Hello everyone. I was trying to refine my model anisotropically. I selected element NA or (chain A and not element H). I looked at the output pdb shows that hydrogens were being refined anisou as well as the protein. I believe its because technically they are also in chain A, but shouldnt the default be never refine H's anisotropically, especially at 1.5A ?. -- Yuri Pompeu
