combine_kreports.py error

[sarrahroseml]

I created this script to iterate through the kreport files and run the combine_kreports.py file on them to combine. However, I am getting a ZeroDivisionError.

FILES=()
NAMES=()

for DIR in $(find $PARENT_DIR -mindepth 1 -maxdepth 1 -type d); do
    SAMPLE_NAME=$(basename $DIR)
    echo "Checking directory: $DIR"
    KRAKEN_FILE=$(find $DIR -type f -name "*.kraken")
    echo "Found file: $KRAKEN_FILE"

    if [ -n "$KRAKEN_FILE" ]; then
        FILES+=("$KRAKEN_FILE")
        NAMES+=("$SAMPLE_NAME")
    fi
done

# Convert arrays to space-separated strings
FILES_STR="${FILES[@]}"
NAMES_STR=$(IFS="," ; echo "${NAMES[*]}")

# Define the output file name
OUTPUT_FILE="${PARENT_DIR}/combined_kraken_output.txt"

# Print the gathered files and names for debugging
echo "Files: $FILES_STR"
echo "Names: $NAMES_STR"

# Run the combine_bracken_output.py script with the found files and sample names
python3 /global/scratch/projects/fc_wolflab/software/KrakenTools/combine_kreports.py -r ${FILES[@]} -o $OUTPUT_FILE
