RCI Website RCI Help Wishart lab

RCI webserver predicts protein flexibility by calculating the Random Coil Index from backbone chemical shifts (Cα, CO, Cβ, N, Hα, NH) and estimating values of model-free order parameters as well as per-residue RMSF of NMR and MD ensembles from the Random Coil Index.

Basic usage
Select the format of the input file: BMRB NMR-STAR (Example) SHIFTY (Example)
Upload chemical shift file
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.


Advanced options
Random coil values: Schwarzinger (Default)  Wang  Wishart  Lukin 
Neighboring residue correction: Schwarzinger (Default)  Wang 
Exclude unassigned residues from analysis: Yes (Default)  No 
Should a correction of terminal end-effects be applied?: Yes (Default)  No  Exclude the first 3 and the last 3 aa 
Fill small gaps in distributions of secondary chemical shifts: Yes (Default)  No 
Correct referencing of chemical shifts: No (Default)  Yes
