Hello all. As we know, by using 'subvolume' function we can extract volume data in cuboid form which is controlled by the limits . I want to ask that, IS there any process with we can extract subvolumes with 'subvolumes' function in different shapes such as - cylinder,sphere,conical etc. ? Thank you :)

Well yes and no. As you probably know, an image must be rectangular. However you can mask the volume by some oddball shape so that everything else is zero, and then you can extract the bounding box. So it will be rectangular but the shape will be surrounded/filled with zeros from the shape out to the boundaries of the image.

Them you should get some background in the logical operations such as AND and OR. Try this link: https://www.google.com/?gws_rd=ssl#q=logical+and+matlab
