LMAPper - The SPM and Mol Viewer
Where SPM images and molecular models meet
...It is useful to understand how your molecules fit to what you observed and can help interpret your data. What makes this application more useful than paint programs (powerpoint or inkscape) is the fact that the size of the images and of the molecule is fixed, so that you know that you are working in real space. Check https://sourceforge.net/p/spm-and-mol-viewer/wiki/Home/ for updates. -

ParamIT
a Toolset for Molecular Mechanical Force Field Parameterization
...The developed toolkit helps the researchers in following ways: 1) automating the creation of multiple input files for quantum and molecular mechanics programs, 2) automating the output analysis and 3) substitute the use of full MM programs with a faster specialized one. The developed tools include: 1) generator of molecule-water complexes with graphical user interface (GUI), 2) semi-automatic frequency analysis using symbolic potential energy distribution matrix and comparison of optimized internal coordinates, 3) GUI for charge fitting with three modes: manual, Monte-Carlo sampling or brute force, and 4) GUI for dihedral terms fitting. The usage of these tools decreases the labor effort, lowers manual input errors and reduces the time needed for accurate MM parameterization efforts. -

easy-dhpsf
GUI for fitting 3D single-molecule images using the double-helix PSF
...Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs -

ConvertMAS
ConvertMAS converts Chemical File Formats mol, mol2 and sdf.
ConvertMAS - molecule converter; use to convert Chemical File Formats. It works on mol, mol2 and sdf files. It converts single file to respective formats. It will split sdf file with multiple molecules into seperate single files of any desired format. Also ConvertMAS creates sdf files from joining of mol, mol2 and sdf files. This is stand alone application; hence no need of internet connectivity to get results. -

javadbchem
A universal chemistry database system, using Java and any rdbms
...The system holds atoms and bonds as entities in the rdbms, this makes it possible to have properties recorded using foreign keys and referential integrity. Apache Torque is used for database access. The build system of the project makes it possible to add properties directly to the molecule/atom/bond tables. This makes it more flexible than systems where structures are saved as monolithic blobs in a single table. -
