Imspector MSR: NumberFormatException when parsing timepoints #4139
Comments
This issue has been mentioned on Image.sc Forum. There might be relevant details there: |
I was able to re-produce the issue with the test image in Fiji. In Eclipse, I modified the code in https://github.com/ome/bioformats/blob/develop/components/formats-gpl/src/loci/formats/in/ImspectorReader.java The changes are below. The variable valueType was 9 during the error so I moved the case 9 statement down to the section that does readInt(). Line 316:
With the code change the error did go away and I got the Image below. Not sure if this image is correct Not sure if this is the right fix. Not sure what else this might break. Just thought I'd share this info. :) |
Referring to the original code, "Time Time Resolution" is the value of variable key when the exception occurs at line 429. The exception occurs because it is doing a readInt() but was parsed using readFloat() at line 330. Note the string "2.8E-43" in the stack trace exception. In Eclipse I made some changes to only have the logic changed for when variable valueType is 9 and key is “Time Time Resolution”. Starting back from the original version of ImpsectorReader.java, I just added an if statement to do readInt() when key is “Time Time Resolution” for case 9.
The results are the same as before. No exception |
Thanks @scuniff for the testing, if you are happy that solution is working then do you want to open it as a PR and we can test it against our repository of sample files? |
