Before revision:  On 15 crystallographic datasetsfor ribozymes, riboswitches, and other RNA domains, ERRASER/PHENIX corrects the majority of identifiable sugar pucker errors, steric clashes , suspicious backbone rotamers, and incorrect bond lengths/angles, while, on average, improving Rfree correlation to set-aside diffraction data by 0.010.
After 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 identifiable sugar pucker errors, steric clashes , suspicious backbone rotamers, and incorrect bond lengths/angles, while, on average, improving Rfree correlation to set-aside diffraction data by 0.010.
