Weird slicing where two hemisphere appear and one hides the other #18

Will add screenshot later.

Example patients: EC71, 181, 208,210, 166

In the past, these were fixed by hardcoding fixes. It would be good to find a fix in the software so that it does not happen.

EC166 has the glitch with #5, but not with the previous version. Will investigate why.

Here is a screenshot with #5:

Here is the same patient with the original OPSCEA:

It seems #5 makes it so that the both hemispheres are plotted when the angle of the slice is close to 90˚. On the other hand, the older version of the software may plot the wrong hemisphere and rotate the brain the wrong way. These issues only seem to appear when a slice plane is close to being parallel to the longitudinal fissure.

The old version of the software seem to also cause the issue where both hemispheres are plotted sometimes, like in this comment. Example patients of this: EC181, 210

5 fixes that it seems

Example patients that have the two hemispheres with #5 :EC208, 71, 166, 86
