Re: [micro-manager-general] SPOT insight color camera

[MEYENHOFER F. <fel...@un...>]

For me it was similar. When adding the SPOT Camera as "Camera" in the first attempt the error window disappeared. (adding as "camera" did not work and once an error window appeared, it would re-appear after changing the its name).
I also tried to install the MM to "Program Files (x86)" but that turned out to be a waste of time since the path to "Program Files" seems to be hardcoded (as I concluded from the directory where it looks for the confirmation files).

However I checked the logs and found the following:
The camera (once added with "Camera" in the first attempt) seems to initialize fine.
A couple of seconds later it throws:

java.lang.NullPointerException in Thread[AWT-EventQueue-0,6,main]
  at org.micromanager.graph.SingleChannelHistogram.calcAndDisplayHistAndStats(SingleChannelHistogram.java:472)



Then after going to "live view" it repeatedly throws:

The complete log you can find under the following link:

So it really seams that MM is not able to process the data received from the Camera. Does this lead back to a coding or a configuration error???
