Hi Hiroshi, It's too bad that you can't use a newer version since the handling of files/folders with non-ASCII characters in their names is much improved compared with old versions. Also, I'm surprised that surfacing works in an old version but not a newer version. For the most part surfacing is more robust in newer versions. Also, we expect to have a new surface library available in a release Real Soon Now. My advice is to make sure that your file name has only ASCII characters in it, the folder it's in has only ASCII characters, as well as the folder above that, etc. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Sep 17, 2009, at 2:34 PM, Hiroshi Nikaido wrote:

Hello, I sometimes have to use older versions of Chimera (1.2350 or 1.2422) because the more recent versions refuse to calculate surfaces for my protein. They used to work fine in my old computer running windows xp, but with my new computer (still running xp) an attempt to try any pdb files on my hard disk produces an error message (TypeError: argument 1 should be a str.). How could this problem be fixed? Your help will be greatly appreciated.
