RData2 ASCII conversion software

"Thanks again for all of the work you and your people did for us on the RData2 program, it truly reduced a monumental task, to a single day's work!! I can't thank you enough! Once I had all of the files set up, things ran smoother than I had anticipated. It took the computer about 40 minutes to export just over 1200 files." - Joe Van Bogart (Medical College of Wisconsin).


The evaluation version of RData2 is fully functional on all file types so long as the input data has less than 100 frames. The registered version operates on any file length and is supplied with a detailed manual and full support for a year. Contact us for information about registering this product.

32/64 compatible - this program runs on any 32-bit or 64-bit Windows operating system.

RData2 is an inexpensive program that reads and converts more than a dozen different biomechanics data file formats, from different manufacturers, into standard ASCII text files. Unlike other ASCII conversion programs, RData2 is very fast and can be run automatically, taking its input files from a list and converting the data to ASCII without any user input. RData2 enables any researcher or student to access the raw data that their Motion Capture system generates - all without requiring any programming skills. The ASCII files produced by RData2 can be read with virtually any program such as Excel, SAS and Word etc.

RData2 can be run both as a regular Windows GUI-based program or incorporated into Excel spreadsheets, Access databases. Using the command line interface feature, RData2 can be called from within Visual Basic programs to automatically extract data from any C3D or other supported file format. This makes RData2 one of the most versatile ASCII export programs available. Naturally, as a Motion Lab Systems product it includes full support for the export of data and parameters from any C3D file.

In addition to converting the input data, RData2 also allows the user to browse the binary file data and parameter types to see exactly what information is available. The user has complete control over the selection of data items that will be converted to ASCII. Data selections can be saved and then become the default for the next set of data conversions. RData2 is an easy-to-use graphical, 32-bit Windows program that offers every user the ability to define their own output file format as an ASCII text file (TXT output) or standard DST format. RData2 exports original binary data to either, a standard DST format (supporting several different lexicons), or an ASCII text format that offers a wide variety of formatting options that are completely controllable by the user. Either format can be set as the default.

Administrative rights are only required during installation - the application can run at a standard user privelege level.

RData Input File Formats

RData Output File Formats

DST file format - DST files are ASCII files that use a format developed and standardized by CAMARC (the acronym means Computer Aided Movement Analysis in a Rehabilitation Context). This is a deceptively simple output format that can be used to document almost any data but is especially suited to biomechanics data. As a CR/LF delimited format, DST file can be rather large and inflexible but have the advantage that they are relatively easy for people to read. Download our companion DST file viewer application if you need more information or would like to view the contents and structure of DST files.

VDO lexicon - This is a DST file definition that is read by GaitLab 2.0 - an interactive software package that teaches Gait Analysis (Vaughan, Davis, O'Connor). RData2 can generate GaitLab 2.0 compatible files from any C3D file that contains data conforming to their Kinematic model. Links to this software and other commercial software packages can by found on our links page.

RRD lexicon (Whisper) - This is the lexicon used by the Roessingh Research and Development EMG evaluation software that is included with the Whisper EMG Tester. It can be generated from C3D, ANA and WDQ files.

MLS lexicon - A standard DST lexicon that allows data from C3D files to be stored in ASCII. Complete details of these formats are available in the RData2 manual (supplied with registered copies of the program).

TXT format - The standard TXT format produced by RData2 is a flexible ASCII format that is completely under the users control. This option allows the user to produce a wide range of different output formats to suit specific applications or research issues. These formats are reproducible and can range from a simple "data with header line" to complex formats that include every scrap of information in the original file. Using RData2 in to generate TXT output is a viable alternative to writing your own code to access many binary file formats.

Students can use RData2 to extract any information directly for a C3D file without any complex programming or debugging. RData2 allows you to concentrate on the meaning of the data - not the file format!

RData2, like all Motion Lab Systems applications, is a site licensed application. The purchase of a single RData2 license allows multiple copies of the software to be used within any given environment, permitting its use on multiple computers, laptops etc., making it very easy to use in academic and research environments without any hardware access keys or restrictive licensing requirements.
