CheckMol/Matchmol

Checkmol is a command-line utility program that reads molecular structure files in different formats and analyzes the input molecule for the presence of various functional groups and structural elements. At present, approximately 200 different functional groups are recognized. GPL licensed.

Matchmol complements the capabilities of checkmol. It compares two (or more) molecular structures and determines whether one of them is a substructure of the other one. GPL licensed.

CyberUnits

CyberUnits is a collection of cross-platform units for medical cybernetics and systems biology. It supports Object Pascal, S and Matlab.

DMV

DMV The Diffusion Model allows for modelling response times. The Diffusion Model Visualizer explores the effect of the seven model parameters (a, z, v, t0, sz, sv, and st0) upon the response time density curves and positive/negative response probabilities. It supports interactive parameter change with immediate update of the diagram. The diagram can be stored to disk for further use (e.g., in an article or educ=ational context). The program is freeware.

Foobot Monitor

  • Foobot(http://foobot.io/) is an InternetOfThings gadget that monitors indoor air quality
  • Unfortunately, the company currently only supplies mobile phone apps to access the Foobot
  • They do however publish an API which returns JSON data when queried, so I decided to port it to the PC using Lazarus and FPC
  • Wiki Page: Foobot

What you will need: A Foobot, a Foobot account, a free API Key (get one from the API page: https://api.foobot.io/apidoc/index.html)

FREE!ship Plus in Lazarus

FREE!ship Plus in Lazarus is further development of the FREE!ship Plus Windows program based on the free source code FREE!ship v3.x under GNU GPL license. This FREE!ship Plus application is migrated into free open source Lazarus / Free Pascal environment to promote further development in various platforms and for various platforms (OS and architectures).

FREE!ship Plus is designed for the full parametric analysis of resistance and power prediction for a ship and other calculations of hydrodynamics of vessels and underwater vehicles. FREE!ship Plus allows the designer to simulate and analyze condition of balance of a complex completely hull - rudders - keels - engine - propellers in different regimes and of service conditions of a ship. The analyzable system includes a hull, appendages, a propeller and the engine (i.e. resistance, power, a thrust and a torque), and also various service conditions (heaving, a wind, a shallow-water effect, a regime of tow / pushing, etc...).

Grid InQuest II Coordinate Transformer

The Grid InQuest II desktop application and command line tools provide a means of transforming coordinates between global geodetic coordinates (ETRS89/WGS84) and the national systems of Great Britain and Ireland. It provides a fully three-dimensional transformation incorporating the latest geoid model (OSGM15) and the appropriate polynomial transformation model (OSTN15 or OSi/OSNI) for each of the projected coordinate systems. This was developed in Free Pascal and Lazarus by Michell Computing. It was commissioned jointly by the Land and Property Service of Northern Ireland, the Ordnance Survey of the Republic of Ireland and the Ordnance Survey of Great Britain.

i6z Toolkit

The i6z Toolkit is a Graphical User Interface (GUI) application for handling IUCLID 6 archives (i6z). The IUCLID (International Uniform ChemicaL Information Database) software application is developed by the European Chemicals Agency (ECHA) in association with the Organisation for Economic Co-operation and Development (OECD). The i6z Toolkit allows users to manipulate such archives, mainly in the areas of previewing and file management/organisation. Conveniently, this is done without the need to run the IUCLID 6 application.

The i6z Toolkit is available for MS Windows, macOS, and Linux.

LazBacterias

LazBacterias is a program to simulate the growth of bacterial cultures using the rules of Conway's Game of Life.

LazStats

LazStats is a free statistical analysis program written in Lazarus by Bill Miller. It contains a large variety of parametric, nonparametric, multivariate, measurement, statistical process control, financial and other procedures. One can also simulate a variety of data for tests, theoretical distributions, multivariate data, etc.

The most recent sources are available at the Lazarus Code and Component Repository.

MRIcroGL

MRIcroGL is an opensource project that uses the graphics card (using OpenGL) to visualize and volume render medical images. It is hosted on the National Institutes of Health (NIH) Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC). It can view images saved in NIfTI (.nii, .nii.gz, .hdr/.img), Bio-Rad Pic (.pic), NRRD, Philips (.par/.rec), ITK MetaImage (.mhd, .mha), AFNI (.head/.brik), Freesurfer (.mgh, .mgz), and many DICOM (extensions vary) formats. It is available for Windows, Linux and macOS.

Nest-o-Patch

Nest-o-Patch, software for the analysis of patch-clamp, two-electrode-voltage clamp and other electrophysiological data. Directly works with files created by HEKA Pulse or Patch-Master data aquisition software or with CSV and text files. Designed mostly for the analysis of single channel recordings, was nevertheless successfully used for whole-cell data analysis. Several academic papers were published with the use of this software.
