Dear Rafael, You just need to get a newer ChimeraX (i.e. download the daily build), which will include the latest version of the atomic bundle. Some bundles are only in the download and not available separately. I hope this helps, Elaine ----- Elaine C.

Dear ChimeraX staff,

I cannot restore a ChimeraX session and ChimeraX suggests to update atomic bundle to version 1.31 or newer (have 1.13.2). When I go to all bundles (https://cxtoolshed.rbvi.ucsf.edu/apps/all) I cannot find the way to update it properly. Could you help me to fix the error?
