Hi

I am using the maSigPro package but unfortunately I get an error that I can not find the solution to. 

> see.genes(sigs, edesign = designMa, show.fit = T, dis = designMa$dis, cluster.method = "kmeans", cluster.data = 1, k = 9) 
[1] "warning: no rows without missing values or less than 2 rows; impossible to compute heatmap"

C_a2_t30        1  0
C_a2_t90        1  0

I have run the procedure with log2 values, linear values, with and without (used impute.knn) missing values but still get the error. Any suggestions?
