Guide RNA design for CRISPRi in bacteria
Input the sequence of a target gene and this script will output candidate guide RNAs for the S. pyogenes dCas9 with predicted on-target activity and an analysis of off-targets. Predictions are made based on a model of dCas9's ability to block the RNA polymerase of E. coli (Calvo-Villamañán et al., 2020) .Start
