MAGeCK can be used for prioritizing single-guide RNAs, genes and pathways in genome-scale CRISPR/Cas9 knockout screens. MAGeCK identifies both positively and negatively selected genes simultaneously and reports robust results across different experimental conditions. MAGeCK is developed and maintained by Wei Li and Han Xu from `Prof. Xiaole Shirley Liu's lab`_ at the Department of Biostatistics and Computational Biology, Dana-Farber Cancer Institute and Harvard School of Public Health. MAGeCK has been used to identify functional lncRNAs from screens with close to `100% validation rate`_. .. _`Model-based Analysis of Genome-wide CRISPR-Cas9 Knockout`: https://genomebiology.biomedcentral.com/articles/10.1186/s13059-014-0554-4 .. _`100% validation rate`: https://sourceforge.net/p/mageck/wiki/Home/ .. _`Prof. Xiaole Shirley Liu's lab`: http://liulab.dfci.harvard.edu/ ----- **mageck test** This tests and ranks sgRNAs and genes based on the table provided. **Inputs** **sgRNA count file** The input sgRNA count file be tab-delimited and list the names of the sgRNA, the gene it is targeting, followed by the read counts in each sample. A header line is optional. For example in the studies of T. Wang et al. Science 2014, there are 4 CRISPR screening samples, and they are labeled as: HL60.initial, KBM7.initial, HL60.final, KBM7.final, see below. Example: ============== ======== ================ ================ ============== ============== **sgRNA** **gene** **HL60.initial** **KBM7.initial** **HL60.final** **KBM7.final** -------------- -------- ---------------- ---------------- -------------- -------------- A1CF_m52595977 A1CF 213 274 883 175 A1CF_m52596017 A1CF 294 412 1554 1891 A1CF_m52596056 A1CF 421 368 566 759 A1CF_m52603842 A1CF 274 243 314 855 A1CF_m52603847 A1CF 0 50 145 266 ============== ======== ================ ================ ============== ============== **Sample Labels** In the Treatment and Control inputs above, you can use either Sample Label or Sample Index to specify samples. If sample label is used, the labels MUST match the sample labels in the first line of the count table. For example, "HL60.final,KBM7.final". You can also use sample index to specify samples. The index of the sample is the order it appears in the sgRNA read count file, starting from 0. The index is used in the Treatment and Control inputs. In the example above, there are four samples, and the index of each sample is as follows: ============ ======= *sample* *index* ------------ ------- HL60.initial 0 KBM7.initial 1 HL60.final 2 KBM7.final 3 ============ ======= **Control sgRNA file** The optional Control sgRNA file is used to generate null distribution when calculating the p values. If this option is not specified, MAGeCK generates the null distribution of RRA scores by assuming all of the genes in the library are non-essential. This approach is sometimes over-conservative, and you can improve this if you know some genes are not essential. By providing the corresponding sgRNA IDs in this option, MAGeCK will have a better estimation of p values. To use this option, you need to prepare a text file specifying the IDs of control sgRNAs, one line for one sgRNA ID. ----- **Outputs** **sgRNA Summary file** An example of the sgRNA ranking output is as follows: ================ ======== ================= =================== ================ ============== ======= =============== =========== ========= ========= =========== ============== =========== ===================== **sgrna** **Gene** **control_count** **treatment_count** **control_mean** **treat_mean** **LFC** **control_var** **adj_var** **score** **p.low** **p.high** **p.twosided** **FDR** **high_in_treatment** ---------------- -------- ----------------- ------------------- ---------------- -------------- ------- --------------- ----------- --------- --------- ----------- -------------- ----------- --------------------- INO80B_m74682554 INO80B 0.0/0.0 1220.15/1476.14 0.810860 1348.15 10.70 0.0 19.0767 308.478 1.0 1.11022e-16 2.22044e-16 1.57651e-14 True NHS_p17705966 NHS 1.62172/3.90887 2327.09/1849.95 2.76529 2088.52 9.54 2.61554 68.2450 252.480 1.0 1.11022e-16 2.22044e-16 1.57651e-14 True ================ ======== ================= =================== ================ ============== ======= =============== =========== ========= ========= =========== ============== =========== ===================== The contents of each column are as follows: * **sgrna** sgRNA ID * **Gene** The targeting gene * **control_count** Normalized read counts in control samples * **treatment_count** Normalized read counts in treatment samples * **control_mean** Mean read counts in control samples * **treat_mean** Mean read counts in treatment samples * **LFC** The log fold change of sgRNA * **control_var** The raw variance in control samples * **adj_var** The adjusted variance in control samples * **score** The score of this sgRNA * **p.low** p-value (lower tail) * **p.high** p-value (higher tail) * **p.twosided** p-value (two sided) * **FDR** false discovery rate * **high_in_treatment** Whether the abundance is higher in treatment samples **Gene Summary file** An example of the gene summary output file is as follows: ======= ======= ============= =============== =========== ============ ================= =========== ============= =============== =========== ============ ================= =========== **id** **num** **neg|score** **neg|p-value** **neg|fdr** **neg|rank** **neg|goodsgrna** **neg|lfc** **pos|score** **pos|p-value** **pos|fdr** **pos|rank** **pos|goodsgrna** **pos|lfc** ------- ------- ------------- --------------- ----------- ------------ ----------------- ----------- ------------- --------------- ----------- ------------ ----------------- ----------- ESPL1 12 6.4327e-10 7.558e-06 7.9e-05 1 -2.35 11 0.99725 0.99981 0.999992 615 0 -0.07 RPL18 12 6.4671e-10 7.558e-06 7.9e-05 2 -2.12 11 0.99799 0.99989 0.999992 620 0 -0.32 CDK1 12 2.6439e-09 7.558e-06 7.9e-05 3 -1.93 12 1.0 0.99999 0.999992 655 0 -0.12 ======= ======= ============= =============== =========== ============ ================= =========== ============= =============== =========== ============ ================= =========== The contents of each column is as follows: * **id** Gene ID * **num** The number of targeting sgRNAs for each gene * **neg|score** The RRA lo value of this gene in negative selection * **neg|p-value** The raw p-value (using permutation) of this gene in negative selection * **neg|fdr** The false discovery rate of this gene in negative selection * **neg|rank** The ranking of this gene in negative selection * **neg|goodsgrna** The number of "good" sgRNAs, i.e., sgRNAs whose ranking is below the alpha cutoff (determined by the --gene-test-fdr-threshold option), in negative selection. * **neg|lfc** The log fold change of this gene in negative selection * **pos|score** The number of targeting sgRNAs for each gene in positive selection (usually the same as num.neg) * **pos|score** The RRA lo value of this gene in negative selection * **pos|p-value** The raw p-value of this gene in positive selection * **pos|fdr** The false discovery rate of this gene in positive selection * **pos|rank** The ranking of this gene in positive selection * **pos|goodsgrna** The number of "good" sgRNAs, i.e., sgRNAs whose ranking is below the alpha cutoff (determined by the --gene-test-fdr-threshold option), in positive selection. * **pos|lfc** The log fold change of this gene in positive selection Genes are ranked by the p.neg field (by default). If you need a ranking by the p.pos, you can use the --sort-criteria option. ----- **More Information** **Overview of the MAGeCK algorithm** Briefly, read counts from different samples are first median-normalized to adjust for the effect of library sizes and read count distributions. Then the variance of read counts is estimated by sharing information across features, and a negative binomial (NB) model is used to test whether sgRNA abundance differs significantly between treatments and controls. This approach is similar to those used for differential RNA-Seq analysis. We rank sgRNAs based on P-values calculated from the NB model, and use a modified robust ranking aggregation (RRA) algorithm named α-RRA to identify positively or negatively selected genes. More specifically, α-RRA assumes that if a gene has no effect on selection, then sgRNAs targeting this gene should be uniformly distributed across the ranked list of all the sgRNAs. α-RRA ranks genes by comparing the skew in rankings to the uniform null model, and prioritizes genes whose sgRNA rankings are consistently higher than expected. α-RRA calculates the statistical significance of the skew by permutation, and a detailed description of the algorithm is presented in the Materials and methods section of the `MAGeCK paper`_. Finally, MAGeCK reports positively and negatively selected pathways by applying α-RRA to the rankings of genes in a pathway.
