Error with missing library but output still generated?

[mhyleung]

Dear all

I tried to run CRISPRtracrRNA with a contig containing a Class V Cas operon:

python CRISPRtracrRNA.py \
--input_folder [input_directory] \
--output_folder [output_directory] \
--run_type complete_run --model_type V --perform_type_v_anti_repeat_analysis True

I got the following output

    anti_repeat_interval = line_elements[anti_repeat_index]

However, I am still able to get the output .csv file. I thought it was not able to predict the anti-repeat region, but the anti-repeat sequences are there in the final .csv file.

I just want to know what the basis of the error is and how I would go about removing it. Thanks
