Run with one sample


When I run the classifier with one sample,
I get error below:

```
Error in `rownames<-`(`*tmp*`, value = ebpp_genes_sig$Symbol) : 
  attempt to set 'rownames' on an object with no dimensions
Calls: capture.output ... withCallingHandlers -> <Anonymous> -> geneMatch -> rownames<-
Execution halted
```

With two samples,  it works smoothly.
