Query regarding WGCNA module formation

Question

[microorganism_001]

I am trying to make a co-expression module with the following input gene-set associated standard division into a csv file and R-code but I'm getting error at the point of creating similarity matrix.- I first used

Geneid          Standard_Deviation
TEA_015735  136871.105296187
TEA_021485  90055.8355925799
TEA_008699  52986.1997835285
TEA_006622  52363.8854613665
TEA_024055  46407.075185256
TEA_020597  33511.1751584453
TEA_028572  29998.4692072409
TEA_001699  27893.7930167468
TEA_001579  25183.9331177197

workingData = read.csv("gene_count_matrix _sd.csv", header = T, row.names =1)

cordist <- function(dat) {
  cor_matrix  <- cor(t(dat))

  dist_matrix <- as.matrix(dist(dat, diag=TRUE, upper=TRUE))
  dist_matrix <- log1p(dist_matrix)
  dist_matrix <- 1 - (dist_matrix / max(dist_matrix))

  sign(cor_matrix) * ((abs(cor_matrix) + dist_matrix)/ 2)
}

sim_matrix <- cordist(workingData)

Error is following in R studio -

Error in cor(t(dat)) : 'x' has a zero dimension.

For reference, I Have installed the following libraries in R studio- WGCNA,
knitr,
reshape2,
limma,
gplots,
ggplot2,
RColorBrewer,

Hello,

The input data looks wrong:

To compute a similarity matrix you would need a matrix of normalized and log2 transformed gene expression vaues. If this is the first time you approach WGCNA, I suggest you go through the WGCNA tutorials instead of following some random guide in github.
