CytoSignal & VeloCytoSignal is a tool for detecting static and dynamic cell-cell signaling at cellular resolution from spatial transcriptomic data. Our tools are applicable to most sequencing-based and probe-based spatial transcriptomic techniques, such as Slide-seq, Stereo-seq, and MERFISH, requiring only a cell-by-gene matrix and a cell-by-spatial-position matrix.

The package is developed and tested under R>=4.2.0. Users can install R following the instruction provided on CRAN. To install CytoSimplex & VelcoCytoSignal in R, run the following command in an R console:
if (!requireNamespace("devtools", quietly = TRUE))
install.packages("devtools")
devtools::install_github("welch-lab/cytosignal")We are currently working on releasing a CRAN version. Stay tuned!
