Before revision:  On 24 RNA crystallographic datasets, including a 30S ribosomal subunit and an unreleased IRES domain of hepatitis C virus, the protocol corrects the majority of steric clashes and anomalous backbone and bond geometries, as assessed by MolProbity.
After revision:  On 24 data sets, ERRASER automatically corrects the majority of steric clashes and anomalous backbone and bond geometries, as assessed by MolProbity.
