Where can I find the executable of GenPlay?
The jar files of the current as well as older versions of GenPlay are available in the Older Versions section of this website.
Where can I download the source code of GenPlay?
The source code of GenPlay is available from the SVN repository at https://genplay.einstein.yu.edu/svn/GenPlay You can check out the latest source codes with a SVN client with the following command:
svn co https://genplay.einstein.yu.edu/svn/GenPlay
During zooming, the item I want to zoom in on keep sliding off the edge of the display. How should I use the zoom functionality to avoid this problem?
During the conception of the software we decided to handle this problem as follow:
- A double click on a feature where he wants to zoom. This action will center the screen on the selected feature.
- The user wheels up or down with the mouse in order to zoom in or out. An unintended click on the mouse wheel starts the scroll mode which can be undesirable.
Since this comment was also made by other users we decided to create a FAQ page on our website showing the answer of this question.
When does GenPlay use multiple CPUs, and is it possible to add more threaded operations?
GenPlay uses more multiple CPUs for the operations only if the computer has more than two cores. When a threaded operation starts, the program checks how many cores are available, and dispatch the threads on each core but one which is kept for the operating system and the display of the GUI. Obviously, if the computer has only one core the operations are started on the same core has the GUI.
Does the software use the GPU, and is it possible to do so?
The software uses the Java 2D technology for the display of the GUI. A set of command line flags can be used with this technology, some of which can improve the performance by helping the software to fully benefit from hardware acceleration. Here is the Java web-page describing the different flags that can be set: http://download.oracle.com/javase/6/docs/technotes/guides/2d/flags.html
