Hi,

I am using AFNI to make some very pretty pictures of MEG results. We have timecourses at each voxel in the brain, computed with a beamformer.
I discovered that by setting the environment variable:
AFNI_SLAVE_THRTIME = YES
and setting \"time lock\" in \"Define Datamode,\" one can make some cool movies by sliding through time windows, showing how activation patterns (i.e. voxels exceeding an arbitrary threshold) move through the brain with high temporal resolution.

One thing that would make the movies even prettier would be to do this in the volume renderer, so I can make 3D movies and really impress people at talks without having to rely on good science. Unfortunately, it seems that the volume renderer does not respond to the environment variable, so as you slide through time in the graph window, the overlay dataset is updated, but the threshold stays on the same subbrick (the same behavior as the regular afni window without the environment variable set).

Perhaps some wonderful programmer could take the piece of code that updates the threshold subbrick in the regular afni viewer and apply it to the volume renderer as well? There could be donuts involved...
