"GEnerator of atomic COORdinates for armchair nanotubes with specific bond lengths and angles. (gecoor) Gustavo Domínguez Rodríguez, Gabriel Iván Canto Santana, Jorge Alejandro Tapia Gonzalez, Cesar Alberto Cab Cauich A problem that arises when applying specific strain fields to nanostructures is knowing the atomic coordinate positions that produce the required structural parameters, such as bond lengths and angles. Due to this, a simple-to-use program is implemented within a command-line, for both Linux and MS Windows environments, to generate atomic coordinate files for later use in first-principles simulation codes. ...

VASPMO aims at visualizing wavefunctions (or molecular orbitals) from VASP calculations. It reads VASP's output files PROCAR and CONTCAR, and exports an *.out file in Gaussian's output format, which can be visualized by many popular visualization tools, such as JMol, Molekel, Chemcraft, Gabedit and Molden, etc. These tools can further generate *.cube files, which can be visualized by an even wider range of...

...The few freely available software packages limit their output to a subset of the possible configurational space by sometimes unwanted prior assumptions and complete neglection of ring-chain tautomerism. MolTPC provides an adjustable and fully automatic approach for this problem. The original publication can be found on http://onlinelibrary.wiley.com/doi/10.1002/jcc.23397/full.

RASP uses structure-based chemical shift predictions to solve the backbone resonance assignment problem in protein NMR spectroscopy. This enables rapid determination of highly accurate assignments on the basis of minimal experimental datasets, even for spectroscopically challenging proteins. RASP takes as input spin systems assembled on the basis of an arbitrary set of conventional triple-resonance NMR experiments. Uniquely, RASP is capable of extensive assignments even in the abscence of Cbeta chemical shift information: over a test set of 154 proteins RASP assigns 88 % of residues with an accuracy of 99.7 %, using only information available from HNCO and HNCA spectra. ...
