[ome-users] Bug report: Cannot open jp2 file created by StereoInvestigator

[Sebastien Besson (Staff)]

Thanks Kouichi,

For R2017a, the results are definitely matching the expectations.

For R2017b, getting a no found class result is surprising and does not match the previous
thread [1].

Was the whereisjavaclassloadingfrom call executed right after MATLAB startup? If so, could
you execute it again after running the bfopen command? The latter should automatically add
the Bio-Formats JAR to the dynamic classpath.

Best,
Sebastien

Dear David,

Below are the results I've got. R2017b returned an error, whereas R2017a ran properly.

path (R2017b) output includes the following (just to make sure).

D:\Dropbox\Private_Dropbox\matlab_toolbox\bfmatlab


Best regards,
