I am experiencing an error when i try to use Trackshceme ( i wanted to show plot features etc). The error is this:

Hi @Amna

It seems like a dependency error. I could not reproduce it on my side.
I do not know how it appeared. To move on, I suggest redownloading a fresh Fiji and trying with this one.


Hi tinevez,

Thanks for your reply…I did exactly with you said just redownloaded and it works now nicely :slight_smile:
