windows default iconMokka Publisher's description

Mokka is an open-source motion analyzer software that can read, edit, write and visualize motion capture data (trajectories, model outputs, events, analog, force-plates).

Mokka is an open-source motion analyzer software that can read, edit, write and visualize motion capture data (trajectories, model outputs, events, analog, force-plates).
Mokka is especially designed for movement science applications like gait analysis, biomechanical research, sport analysis…
Mokka is compatible with several file formats used in biomechanics:
C3D file format: http://www.c3d.org
TRB file format: Motion Analysis
TRC file format: Motion Analysis
RAH file format: BTS Bioengineering (Elite)
RAW file format: BTS Bioengineering (Elite)
RIC file format: BTS Bioengineering (Elite)
Mokka uses the file format MVC (Mokka Model Visual Configuration) to configure the visual aspects of the acquisition (markers' color, markers' size…)
Mokka loads automatically a visual configuration when you open an acquisition file with the same name (try to load it from the list or from the acquisitions' folder).
Mokka is able to receive file dragged and dropped from your file browser to the 3D view.

What's New in This Release:

New Features:
· New file format: XMOVE
· New file format: MDF
· New file format: Delsys EMG
· New file format: CLB
· New plot options to draw cyclic data into a chart.
· New update manager: you won't need to go on the net, close Mokka, download the new release, unzip it and copy it. Everything is automatic!
· New menu "Tools" to regroup all the editing actions (reframe, clear events, etc.).
· New tool to create an average marker from a selection of markers (real or virtual).
· New tool to detect heel strike and toe off events during gait.
· New tool "Filter Analog (Butterworth)"
· New tool to smooth analog signal using moving RMS windows and moving average window.
· New tool to rectify the content of analogs channels.
· New tool to remove analog offset.
· New category in the acquisition explorer to show "Virtual markers" (useful for Vicon C3D file).
· New static way to add markers in the category "Virtual markers".
· New function "Reset all Zooms" in the context menu of the charts views. Set all charts' axes to their original range.
· The list of filters (extensions) in the open/save dialog box box is now sorted.
· New preference to set the back color of the ground.
· New reload button as suggested on UserVoice.
· New shortcuts to insert events (Alt 1-9).
· Create an option in the import assistant for videos only.
· Move automatically the time cursor when you click on the time bar.
· Option to change the background color.
· Record the position (pose and zoom) of 3D windows.
· Display the angle between two vectors.
· Display the angle between three points.
· Display the distance between 2 markers.
· New assistant to create segment as a set of links and faces.
· Add an export assistant to save any data in an ASCII file.
· New exporter to create STL files from a selected segment.
· New function to export 3D view as series of images.
· New action (File > Open File Location) to open the folder which contains the current acquisition.

Usability Improvements:
· Improvement of the C3D parser to be more flexible in the extraction of the parameters' data.
· The ground orientation for the TDF files is now automatically set (i.e Y axis vertical) as it seems to be the general behavior.
· The use of the Alt key in a chart view synchronize the mouse events (zoom, move) for all the charts inside!
· The menu to modify the playback speed is available even if no acquisition is loaded.
· The horizontal axis unit menu is also available in the contextual menu of each chart. Shortcuts were also added.
· The root for the model outputs and the force platform reactions in the acquisition explorer are now every time expanded if visible.
· The item's roots (Markers, Analogs, etc.) in the acquisition explorer are automatically expanded if only one is visible.
· If a plot has less than 40 points displayed, then a circle marker at each point is also displayed.
· The tests on files existence were moved from the loading of Mokka to potentially speedup the starting of the software.
· If the range of the Y axis in a chart is zero, then the range is increased by [-0.01:0.01].
· The maximum width of the acquisition explorer is increased under Windows and Linux.

Issues resolved:
· Removing a visual configuration and creating a new one crashes Mokka.
· Analogs' unit is not saved in the C3D file format.
· Issue 13: The rubber band in the 3D view is not correctly redrawn.
· The implementation of the writer for the TRC file format exports every points and not only markers.
· The content of the logger is wrongly painted/styled when Mokka loses focus.
· With two screens and Mokka on the second one, plots' options are not correctly located or not visible.
· Loading first a file, and then using the assistant doesn't display "No File" in the window title bar.
· Fix segment's flickering when a configuration is loaded and some segments are hidden.
· Wrong path when saving a file for the second time.
· The menu to modify the playback speed and the menu to insert events are disabled.
· Impossible to see the delete buttons used to delete plots (in chart/plots options) if the acquisition explorer is in floating mode.
· In the time event bar, the labels' tick can overlap on the other when the unit is the time.
· Using the action "Manage User Layout" under Windows doesn't show the chosen tab.
· Potential fix for a random bug in Mokka (GRFs are not reloaded and a buffer overflow happens if the new acquisition is longer).

System Requirements:

No special requirements.
Program Release Status: New Release
