The `achilles` dataset contains the metadata for DepMap’s cancer models/cell lines, specific to Project Achilles’ 22Q2 CRISPR screens. This dataset can be loaded into the R environment with the `depmap_achilles` function.

Usage

achilles

Format

A data frame with 1036 rows and 6 variables:

depmap_id

cancer cancer cell line foreign key (i.e. "ACH-00001")

cell_line

CCLE name of cancer cell line (i.e. "184A1_BREAST")

achilles_n_replicates

Number of replicates used in Achilles CRISPR screen passing QC

cell_line_NNMD

Difference in the means of positive and negative controls normalized by the standard deviation of the negative control distribution

culture_medium

Medium used to grow cell line

cas9_activity

Percentage of cells remaining GFP negative on days 12-14 of cas9 activity assay as measured by FACs
