I loaded a 2D sequence volume and created a transform to apply to the sequence setting spacing for X, Y, and Z dimensions. Z was set to 0.2mm from a default of 1.0mm. However, centering the axial red slice after applying the transform appears to still center to the position of the original bounds in Z which was a default 1.0mm. However after dragging the axial red slider to the ends and back it then fixes itself in regards to having the center of the slider mean the center of the bounds. Is there something else I can call to trigger this update? Or is there something else incorrect in this method of applying spacing?

After clicking center button for axial red slice:

Here is an [example scene](https://sonovolinc-my.sharepoint.com/:u:/g/personal/jbutler_sonovol_com/ESKaVQLYHGNLnHnhb97DB_gBg_d2VMPLobpkIqM10SgL6Q?e=Lcn6kx). When you turn on slice intersection and then click the center button for the red axial slice view, it is not centering to volume bounds.

I was able to reproduce the problem and I’m working on it.

I’ve [fixed the issue](https://github.com/Slicer/Slicer/commits/master), tomorrow’s Preview Release should work well.

Thanks! I tried my scene again and the fix appears to work well.
