Kymograph Error

[aurorachic]

Hi,

I am encountering problems with running the plugins including Stack Difference, Walking Average, Multiple Overlay and Multiple Kymograph.

For instance, using the Multiple Kymograph (or any of the other 3) plugin(s) will cause such a window to pop up:

Exception
java.lang.ClassFormatError: Incompatible magic value -1095041334 in class file MultipleKymograph_
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:675)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:520)
        at ij.io.PluginClassLoader.loadClass(PluginClassLoader.java:246)

        at ij.Executer.run(Executer.java:58)
        at java.lang.Thread.run(Thread.java:613)

Please enlighten me on what I can do to correct these problems. I am using this plugin analyze my results for my thesis.

Thanks!

The most likely problem is that they were compiled for a newer Java than
you have.  What is your Java version?

Hi!

Thank you so much for replying!

Java 1.5.0_16 -> I guess this is my version, I get this when I open ImageJ.

I downloaded the .java and the .class files for Kymograph from the following website: http://www.embl-heidelberg.de/eamnet/html/kymograph.html

Cheers,
Melissa

Could you upgrade Java to a version starting with 1.6?

Hmm.  That .class file conforms to version 49.0 (Java 1.5)...  No idea,
then, except trying with a newer Java...
