** | ** remove all restraints: lines begining with SIMU, DELU, ISOR, BUMP, DFIX, DANG, CHIV, FLAT (from "Mini-protein refinement tutorial"). (Editor's) Note a): NCSY then should also be removed, right? b) all of this is only useful for high-resolution work (let's say 1.4 A). At low to medium resolution my question would rather be: what are the s.u. on distances between these atoms, given that these atoms are covalently bound to other atoms, and are thus restrained? | ||
** BOND, RTAB, HTAB and MPLA instructions may be needed to define the dependent parameters for which esds are required (from "FAQs: Macromolecules") | ** BOND, RTAB, HTAB and MPLA instructions may be needed to define the dependent parameters for which esds are required (from "FAQs: Macromolecules"). As an example, BIND FE_5001 NE2_123 together with BOND FE_5001 NE2_123 would enter the distance between FE_5001 and NE2_123 into the connectivity table, and would print out the distance and its s.u. in the .lst file. | ||
