Frequently Asked Questions (FAQs)

Your may find answer to other questions at the Service System Discussion Board.


1, Why did I fail receive the password for I-TASSER Server after my registration?

2. Why does my password not work for I-TASSER Server?

3. Why does my password not work for I-TASSER Suite, I-TASSER Forum, or QUARK server?

4. How can I predict the structure of a protein with >1,500 residues?

5. How can I run I-TASSER suite on Mac, Windows or 32-bit Linux?

6. Why my SAXSTER prediction did not return any result?

7. How can I use I-TASSER models to study the effect of mutations on the overall topology?

8. How do I report bugs for web servers and bioinformatics tools in Yang Zhang lab?

9. What are the 'top 10 templates used by I-TASSER' in the Result page?

10. What is the 'top 5 models predicted by I-TASSER' in the Result page?

11. What are 'Proteins structurally close to the target in the PDB' in the Result page?
