Hello all, First please accept my apologies for to open a topic which is discussed already, but I couldn't get it working. I would like to morph a volume and colour its subregions. I made the following script ( adopting old messages in this forum ) open 1.mrc open 2.mrc open start_full.pdb open end_full.pdb vol #0,1 level .025 # Create a marker for coloring measure center #2 mark true radius 20 color red ~display #4 # Create morph vop morph #0,1 frames 0 model #5 # Color near marker scolor #5 zone #4 range 50 #Play morph vop morph #0,1 model #5 frames 200 interpolateColors false In the above script everything works, but color stays at place. Unfortunately for my morphing the marker has to move along with the morph. But I dont know how to do that. Any help in this regard would be very helpful. best regards Rajan
