AccPbFRET error with registering an image

[John Alexander-7]

Hello group ...

I've begun to use the AccPbFRET plugin to analyze some FRET
images, but when I get to Step 2: register donor images I get
the error java.lang.NoClassDefFoundError: ShiftDialog
Can anyone help me figure out what that means - how to
rectify it - and (perhaps most importantly) if it is
affecting the use of this plugin!

Thanks!

Hi John,

it means that the ShiftDialog.class is missing from the ImageJ\plugins
directory. You may accidentally deleted it, or the class file has not been
created for some reasons. You should try to recompile the plugin, and check if
ShiftDialog.class exists. And it's also a good idea to download the newest
version of the plugin:
