Hi everyone,

I have installed image J Fiji on my new computer and also Ratio Plus plugin. However, when I ran the Ratio Plus, I encounter this error message. Could someone help with some advice etc to fix this?



Thanks

Hi Sindy,

>(Fiji Is Just) ImageJ 2.0.0-rc-30/1.49s;

First I would suggest running "Help > Update...".

Also it would be helpful to know if you have other update sites enabled or
plugins manually installed. You can get this information easily from the
"Useful information about your system" window in the "Help > Report a Bug"
command.

>java.lang.ClassFormatError: Truncated class file

How did you install the plugin? I just downloaded a fresh copy of the
.class file from http://rsb.info.nih.gov/ij/plugins/ratio-plus.html and had
no problems running it with both Java 6 and Java 8; so if you did something
else it's worth trying to re-install.

Hi Mark

Many thanks .. Tried the Help.Update etc. Finally found the problem... I had installed ImageJ Fiji in a "Protected" Program folder and have shifted it to the "General" folder. Everything is working ok now... phew!
