Java error with CASA plugin for ImageJ

[Joanito]

Hi everybody,

this is my first post in this forum so I apologize in advance if this sounds like a dumb question.

I'm trying to run the CASA (Computer assisted semen analizer) plugin for image J. The plugin opens fine and asks me for the various parameters that should be entered for the analysis (so the plugin seems to work fine by doing compile and run), but then when I run it I get the following message:

ImageJ 1.48v; Java 1.6.0_20 [32-bit]; Windows 7 6.1; 254MB of 1638MB (15%)
 
java.lang.ArrayIndexOutOfBoundsException: -1
        at CASA_.track(CASA_.java:532)
        at CASA_.run(CASA_.java:161)

        at ij.plugin.PlugInExecuter.run(Compiler.java:313)
        at java.lang.Thread.run(Thread.java:619)

The input for the plugin is and image sequence or an .avi video. I've tried the sequence as tiff or as jpg and tried also with the .avi, but I always get the same error.

What might be the problem?

Thanks in advance for your help!
