Macro Error when using DiameterJ

Hi, I am new at using ImageJ. An hour ago, I used DiameterJ to analyse some samples and it worked. However, for some reason it has stopped working and this error keeps coming up.

I would be really thankful if someone could help. Thank you !


Hey @Silhouette

Could you share a Minimal Working Example? So share with us a representative section of code that results in the error when run and an example image (one that you upload or use one of the sample images that comes with Fiji). That will help us better help you.

Though perhaps @DiameterJ can assist off-the-bat?
