Hello, 

I'm for the first time trying the ImpulseDE function, but unfortunately Im having some error messages like: 

[1] "START: Prepare annotation table for internal usage"
[1] "-------------------------------------------------------------------"
[1] "Case condition: IR"
[1] "DONE"
[1] "###################################################################"
[1] "START: Clustering genes for Impulse model fit"
[1] "-------------------------------------------------------------------"
[1] "Clustering of case data set"

Error in t.default(apply(dat_pre, 1, function(y) { : 
  argument is not a matrix
In addition: Warning message:
In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL'

expression table is a numeric matrix and if separately I apply is.na() to the expression data, there is no problem. I cant get where is the error? 

Any help please? Thank you in advance.
