I am encountering the problem while generating the constraints form N-15 edit AND C-13 EDIT NOESY files that very few constraints 200 out of 2400 peaks . Calibration is OK . chemical shift file is good agreement with secondary structure of know crystal structure . Completeness of assignment: Completeness of all atom assignment is 80.74 %. Completeness of proton atom assignment is 82.50 %. Completeness of heavy atom assignment is 74.56 %. Completeness of all atom assignment is 74.58 %. Completeness of proton atom assignment is 82.50 %. Completeness of heavy atom assignment is 65.94 %.
what can be the another possible problems ?
Anyone could you please make some helpful comments
