Error when running MetaCompass

[bgmfddg]

Hi,
I am running the following command:
python3 go_metacompass.py -r NC_040570.1.fasta -1 ERR2040215_1fp.fq -2 ERR2040215_2fp.fq -t 10

And I get the following error:

Do you have any idea why this is happening?

Did you try the readme examples first? Also, please check if mc.sam and mc.sam.all are empty or have very few lines.
