Help Pages

calc_mappability A function to calculate the mappabilities of each NGS sample.
Evers_CRISPRn_RT112 A benchmark CRISPRn pooled screen data from Evers et al.
fit_ab A C++ function to perform a parameter estimation for the sgRNA-level test. It will estimate two different parameters 'phat' and 'vhat,' and we assume input count data follows the beta-binomial distribution. Dr. Keith Baggerly initially implemented this code in Matlab, and it has been rewritten it in C++ for the speed-up.
get_CPM A function to normalize sgRNA read counts.
join_count_and_design A function to join a count table and a design table.
measure_gene_stats A function to perform gene-level test using a sgRNA-level statistics.
measure_sgrna_stats A function to perform a statistical test at a sgRNA-level
plot_corr_heatmap A function to show a heatmap sgRNA-level corrleations of the NGS samples.
plot_count_distribution A function to plot read count distribution.
plot_dotplot A function to visualize dot plots for a gene.
plot_PCA A function to plot the first two principal components of samples.
quant A C++ function to quantify sgRNA abundance from NGS samples.
run_estimation A function to perform a statistical test at a sgRNA-level, deprecated.
run_sgrna_quant A function to run a sgRNA quantification algorithm from NGS sample
Sanson_CRISPRn_A375 A benchmark CRISPRn pooled screen data from Sanson et al.
