginary FIDs prior to and after processing are displayed as is the resultant spectrum after the Fourier transform.

There are more science apps for iOS on the mobilescience site.

I also thought I’d mention this framework that was brought to my attention recently. There is a trend to move massively parallel tasks to the GPU, GPU Image is a framework (BSD license) that simplifies the creation of GPU filters. This framework is built around OpenGL ES 2.0, so it will only work on devices that support this API. This means that this framework will not work on the original iPhone, iPhone 3G, and 1st and 2nd generation iPod touches. All other iOS devices are supported.


ChemDoodle Web Components 6 released

iChemLabs have just announced the release of ChemDoodle Web Components 6, this is a major update to their javascript based chemical structure drawing and rendering package.

One of the most important changes from a developers point of view is the external libs (jQuery, jQuey UI, jQuery plugins, glMatrix) are now included into the ChemDoodle scope. This offers several advantages, including eliminating all library conflicts, reducing the number of files required to be installed, and controls the versions used by ChemDoodle. You can now include these libraries yourself at any version and not worry about conflicts. To use the libraries inside of ChemDoodle, call them from the ChemDoodle.lib closure. When I created the interactive graph using FLOT this was one of the issues.

There is also a new EditorCanvas3D canvas which is the 3D component allowing you to interact with and alter chemical data as the 2D Sketcher does in 2D. The 3D editor supports many new WebGL features including picking, highlighting and measurements (distances, angles and torsions).

Lewis Dot Structure style bonds can now be rendered.

As well as editing and drawing structures ChemDoodle web components provides an means to simulate NMR and mass spectra in a web browser

There are also a number of bug fixes and other improvements.

Please Note

This update includes some major refactors, such as the renaming of the sketcher files and packages and inclusion of the external libraries internal to the ChemDoodle scope, so pay careful attention when upgrading.


iNMR Offers

I see the developer of iNMR has a number of opportunities to win copies of the excellent iNMR.

Details are here.

As we come up to the start of a new academic year there are also a couple of student promotions.


There are more spectroscopy applications here.


Overview of SCM tools

It is sometimes difficult to keep the website up to date with some of the software that I don’t use and so I was delighted when Fedor Goumans contacted me to highlight some of the updates at Scientific Computing and Modelling. While ADF is still SCM's most widely used program, SCM offers a comprehensive modelling suite consisting of several different tools.


I have written a brief overview here.

Here is a list of the reviews available.


ChemSpider and spectral information

There was an interesting entry on the ChemSpider blog this week, apparently they are starting to capture spectral information

The RSC now encourages authors for several of our journals to supply extra information, structures and spectra in their original file formats – which are attached to the article as supplementary information. Already we’ve seen several submissions of data that we have incorporated into ChemSpider records, both enriching the ChemSpider database and also showcasing the research of these authors through their publications. In this way, the RSC hopes to encourage the addition of reusable data files to the research paper as the start of its efforts to promote increased data sharing within chemical science research. In a few short weeks we’ve received a number of submissions from authors that include key chemical structures as mol files and in some cases extra data including 1H and 13C NMR spectra as well as UV and IR spectra.

As you can see from this entry ChemSpider ID: 28945607 there are spectra associated with this record. unfortunately at the moment you can’t view them in Safari because the javascript looks for Internet Explorer and Firefox. Fortunately you can get around this by changing the user agent from the “Develop” menu in Safari.


Once you have done that you can see the spectra displayed using a Java applet.




Accept-NMR uses an input PDB file, generate symmetry-related copies of a biological molecule of interest, and predict specific user-defined classes of intermolecular contacts between these (using a user-defined distance cutoff). Sort and analyze the resulting contacts, and visualize the results using several visualization schemes in PyMOL. Predict NMR spectra, and specifically the positions of intermolecular contact cross-peaks, based on the contacts predicted and chemical shift table. It is written in Perl, utilizing Gtk2-Perl bindings to provide a cross-platform compatible graphical user interface,

Added to the Spectroscopy page.

iNMR Reader for free

I noticed this in the iNMR newsletter.

FREE FOR EVERYBODY Only today 22nd Feb, anybody can ask for a free key for iNMR reader 5. No questions asked. iNMR reader 5 is a 64-bit application that requires Snow Leopard (or a later OS).

iNMR website

A new iNMR reader is available after many months. Instead of restarting from the old version, I have started from the full edition(which includes CPM, DOSY, relaxation times and many other things missing in the old reader), from which I have removed just three commands: Save, Export and Console. In practice it's the iNMR you have appreciated in the past year at a much lower price. Another thing that changes is the key: the old key isn't good. If you already have a license, please wait until March to install this new version and ask for the key. There is no upgrade fee to pay, but remember that a disposable license can't be moved to another computer. You will receive the key valid for your old computer. To ask for a new key, please send the old one back.


Collaborative Computing Project for NMR updated

The Collaborative Computing Project for NMR was updated last night. No details are available.

The Collaborative Computing Project for NMR (CCPN) is a project that aims to bring together computational aspects of the scientific community involved in NMR spectroscopy of biological molecules, especially those who work in the field of protein NMR. The CcpNmr software suite is a series of programs for macromolecular NMR spectroscopy integrated with the CCP data model. Between programs written by the CCPN, external contributions, and ‘outside’ programs integrated with the data model, it is the intention to provide one suite of programs to carry out all tasks needed in macromolecular NMR spectroscopy. The nature of the data model guarantees that any other program or suite that interfaces with the data model can be used alongside or instead of the CcpNmr suite.

CCPN will be giving a demonstration at the EUROMAR conference during the first week of July (see They will also be handing out CDs with the latest release.

There is a page of spectroscopy applications for Mac OS X here.


iNMR 5.2.4 released

The latest Mac version of iNMR is 5.2.4, released today. Due to popular demand it restores the slider for zero-order phase correction, which reappears side-by-side with the knob that has been in its place for a whole year. Their function is equivalent. This seems to be a case where it's better to have redundant controls.


Added pycifrw to spectroscopy page

PyCIFRW provides support for reading and writing CIF (Crystallographic Information Framework) files using Python. PyCIFRW is written entirely in Python. While this makes parsing of large CIF files rather slow, it will run wherever Python runs.

Now added to the spectroscopy page


iNMR Updated

iNMR has been updated to version 5.2. This version supports Mac OS X 10.6. 10.7 and 10.8.

I’ve also updated the spectroscopy page.


iSpartan and iSpartan server

I was wondering when someone would use an iPad as the front-end to a fully featured modelling package running on a remote server, looks like Wavefunction have done a pretty impressive job with taking their sophisticated Spartan computational chemistry package from the desktop to mobile devices.

iSpartan creates molecules as familiar 2D sketches, directly converts these into 3D structures, and calculates low energy conformations. Atomic and molecular properties, NMR and infrared spectra, molecular orbitals and electrostatic potential maps are available from a 5,000 molecule subset of the Spartan Spectra and Properties Database (SSPD). The database may also be searched by substructure. Properties, spectra and graphical models of molecules in the SSPD subset are available for examination.

iSpartan Server is an available add-on to the iSpartan app. iSpartan Server installs on a Windows or Macintosh computer and converts iSpartan from an application whose primary utility is sketching molecules in 2D and visualizing them in 3D, into an open-ended molecular modeling research tool providing access to the full Spartan Spectra and Properties Database (SSPD), currently ~170,000 molecules) and to the computational engines used to produce the data in the SSPD. For molecules not included in the database, connection to iSpartan Server supports calculation of structures, properties, and spectra for all user generated molecules from iSpartan running on the iPad, iPhone, and iPodTouch.
