[Chimera-users] Concerns regarding secondary structure

[rquiroga at immf.uncor.edu]

Greetings,

I have some concerns with Chimera's secondary structure detection/depiction.

I am using Modeller to predict some 3D structures.

I open my predicted structure in pdb file in Chimera along with the original
structure I based my prediction on, and find that my predicted structure lacks
two beta sheets that the model protein has, though the AA that compose the
B-sheet are identical for the two proteins when I compare sequences with
Matchmaker.

I tried opening my predicted structure in MolMol and it detects the B-sheet,
though I hugely prefer Chimera, so if you could solve this problem for me I
would be very greatful.

Thanks in advance, and regards
