1. When the Database Dialogue windows opens, check that its title bar indicates that the
appropriate database (PDB) file has been opened. There are different database files for
Segmental and External gait analysis reports; the program automatically loads the last-
used database file.
[xx_SG01.PDB for segmental analysis; xx_XG01.PDB for external gait analysis.]
(The pdb database file includes the graph definitions for the report.)
2. Click the Open button on the Dialogue and select your MDR data file(s) (one at a time).
You may need to change directory in the ‘Folders’ part of the dialogue.
(If the file was saved from Codamotion Analysis with a different filename extension,
select ‘*.MDF’ or ‘*.*’ in the ‘List files of type’ pull-down listbox.)
Any number of files may be opened at the same time. Normally a report includes only
one Left, one Right, and possibly one Normal datafile, although any number of files
may be included. (In which case, all Left data will be plotted in blue, all Right data in
red, and all Normal data in grey.)
3. Click the Add File(s) to Database button
(The file(s) must first be highlighted.)
This copies the gait-cycle parameters from the files into the internal database and
opens the Data Files table window.
4. Close the Data Files table window - it is not needed.
(Click the X control on the window’s title bar.)
5. Select the files in the Active Data Files list (if they are not already highlighted):
A file must be highlighted for its data to be included on the report graphs.
Click on each filename to select or de-select it.
6. Click the Reports button and select a report format from the list:
‘All file data’ gives graphs of all cycles, annotated in time (with the marked gait cycle
indicated).
‘Cycle Symmetry’ gives graphs of only the marked gait cycle (for each file), annotated
in percent.
WARNING! Don’t select an ‘External: ...’ report when an ‘SG’ database is open, and
don’t select a ‘Segmental: ...’ report when an ‘XG’ database is open - there won’t be
any graphs.
7. Click the View button.
This opens a Report View window in which the report may be viewed in detail if
required (maximize the view), but it is usually better to use File: Print Preview to
check the report (step 9).
