Hi - I am trying to run the plugin "Extract SIFT Correspondence" in
ImageJ and I get an error: “Plugin or class not found: SIFT_ExtractPointPoi”. I copied the mpicbg_.jar file from the Fiji plugins directory to the ImageJ plugins directory and the SIFT plugin appears in the Plugins menu as expected. Last Friday I posted a message about problems I'm having writing plugins in Eclipse. I haven't been able to make progress with that (advice still appreciated) but I wanted to make it clear that for this problem I am running ImageJ as an Ubuntu application. I expect I'm doing something really stupid but after two days I haven't been able to figure it out. All the best, Ned -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Most likely you are missing mpicbg.jar (which lives in Fiji's jars/ directory, but for plain ImageJ 1.x it has to live in plugins/, too).

Hi Johannes,
Thanks so much. That did the trick and of course it seems to have solved the problem I was having building my plugin using Eclipse. I had no idea there were two sets of jar files for some plugins. I have a lot to learn...

Hi Ned,
mpicbg.jar in Fiji's jars folder is supposed to contain all library parts, mpicbg_.jar in plugins contains the ImageJ/Fiji plugins that make use of it. For actually writing code re-using the libraries, mpicbg.jar is the more important file (it also generates more informative javadocs). Instead of running the plugins from a plugin (which means text-based blind guessing in most cases) I would inspect the actual plugin's code and see how it actually does it with the library---that will get you further and also generate the right errors at compile or code time :). Hope you're having fun. Best, Stephan On Mon, 2012-07-02 at 15:28 -0400, Ned Horning wrote: > Hi Johannes, > > Thanks so much.

Hi Stephan,
Thanks for the explanation and clarification. For now it's a lot easier using IJ.run but my intent is to learn to use the SIFT library directly. It's still a bit overwhelming but it's slowly beginning to make sense.
