[Chimera-users] Changing cryo-em density map x=voxel size in Chimera

Hello, I am using cryo-em density maps to create a deep learning model that detects C-alpha atoms. the model I trained uses maps with voxel size of 1x1x1 A. Experimental maps come in different voxel sizes. I found that I can change the voxel size using the option "model-spec". However, I looked everywhere in Chimera menu bar but could not find "model-spec". can you please show me where to find it. I am also open to any other suggestion to change voxel size.
