ValueError: On entry to DLASCL parameter number 4 had an illegal value

[charlesgwellem]

Thanks for this very promising package. I am trying to apply this tool on single cell RNA seq data, of once cell type that has been sorted out. I have treatment vs control samples. However on following this tutorial, I encounter the following error. I do not have any NAs in the data set. Please how could I fix this?

gene_names = gene_exp_diff_1.columns.values

scaler = StandardScaler(with_std=False)
X1 = scaler.fit_transform(gene_exp_diff_1.values)
X2 = scaler.fit_transform(gene_exp_diff_2.values)

d_dag = dci(X1, X2, alpha_ug = 0.001, alpha_skeleton=0.5, alpha_orient=0.001, max_set_size=3, verbose=1)
