...For all remaining genes, 5-10 candidate sgRNAs were selected with a preference for sequences ordered by (1) the number of matches elsewhere in the genome (2) the number of 1-bp mismatched guide sequences that map elsewhere in the genome (3) the number of transcript models targeted for a given gene (4) the sgRNA score as predicted by the sgRNA efficacy algorithm and (5) the position along the transcript....

...The target sequences (each encoded by a vector of 80 binary variables representing the presence or absence of each nucleotide (A, C, T, G) at each position (1-20) along the target sequence) of ribosomal protein gene-targeting sgRNAs were used as inputs to the classifier which was trained on the change in abundance observed (encoded by a binary variable corresponding to ‘weak’ and ‘strong’ sgRNAs using a cutoff based on the bimodality of the distribution)....
