Is multiple sequence alignment absolutely required?
A multiple sequence alignment is required when the prediction needs a profile. When you use [S], [AS], [ASD], or [A2SD], in other words the methods without P, an alignment is not needed.
Can't the server perform multiple sequence alignment?
Actually yes. Follow the link here. But our server machine is not powerful enough to perform homology search and a huge multiple sequence alignment, sorry. We are think about updating the server in the future.
How does the program define surface residues?
Accessibility of every residue is calculated based on the input PDB file, and all the residue with accessibility more than 0.08 is considered as surface residues.
Why is ID necessary?
The prediction program is not sophisticated enough to tell which of the sequence in the multiple sequence alignment is identical to the amino acid sequence in PDB. We will update the program shortly.
Is there a text output for the score?
At the moment no. Please download the prediction result file in PDB format and select a value shown in the column of temperature factor of ATOM row. By selecting the values of CA only, one can obtain the score.
Why is the prediction slow?
A number of reasons. Slow network traffic, slow programs, slow server. Just be patient, svp.
A non-RNA binding protein is predicted to have RNA interface residues. Why?
The question that the prediction method is trying to answer is "Here is a RNA-binding protein. Where is the RNA binding surface?" Therefore, if one perform prediction on non-RNA-binding proteins, the usage is out of the range of the question that we tried to answer by the method. The question such as "Here is a protein. Does this protein bind to RNA?" is, however, an important question and we would try to have a method to answer this type of question in the future. Besides, there already are a couple of methods to answer this type of question such as BIDD.
What is the detail of the prediction method?
Read help page. Further detail of the method is now under review at Nucleic Acids Research Editorial Board.
How can I access the tool from the unix command line?
Here is a C++ program to use KYG method from a unix command line. With curl, a unix command, you can use this website from your program.
curl -F "method_type=8" -F pdb_file=@1ETF_P.pdb http://cib.cf.ocha.ac.jp/KYG/KYG.php | ./parseKYG.exe
