Hello:

I'm using ImageJ 1.43t (java 1.6.0_20) with the Bio-Formats plugin to import different file formats. It has been working great for Olympus confocal microscope files with oib extensions.

Today I noticed a problem. I had saved some files today and could not open them, but previous files (2 days ago) open fine. I can't find a difference in the files using the Nikon fluoview software, which works fine for today's and earlier files.

When I try to open today's oib files, the Bioformats import window comes up and after clicking on my choices it disappears and I get the following errors:

java.lang.NullPointerException

Again, the key point is that this does not occur with oib files saved 2 days ago which points away from an ImageJ problem. I should also mention that this problem occurs either under Windows or Linux.

Any suggestion would be appreciated.

Pedro
