Dear All, I am trying to color code a structure according to HetNOE. When I load the attribute list using "Define Attribute" via the "Structure Analysis" menu the program does not automatically open the "Render by Attribute" menu. If I click and open the "Render by Attribute" menu, the program does not show my file in the attributes list for residues. Does anyone have an idea of why this happen? I have pasted my attribute's list below. Thank you, Roberto attribute: teste recipient: residues :377.000000 0.842818 :378.000000 1.273292 :379.000000 0.763398 :384.000000 0.852818 :387.000000 0.999787 :388.000000 0.572572 :389.000000 1.016109 :393.000000 0.950908 :397.000000 0.761818 :399.000000 0.712411 :402.000000 0.388721 :403.000000 0.495060 :408.000000 0.460664 :411.000000 0.973597 :412.000000 1.036187
