Hi, so the question ist pretty much the title. I have a 3d volume loaded as raw data [256, 256, 256] = size(A). It contains only values of zero's and ones, where the 1's represent the structure and 0's the "air". I want to visualize the structure in matlab and then run an algorithm on it and put an overlay on it, let's say in the color red. So to be more precise:

1. How do i visualize the 3d volume. 0's transparent, 1's semitransparent?
2. Plot a line in the 3 d vis as an overlay?

I already read the mathworks tutorials and they didn't help. I tried using the set command, but it fails completly saying for every property i try "invalid root property". I hope someone can help.
