This update is a minor update that will bring little changes to the program. It induces the introduction of some new features and some bug fixes. I) New features AnimalTA now proposes to make manual trackings: fill the table with NA values and let the user make the tracking manually. Now when a shape (ellipse, rectangle, polygon) or a circle is defined in the analyses, the program calculates various variables for the trajectories inside those shapes (i.e: speed inside the shape, prop time stopped inside, etc) Concatenation of concatenated videos is now possible. Export a video will now adapt the frame rate of the exported video to the reading speed defined by the user in the "export video" section. II) Bugs correction: If the videos were concatenated but not cropped, the tracking was not functional. --> fixed When using the "redo the track" option, the displayed frame after validating was not the correct one if the video frame rate was not the original one. --> fixed The meander value was underestimated by previous calculations. --> fixed The tracking process was sometimes especially slow (hours for a few minutes video). --> fixed It was sometime impossible to copy or rotate some arenas. --> fixed
