`build_net` error

[gurpreet-bioinfo]

Hi @Kumquatum @nturaga I am getting the following error for build_net while using rnaseq counts ( > 20 samples) with default option as per the tutorial. Everything went well until this step.

the standard deviation is zeroError in if (min(cor_mat < -1) | max(cor_mat) > 1) stop("Provided correlation function returned values outside [-1,1].") : 
  missing value where TRUE/FALSE needed

My command is:
net = build_net(counts_fil, cor_func = "spearman", n_threads = 2)

Any pointers please?
Thanks.
