ImSig Error

[eabybee]

I am running into a problem when I am running ImSig. My input file is a normalized counts file that has HGNC gene symbols in the first column, and normalized read counts for each of my samples. I have followed the Github tutorial in running ImSig in R. I have changed the first column to rownames and my file looks like the example data set built into ImSig from what I can tell. Yet, when I run ImSig I am getting the following error:

imsig(Norm_TME_Alone_KRAS)

I am unable to determine what is going wrong, and what I need to change. Here is an example of the first few lines of my data frame.
