run_dtw: Get network adjacency dataframe based on DTW method

Description

Use DTW to calcuate gene-gene distance based on their expression and pseudotime

Usage

run_dtw(
  expression_matrix,
  pseudotime_list,
  slide_window_size = 50,
  slide_step_size = 25,
  quantile_cutoff = 5,
  cores = 1
)

Value

adjacency dataframe (with columns "from, to, distance,direction, similarity")

Arguments

expression_matrix

expression matrix data

pseudotime_list

list of pseudotime

slide_window_size

sliding window size

slide_step_size

sliding window step size

quantile_cutoff

an integer value (1-99) for quantile cutoff

cores

number of cores for parallel computing

Examples

example_data <- pGRNDB
expression_matrix <- example_data[["expression"]]
pseudotime_list <- example_data[["ptime"]]$PseudoTime
adj_df <- run_dtw(expression_matrix,
                  pseudotime_list,
                  quantile_cutoff=50,
                  cores=1)
