Chris,

As usual, really appreciate the troubleshooting. I was able to turn the MRIcroGL animations to png files, (ktime= 40, ksteps= 180), and tried using ImageMagick to convert the png files into a gif.

I used this 

"convert -delay 10 -loop 0 MNIslice*.png MNIanimated.gif"
then
"convert -dispose previous MNIanimated.gif MNIanimated2.gif"

However, every couple of frames, the gif seems to be including an older frame relative to it's current frame, leading to a weird jump in the animation.

Here's the animation below (both MNIanimated.gif and MNIanimated2.gif look the same):

I know it's not really a MRIcroGL issue, but was hoping you can help

Thanks!
Andrew
