Enter a new filename: change the ‘MDF’ extension of the existing filename to ‘MDR’
(for Movement Data Report) to create a new file. (The current datafile name is show on
the main title bar.) Keep the first part of the name to 8 characters or less, and don’t use
spaces, even if you are using Windows 95 - the MotionDB report generator is a 16-bit
(Windows 3.1) application which doesn’t fully support long filenames.
If, on clicking OK, there is a warning that the gait cycle(s) have not been marked, click
‘No’ and go back to item 8: there must be three green (left) and/or three red (right)
cycle marks. (If you save the MDR file with insufficient cycle marks, you can generate a
report showing graphs of all cycles without any gait-cycle parameters, but you won’t be
able to generate a cycle-symmetry report.)
In the Data Save Options dialogue, select the calculated data types which are to be
plotted on the report: If Force-plate data is present and assigned as Left or Right, then
check all the boxes.
If there is no force data, or if it was ‘Undefined’, do not select the 3D Joint Moments or
Powers, as these will be invalid during ground contact.
If your data is to be used as ‘Normal’ data on a report, select the ‘Left’ or ‘Right’ check-
boxes.
If you intend to generate a report of all cycles and wish to remove the out-of-view data
at the end of acquisition, cancel the dialogue, zoom the data to exclude unwanted data,
then repeat Save As and check the ‘Save zoomed-in data only’ check-box. (Be aware
that this will give reports with varying time scales.)
12. Close the datafile and exit Codamotion Analysis:
If you have no more datafiles to process, exit Codamotion Analysis (File: Exit).
Alternatively, you may process the rest of your files before starting the Report
Generator.
You can leave Codamotion Analysis running, but it is best to close datafiles before
opening them in Motion Analysis Database.
Procedure II - in MotionDB Report Generator
There is a short delay after Motion Analysis Database opens while it reads the report
definition (RPT) files configured in the report.cfg file. (If there is no delay, the report.cfg file
and/or the RPT file(s) are missing from the working directory.)
Two types of file are opened by MotionDB: A Database (PDB) file and multiple Motion
Analysis Report (MDR) data files. The Database file is usually opened automatically
when MotionDB starts, but it can be opened, saved, and closed manually with the File
menu commands. Codamotion Analysis data files are opened with the Open button on
the Database Dialogue window.
