I have been using Qupath for some time now to generate H-scores for a number of stains.
I am encountering the following problem: When I try to open a previously saved file (project.qpproj), I get the following message: “Qupath has encountered a problem, sorry If you can replicate it, please notify a developer. Java.lang.NullPointerException”. I get this message with certain files but not with all of my saved files. These files are saved under a common drive. I have also tried to copy the file and open it from my desktop, but this hasn’t helped either.
I would appreciate any input on the above issue!
