Problem with kaiju2anvio.R

Hi
I am running intro an error when running kaiju2anvio.R script after kaiju taxonomic assignment.
The error is the following:

```
Loading required package: parallel
Error in `[.data.frame`(kaiju.names, , 2) : undefined columns selected
Calls: kaiju2mat -> cbind -> as.matrix -> [ -> [.data.frame
Execution halted
```

Any help would be appreciated.

Thanks.
