About Side-Chain RCI:

Side-chain RCI webserver predicts protein side-chain mobility by calculating the Side-Chain Random Coil Index from side-chain chemical shifts and predicting per-residue RMSD of NMR and MD ensembles as well as fractional accessible surface area of protein residues from the Random Coil Index.

You can also download a Python stand-alone side-chain RCI program for Linux here. Main-chain RCI web server can be accessed here.

Basic usage

Select the format of input file: BMRB NMR-STAR 2.1 (Example) NEF (Example)

Upload file with chemical shifts here:



Paste chemical shifts into the text box below:
IMPORTANT: If a file is selected for upload above, it will be used and content of the text box below will be ignored.

Input name:   
Name is optional and used only when you paste shifts. Please use letters and numbers only, no spaces.
Input name will become a part of output filename. If you do not name your input, a random number will be used.
