Dear all, I've got a problem when rerunning the same job of my project in the new laptop. I've found that it's because of the NCS restraint groups set-up In the old computer I set two NCS restraints groups as: First group: Reference group: chain A and sidechain and resid 3:216 and not (resid 63 or resid 66 or resid 81 or resid 93 or resid 133 or resid 135 or resid 181 or resid 184 or resid 193 or resid 194 or resid 212) Second group: Reference group: chain A and backbone and resid 3:217 and not (resid 63 or resid 133 or resid 135 or resid 184) And the refine_phenix run well in the old computer, but the new laptop with the error in the end of this letter. I've found that if I delete the backbone in the second group, it runs again. So I wonder that how I could refine NCS restraint of backbone now? Thank you in advance.
