Problem running the example dataset

Hi

I have just downloaded the SIMA package and tried to run your example dataset from www.losonczylab.org/workflow_data.zip.
I've got the following error:
Traceback (most recent call last):

Any suggestions or advice you might have would be greatly appreciated.

Thanks,
