Task Manager with FlyLimbTracker NPE error

[snznpp]

Hello all!

I recently downloaded the older version of icy (1.7.3.0) to use the FlyLimbTracker plugin developed here: http://bigwww.epfl.ch/algorithms/FlyLimbTracker/

The plugin works perfectly, however, I am having issues with Track Manager. When I click on the button that connects FlyLimbTracker with the Track Manager, called "compute snake tracks" I get the error message "java.lang.NullPointerException" followed by Icy crashing.

Can you please help? Is this an error which I can fix? I have the latest version of Java which is suitable for my 64 bit Windows OS called JRE-8u-121.

Cheers,

Sinzi

Hello Sinzi,

Digging in the General bug report i saw these reports :

java.lang.NullPointerException
	at splineSnakeHandler.cleanUp(DropSnake_.java)
	at splineSnakeToolbar.mousePressed(splineSnakeToolbar.java)

 java.lang.NullPointerException
	at imageaccess.ImageAccess.<init>(ImageAccess.java)
	at Image.<init>(Image.java)
	at DirDerrivative.<init>(DirDerrivative.java)

	at Snake.<init>(Snake.java)
	at splineSnakeToolbar.mousePressed(splineSnakeToolbar.java)

java.lang.NullPointerException
	at splineSnakeToolbar.mousePressed(splineSnakeToolbar.java)

It looks like the error happen in the Snake plugin, you should try to contact the developers from the homepage:

Pointing them these error log could help them in resolving the issue.

Best,
