Summary0001875: strange behavior of the volume module
Description
  1. load dwi volume in nrrd format (Users/rkikinis/Downloads/2011-12-14-AMIGO-Neuro/DWI.nhdr)
  2. go into the volume module
  3. try to open the help tab under help and acknowledgements

Any action results in a beachball display for about 20-30 seconds, effectively making Slicer unusable.

As an aside: help points to the help for the diffusion editor, but that editor does not appear to be available.

TagsNo tags attached.

That delay is almost certainly the histogram calculation - which is a shame because the histogram isn't visible by default. It would be better to do a lazy evaluation of it, possibly in a thread.

upon further experimentation, I found out that the beachball occurs after I make the histogram visible. This should be either removed or made more responsive.

The slow down is the reason why the histogram is hidden by default. The slow computation only happens when the histogram is visible.

The histogram view is implemented with Qt. It needs to be done with VTK charts.

I Just tested this with the SampleData nrrd DWI file, it took a long time to download but going into the Volumes module, the module opened quickly and the histogram showed quickly as well.
Ron are you still seeing this problem?

Confirmed that the crash does not happen any longer. However, the reference in the help message about the diffusion editor still needs taken care of.
