Extraction protocol |
Library was transformed in cells with or without Cas13a and backdiluted 1:100 in LB with antibiotics to reach OD 0.06 and let grow for 12 hours shaking at 37°C. Finally, the library was midi-prepped with ZymoPure II Plasmid Midiprep Kit (Zymo Research, D4200). The library prep was amplified with Kapa Hifi polymerase (Kapa Biosystems- Roche, 7958889001) according to the provider protocol. The reactions were purified using Ampure beads and further amplified to add the appropriate indexes and illumina adaptors. The resulting product was again purified with Ampure beads and run on a gel to verify the presence of the correct amplicon. The samples were sent for Sanger sequencing to make sure to get the expected sequence and then their quality was checked at the Bioanalyzer. Finally, they were sent for sequencing at the Next Seq sequencer (Illumina) with a 150 bp paired-ends kit (130 million reads) to get 1000x coverage. To increase the library diversity, 20% of phiX phage was spiked-in.

Data processing |
Library strategy: DNA-seq Paired-end reads were merged using BBMerge (version 38.69) with parameters “qtrim2=t, ecco, trimq=20, -Xmx1g, mix=f” reads with perfect matches were mapped to reference genome with In-house python script Genome_build: NC_000913.3 Supplementary_files_format_and_content: CSV, raw counts of gRNAs in each sample
