Free file formats software for linux

GNOME Structured File Library is a utility library for reading and writing structured file formats. Support for MS OLE2 streams is complete, as is zip import.
There is also support for document metadata and some initial work on decompressing VBA streams in OLE files for future conversion to other languages.
This library replaces libole2 and is used in gnumeric, mrproject, abiword, libwv2, koffice. It is also part of the AAF format.
Enhancements:
- This release reverts jump to dynamic types, as they arent thread-safe.
- A compilation glitch on Windows has been fixed.
- Problems building without gconf macros installed are avoided.
- Configure breakage with --without-gnome has been fixed.

libgsf aims to provide an efficient extensible i/o abstraction for dealing with different structured file formats.

Open Babel project is designed to pick up where Babel left off, as a cross-platform program and library designed to interconvert between many file formats used in molecular modeling and computational chemistry.
Main features:
- A huge variety of common chemical file formats, including SDF/MOL, Mol2, PDB, SMILES, XYZ, CML... (details)
- Recognition of file type based on filename extension
- Chemical MIME support
- SMARTS matcher
- Flexible atom typer
- Flexible bond typer for perception of multiple bonds from atomic coordinates
- Gasteiger partial charge calculation
- Hydrogen addition and deletion
- Isotope support, calculation of average and exact masses
- Automatic feature perception (rings, bonds, hybridization, aromaticity)
- Multiple conformer storage within molecules
- Command line conversion for multiple molecules in one file
- Command line interface
- Bitvector class
- Vector and matrix transformations
- Molecular test suite
- Open-source/Free Software under the GNU General Public License
- Cross platform (Windows, Linux, Mac OS X, SGI, Solaris, Dreamcast...)
Version restrictions:
- Generate coordinates for SMILES strings. (Meaning all coordinates will be zero when converting from a SMILES string.)
- Handle 2D->3D conversion (or vice versa).
- Handle a variety of important file formats.
Whats New in 2.1.1 Development Release:
- Improved scripting support, including dictionary-support for OBGenericData in pybel, casting from OBUnitCell, etc. Improved access to OBRings from OBMol.GetSSSR().
- Added support for descriptors (e.g., PSA, logP) from scripting interfaces.
- Added support for reading all PDB records (beyond current atom and bond connections). Records not handled directly by Open Babel are added as key/value pairs through OBPairData.
- Added a new configure flag --with-pkglibdir to allow Linux package distributors to define version-specific directories for file format plugins.
- Fixed a bug which would not output chirality information for canonical SMILES with 3D files.
- Fixed problems with new line-ending code. Now correctly reads DOS and old Mac OS files with non-UNIX line endings.
- Correctly rejects SMILES with incorrect ring closures. Thanks to Craig James for the report.
- Fixed a crash when output to canonical SMILES.
- Fixed a crash when converting from SMILES to InChI.
- Fixed a crash when reading some PDB files on Windows.
- Fixed a crash when reading invalid MDL/SDF files.
- Fixed a bug which made it impossible to read some GAMESS files.
- Fixed a problem when reading ChemDraw CDX files on Mac OS X.
- A large number of additional fixes, including some rare crashes.

OmegaT is a free translation memory application written in Java. It is a tool intended for professional translators. OmegaT does not translate for you! (Software that does this is called "machine translation", and you will have to look elsewhere for it.)
Main features:
- Fuzzy matching
- Match propagation
- Simultaneous processing of multiple-file projects
- Simultaneous use of multiple translation memories
- External glossaries
- Document file formats: plain text, HTML, OpenOffice.org/StarOffice (the latter has excellent conversion filters for MS Word, Excel, RTF)
- Unicode (UTF-8) support: can be used with non-Latin alphabets
- Compatible with other translation memory applications (TMX Level 1)

VFGEN is a Vector Field File Generator for differential equation solvers and other computational tools.
There are many excellent programs available for solving differential equations and computing bifurcations of vector fields. However, each has its own format for specifying the vector field that defines the differential equation. VFGEN lets you define your vector field once (using XML), and export the vector field in several formats. VFGEN uses a C++ symbolic algebra library (GiNaC) to generate Jacobians and higher derivatives automatically.
Main features:
- Specify your equations once, and export to multiple file formats.
- Generate analytical expressions for Jacobians and higher derivatives automatically.
- Available export formats include MATLAB, Scilab, AUTO, GNU Scientific Library (GSL), SciPy, PyDSTool, XPP and more.
- New in Version 2.1.0: Octave, PyDSTool and RADAU5 commands added.
- New in Version 2.0.0: VFGEN can generate code for delay equations.

SlimServer on DiskStation is an add-on package to the Synology DiskStation family of PowerPC based NAS devices providing the environment to run SlimDevices SlimServer on it.

This project integrates into the DS administrative Web interface and comes with various user-friendly tools and scripts to maintain the installation.

It supports all currently official features of Slimserver, such as Asian character display and on-the-fly transcoding of various music file formats. Popular third party plugins are supported as well.
