Revision as of 17:26, 16 February 2010
There is a compelling need for improved software systems for delineating the C."elegans" worms in time-lapse image sequences and tracking their movements. Segmentation and tracking provide the basis for making quantitative measurements of worm morphology, and various aspects of their dynamic behaviors. To facilitate the quantitative studies of worm behaviors, we developed a automated worm analysis system which is open-source and could be adopted by all researchers in the c."elegans" community.

System Overview
Figure1 shows a screenshot of the main window of the system.
- Menu: the menu provides operations like file operations and editing operations which allow user to edit (reverse, delete and correct)selected worms in the tracking window.
- Toolbar: the toolbr provides three buttons for controlling the tracking process. Users can pause tracking at any timepoint and
do some observation or interactive editing when necessary. The thrid button make it possible for the user to start tracking from any saved tracking result which stores worm shapes, features and identities. Thus the user don't need to start over the tracking if the program was closed normally or abnormally.
- Input and Output: the input and output section allows users to specify the directory of image sequence and the directory for storing tracking result. For each frame, the tracking result of it includes a txt file storing the worm structure(centerline and contour points), a excel file storing extracted features(motion state, shape and motion features, events, etc.) and a png image saved from the tracking window. The results could be explored at anytime during or after the tracking.
