FILE TYPES SUMMARY
Codamotion Analysis and MDB Report Generator
MDF 'Movement Data File'
Binary-format files containing 'raw' movement data including marker positions, force-
plate data (as analogue input channel data [8 channels per plate]), and EMG data (in
groups of 8 channels). Also includes text Comments data and cursor positions, and
Subject/Patient data (if any). May also include video (AVI) data.
MDF files can be read only by Codamotion Analysis (and the MDB Report
Generator).
File format information can be supplied by Charnwood Dynamics for programmers
wishing to read these files directly.
STP Setup file
ASCII text-format file storing the Codamotion Analysis Setup configuration for a
movement analysis project.
Created from Codamotion Analysis with the Setup: Save Setup... command.
Read only by Codamotion Analysis (not the MDB Report Generator).
Can be inspected, edited, or printed with any text editor. The file is organized into
named sections. Some of the entries are easily interpreted, but some are not - the
graph definitions for example. Great care must be taken if an attempt is made to edit
a Setup file, as an invalid entry may cause Codamotion Analysis to crash when the
Setup is loaded - it is not able to ignore all types of invalid entry.
MDR 'Movement Data Report' file
An extension of the MDF file format which includes calculated (segmental analysis)
data (calculated by Codamotion Analysis).
This extra data is required by the MDB Report Generator to produce segmental
analysis report graphs (the Report Generator does not calculate anything for itself).
The calculated data channels are labelled in the MDR file with the names defined for
the channels in the current Setup configuration. These names are referred to in the
MDB Report Generator Graph definition formulae.
An MDR file is created by Codamotion Analysis when the File: Save As... command
is used, and items are checked in the 'Calculated Data' options list.
MDR files can be read only by Codamotion Analysis and the MDB Report Generator.
