Looking at a sample under the Virtual Microscope [Bean Weevil]

The Virtual Microscope is a NASA-funded project that provides simulated scientific instrumentation for students and researchers worldwide as part of NASA's Virtual Laboratory initiative. This site serves as home base for the Imaging Technology Group's contributions to that project—namely virtual microscopes and the multi-dimensional, high-resolution image datasets they view. Currently we provide 90 samples totaling over 62 gigapixels of image data. The Virtual Microscope, which is available for free download supports functionality from electron, light, and scanning probe microscopes, datasets for these instruments, training materials to learn more about microscopy, and other related tools. The project is open source and the code is available on Sourceforge...

Specimen Download Bug

The latest version of Virtual Microscope (6.2.2) has an incompatibility with some recent operating systems that is resulting in a few users not seeing any available specimens to download in their 'Get More Specimens' section. New installs of the software will see the three included specimens in the top section, but no buttons to grab more in the lower section.
Working Around The Bug

If you are having this problem, there is a manual workaround. You will need to download the specimen files by hand and manually copy them to your Virtual Microscope specimens folder. Step-by-step:

  • Visit Index of /data/jars.
  • Right click and 'Save As...' any of the .jar files that interest you (each one is a full specimen file).
  • Save them to a folder on your computer.
  • Find your Virtual Microscope 'specimens' folder. For Windows users, this will be in C:\Program Files\Virtual Lab\specimens or something similar to that.
  • Copy all of the .jar files you downloaded into the specimens folder.
  • Restart Virtual Microscope.
  • You should now see the new specimens in your 'My Specimens' area
