Hi Nebojša, When you open a volume file ChimeraX reports the voxel size, for example 2.7 Angstroms in the following example > open 1080 from emdb Opened emdb 1080 as #1, grid size 100,100,100, pixel 2.7, shown at level 1.68, step 1, values float32 Then if you wanted to change it use volume #1 voxelSize 2.5 or you can use menu Tools / Volume Data / Map Coordinates and change the voxel size entry in the panel that appears.

Hello,
I have two maps. One from cryosparc @ 1.06 A/pix and another EM-gan sharpened map @ 1.0 A/pix. They are different in size upon visual inspection in chimeraX so I tried relion_image_handler --i cryosparc.mrc --angpix 1.0 --rescale_angpix 1.06 --o cryosparc-rescaled.mrc however, the resulting map is still smaller than the original input. I also tried to rescale in this way to several different angpix values but maps are still not the same.
Is there any command in chimeraX or chimera to play with pix sizes to find the right one?
Thank You and regards,
