Hi Natalia - try changing the file format you are saving as to 'ChimeraX Session' (.cxs) - this will capture the colours, how the molecules are rotated and shown and lots more. Hope that helps !

Is there a different way to be able to keep a section highlighted/different color when I save it as a pdb file? Thanks! The University of Dundee is a registered Scottish Charity, No: SC015096
