Update problem

Hi guys,

I realized after I didn't update KNIME/KNIP for quite some time that some nodes do not work anymore the way they did before. For example the Image Properties node is not able to read out the calibration data of an image. It still works with the old version, now I only get NaNs. The new Maximum Finder Node (which has replaced the Pick Image Peaks Node) always throws a java.lang.ArrayIndexOutOfBounds Exception upon execution. There are other problems as well. Just wanted to know whether you would recommend to avoid updating for some time.

Hi Christian,

are you on the nightly build? this is pretty unstable at the moment, as we are currently chaning several things concerning image metadata. this should be fixed end of the week.

sorry for the inconveniences!

Hi Christian

 

thanks for your reply. I sometimes use the nightly build just to check out your latest improvements. Anyway I switched back to the stable release now and it's fine.

Christian

Hi Christian,

actually this is super useful for us if you sometimes simply test your stuff against the nightly build, as we may simply overlook some bugs. So we appreciate your feedback!

Anyway, I fixed the MaximumFinder + several more in the last hours (Images weren't displayed correctly). Some Nodes (e.g. ImageReader/Calibration Data + ImageJ2 integration) we will fix in the end of the week, such that the nightly build gets usable again. Stable should work anyway for your productive workflows!

Again, thank you for your feedback. If you find any new bugs, please let us know :)

Christian!

 

Hi Christian,

we fixed several more problems concerning the nightly build, so I guess you could update again if you want to use the nightly build (and the amazing new icons :-))

Cheers and again thanks for reporting these issues,

Christian

Hi Christian,

the new icons are in deed amazing! Thanks for all your effort. I'm just afraid that there are still some bugs in the nightly build. This time the image reader node couldn't read a multi channel image stack correctly. It works fine with the old version. Somehow the channels and slices get mixed up. My guess would be that there is something wrong with the metadata handling.

Hi Christian,

could you send me an example image which can't be loaded? We actually changed alot in the Image Reader (or better a lot of changes in the libraries we use). I will try to figure out the problem then.

Thank you,

Christian

Hi Christian,

thanks to Mark Hinker from SCIFIO/BioFormats (providing the library to read/write images) we were able to fix the bug. With the current nightly build you should now be able to load your file.

Thank you again for your bug reports and sorry for the inconveniences

Christian

 

Okay, thanks. I'll try next week.
