Hi Christopher, You just need to get a newer version of ChimeraX. According to the change log <https://www.rbvi.ucsf.edu/trac/ChimeraX/wiki/ChangeLog> ...this feature was added in December 2021 subsequent to the 1.3 release. Thus you need to get the current daily build from the download page: <https://www.rbvi.ucsf.edu/chimerax/download.html#daily> Also make sure that you include the plus sign (+) immediately before the value in the command if you want to change radii relative to current sizes. If you use the help included with your download (e.g. command: help size) it would be synchronized with what you have. However, if you use the help pages at our website, they reflect the latest changes, which may be only in the latest daily build. I hope this helps, Elaine ----- Elaine C.

Hi, I am trying to adjust the size of multiple individual residues in a molecule. I am attempting this with the "size [Target] atomRadius +[value]" command. When I run this, it doesn't perform a relative shift of each atom size in the residue but appears to set all atoms in the residue to an absolute size of the value. The documentation states that including the plus sign should make it a relative change. I am using ChimeraX 1.2.5. I appreciate your help figuring this out, Christopher Handelmann
