DCI Server

About DCI

DCI server is used for protein complex structure assessment. DCI-score is a new evaluation strategy for protein complex which only bases on distance map and CI (contact-interface) map.

It can give a global assessment for complex structure, DCI-scores ranges from 0 to 1, value is higher when two structures are more similar.

Submitting Jobs

This server requires two pdb files corresponding to ground truth and predicted model
Note that two files are not inverted when input
In order to make each chain of two structures correspond correctly, predicted model chain order based on ground truth should be given at "Model Chain Order"

Job Output

You will get a txt file with evaluation results containing:

Basic structure information (names, lengths)
Three constituent subunits: inter-Fnat, intra-Fnat and difference value
Two calculation strategies: DCI(penalty) and DCI(no penalty)

Download Example

The examples contain two pdb files to help you understand the correct format and chain ordering.

7AC9.pdb - Ground truth file
7AC9_finetune.pdb - Predicted model file

Ground truth chain order: "H L I"
Corresponding predicted model chains: "D B C"
Input file order: "B C D"
Required Model Chain Order input: "DBC"
