Hi

I am running GAPIT in R for GWAS. When I use external kinship and CV file the program shows error

Error in if ((n_gd + n_cv) > n_ran) { : argument is of length zero
In addition: There were 19 warnings (use warnings() to see them)

If i dont use these files it works. But I want to use these external files.

The code i used for GWAS

myY <- read.table("pythiumread_gwas.txt", head = TRUE)
myG <- read.table("Ca1-8_429_20042017_filtered_chiti_maf_0.05_missing_0.8_noCA_nocontig_noscaf_noLD.hmp.txt" , head = FALSE)
myCV <- read.table("mdp_population_structure.txt", head = TRUE)
myKI <- read.table("KI.txt", head = FALSE)
myGAPIT <- GAPIT(
  Y=myY,
  G=myG,
  CV=myCV,
  KI=myKI,
  model=c("GLM","MLM","MLMM","FarmCPU")
)

I would be grateful if you can tell me why I am getting this error.
