- Pre-processing options: `–trim_sequences –trimmomatic_command trimmomatic –trimmomatic_options_string ’ILLUMINACLIP:TruSeq3-PE-2.fa:2:30:10 MINLEN:100’` to get rid of low-quality positions (score < 30) and to remove Illumina adapters, keeping only trimmed sequences longer than 100bp
- Sequences were mapped to the input amplicon reference and the quantification window was set to 1bp around the cut site, as identified by providing the gRNA sequence. Computed alleles were quantified by measuring the number of reads and their relative abundance based on total read counts.
- Base editing options: `--base_editor_output --conversion_nuc_from <T/G> --conversion_nuc_to <C/A>` to measure the frequency of the expected nucleotide substitutions for the specific BE
