Dear ChimeraX team,

I’ve created a .deffatr file to color residues in a chain by a custom attribute (attached). It seems that ChimeraX opens it correctly: 

open "/Users/ortizmateujuan/MEGA/MEGAsync/MemProtLab_UV/PROYECTOS LAB/Proyecto F1L VaccV/Alphafold/scanF1L.defattr"
Summary of feedback from opening /Users/ortizmateujuan/MEGA/MEGAsync/MemProtLab_UV/PROYECTOS LAB/Proyecto F1L VaccV/Alphafold/scanF1L.defattr
noteAssigned attribute 'ld50' to 17 residues using match mode: 1-to-1

However, when I go to Render/Select by attribute, it does not appear on the list, and when I try with commands it says: 

color byattribute ld50 palette ^rdylbu
No known/registered numeric attribute ld50

Could you help me with this? Thank you very much. 

PS. I want to unsubscribe to this mailing list. I have tried emailing chimerax-users-leave@cgl.ucsf.edu many times but I keep receiving these emails. Could you do it for me please? Thanks again.
