Thanks! This is a good solution. But I wonder if there's an interactive way just like the eraser, but doing the opposite thing. It might help on difficult cases when you want a real time feedback what you are erasing and keeping just in Chimera without external command. Kai

Dear Chimera users, Dose anyone know how to do inverse volume-erasing? Normally we use the eraser to erase density we don't want to keep. However, what shall I do if I want to keep the density within the eraser while getting rid of other parts? Many thanks Kai _______________________________________________ Chimera-users mailing list Chimera-users@cgl.ucsf.edu <javascript:;> http://plato.cgl.ucsf.edu/mailman/listinfo/chimera-users
