Did you know... Align Two proteins after structure alignment align performs a sequence alignment followed by a structural superposition, and then carries out zero or more cycles of refinement in order to reject structural outliers found during the fit. align does a good job on proteins with decent sequence similarity (identity >30%). For comparing proteins with lower sequence identity, the super and cealign commands perform better. Usage align mobile, target [, cutoff [, cycles [, gap [, extend [, max_gap [, object [, matrix [, mobile_state [, target_state [, quiet [, max_skip [, transform [, reset ]]]]]]]]]]]]] Arguments mobile = string: atom selection of mobile object target = string: atom selection of target object cutoff = float: outlier rejection cutoff in RMS {default: 2.0} cycles = int: maximum number of outlier rejection cycles {default: 5} gap, extend, max_gap: sequence alignment parameters object = ..→
