[chimerax-users] Smaller map when volume eraser

Hi all * I know that when performing volume zone, we can set minimal Boundaries true, so we get a smaller map compared to the original. * Volume eraser gives zeroes, but as far as I understand, the size of the map is kept. My maps are huge and my laptop is as it is. I am wondering if there is any option of, instead of getting zeroes when erasing, getting rid of this values and get a new, and smaller map, to work with lighter maps. I use  the volume zone, and reduce boundaries, but sometimes is more convenient the erase tool... Regards and thanks! Marta
