完整度0.97,0.95還低嗎? The Data/Parameter ratio for this structure is 4.86, which is below the generous RSC cut-off value of 5. 這個(gè)數(shù)據(jù)從哪里得來? The number of restraints is reported as 647. I am very curious as to why so many are suddenly needed,這個(gè)數(shù)據(jù)從哪里來? The number of restraints is reported as 6, 這個(gè)數(shù)據(jù)來自何處?這也太專業(yè)了! 望高人指點(diǎn)。 下面是審稿意見的原件。 The authors have applied squeeze to this model, which has improved the R-factors and the structure generally. The values for the density, F and mu need to be adjusted to take account of the new chemical formula. The presence of the solvent water should really be corroborated by using another (non-crystallographic) method such as TGA or DSC. Coverage is reported as 25.10, which satisfies the requirements, but the the completeness is reported as 0.973, which is too low. The Data/Parameter ratio for this structure is 4.86, which is below the generous RSC cut-off value of 5. The number of restraints is reported as 647. I am very curious as to why so many are suddenly needed, when the previously submitted structure has none, and the model itself has not changed much? I would suggest that most of these restraints are unnecessary. Structure scw762s (CCDC 1041245): C30 H38 Cl4 Cu N6 O5 Thank you for recollecting the data for this structure. Coverage is reported as 25.00, which satisfies the requirements, but the the completeness is reported as 0.952, which is too low. Please give a reason for this, and bear this in mind for future collections. The number of restraints is reported as 6, but no details about these restraints were given in the _refine_special_details section of the cif file. This information can also be provided by making use of the restraint CIF dictionary items. This is not a RSC requirement, however please consider adding all information about restraints and constraints to the cif - this makes the file much more useful for future readers. C11, C12 and C14 are probably disordered, by looking the shape of the thermal ellipsoids. Please comment if any attempt was made to model this. |

說句話,不是人家專業(yè),而是你不專業(yè),幾點(diǎn)意見 1.完成率都是收到0.985的,0.97和0.95確實(shí)達(dá)不到標(biāo) 2.Data/Parameter 在cif里面可以自己算的, 3.限制性精修數(shù)目 restraints 在cif里面都有 4. 647個(gè)restraints確實(shí)是太多,建議你重修檢查加入的命令,肯定有些是unnecessary, 5. squeeze命令用了之后確實(shí)需要其他手段比如DSC、TG或者元素分析來確定你squeeze掉的到地是什么,加進(jìn)去重新算化學(xué)式 6.restraints中各個(gè)命令的使用目的,如審稿意見,需要在cif里面_refine_special_details 說明, 7.C11, C12 and C14 無序,好好處理一下 綜上所述建議你找個(gè)懂得人好好處理一下,祝好運(yùn) |
