The CIBERSORTx web portal (https://cibersortx.stanford.edu/) was used to run CIBERSORTx in “Impute Cell Fractions” mode. The tool was run using the provided LM22 signature matrix in conjunction with the TCGA TNBC FPKM data. “B-mode” batch correction was used based on the LM22 source GEP file, with quantile normalization disabled. 100 permutations were used for significance testing.
