Hi Sumitro, The shortest answer is no, there is no way (barring some Python shenanigans). You could clear SS assignments afterward with: setattr r isHelix false # setattr r isStrand false # Can you describe why you want to turn off the SS computation? We might make it optional somehow if it was of general use. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Mar 14, 2010, at 6:54 AM, Sumitro Harjanto wrote:
Hi,
Is there any way to turn off automatic secondary structure assignment upon opening a pdb file that does not contain secondary assignments?
Cheers, Sumitro
