CITMIC is a method for estimate cell infiltration score
CITMIC can infer the cell infiltration of the TME by simultaneously measuring 86 different cell types, constructing an individualized cell-cell crosstalk network based on functional similarities between cells, and using only gene transcription data. This is a novel approach to estimate the relative cell infiltration levels, and which were shown to be superior to the current methods.

parallel::detectCores(). He will greatly improve the efficiency of the function's operation.Install CITMIC using:
install.packages(c('devtools', 'BiocManager'))
remotes::install_github("zhaopapers/CITMIC")
Load the package using library(CITMIC). We provide a vignette for the package that can be called using: vignette("CITMIC").
Alternatively, you can view the online version on CRAN, The examples I provided would take several minutes to run on a normal desktop computer. Basically that is all you have to know.
