BioXTAS RAW is a program for analysis of Small-Angle X-ray Scattering (SAXS) data. The software enables: creation of 1D scattering profiles from 2D detector images, standard data operations such as averaging and subtraction, analysis of radius of gyration (Rg) and molecular weight, and advanced analysis using GNOM and DAMMIF as well as electron density reconstructions using DENSS. It also allows easy processing of inline SEC-SAXS data and data deconvolution using the evolving factor analysis...

Even in the simplified two dimensional HP-model (hydrophob/polar) the prediction of proteinfolding is NP complete. We implement a brute force algorithm with serial and parallel execution to solve short inputs of HP sequences (0-1 bitstrings). Selbst im vereinfachten zweidimensionalen HP-Modell (hydrophob/polar) ist die Proteinfaltung bereits NP-vollständig. Hier implementieren wir einen brute-force Algorithmus zur Lösung kurzer Eingabesequenzen (0-1-Bitstrings) für die Proteinfaltung.

...The program DATASW performs averaging of individual data frames from HPLC-SAXS experiment using a sliding window of a user-specified size, calculates overall parameters (I(0), Rg, Dmax and MW) and predicts the folding state (folded/unfolded) of the sample. Applications of DATASW are illustrated for several proteins with various oligomerization behaviors recorded at different beamlines.

RSchr-5 calculates the smallest eigenvalues of the one-electron Schrödinger equation. The solved problem is defined on the finite domain, which is a box. The problem is solved with the zero Dirichlet boundary conditions. The implemented algorithm uses Finite Element Method with B-splines as basis functions. Disctretization leads to generalized eigenvalue problem. Program RSchr-5 solves the generalized eigenvalue problem by algorithms implemented in SLEPc amd PETSc libraries. It uses Krylov-Schur algorithm from SLEPc library. ...

A Windows software for generating structures of nanotubes and some fullerenes. You can generate any kind of nanotubes (n,m) with chirality indices n and m ranging from 0 to 60, and the number of repetitive unit cells up to 50. You can also generate some typical fullerene cages from C20 up to C320.

...ANT.Gaussian (or ANT.G for brevity) relies on the popular quantum chemistry code GAUSSIAN03/09 code with which interfaces in a seamless manner. Straightforwad use of ANT.G include the computation of the zero-bias conductance (or, alternatively, the electrical current under an applied bias voltage) of a variety of nanoscale systems such as molecular bridges or simply metallic atomic contacts as those created with scanning tunneling microscope or break junction techniques. The use of ANT.G may also be naturally extended to the computation of scanning tunneling spectroscopy and the simulation of scanning tunneling and electrostatic force microscopy.
