The RCrane interface. (a) RCrane assists the crystallographer in tracing phosphates and bases in the electron-density map. Here, the traced nucleotides are shown in green and orange, with the nucleotide that is currently being traced shown entirely in orange. The RCrane window on the right allows the user to select alternate phosphate and base locations. (b) After the backbone has been traced, RCrane automatically builds an all-atom model of the traced nucleotides. The user may then review the newly built structure and select alternate conformers where desired. |
