I have recently used the I-TASSER server to successfully generate a 3D model for a peptide loop on which I am working (ID: S66741). When viewing the output online via the JMol appelet on the I-TASSER website, a combination of alpha-helical as well as beta-sheet regions are visible, reflecting the prediced secondary structure patterning listed. However, upon saving the various model files and opening them in PyMol, the alpha-helical regions remain visible, but the beta-sheet regions do not appear (when displayed in "cartoon" format). Should the information coding for the beta-sheet region still be preserved in the saved model file, or must a certain threshold level of confidence be met before this information is kept in the saved model files? Any help would be greatly appreciated. Thank you in advance.
