Dear Alexander,

Thank you very much for developing such a nice tool. I am using it to visualize the centromere repeats and it works very for most of the sequence. However, to some certain sequences, I have encountered an error with message "ZeroDivisionError: integer division or modulo by zero" (please see details below). Could you please let me know what is the possible reason behind and how can I solve it? The command I used was "moddotplot static -f 1.32M.fa -w 10000 -id 70 --no-plot -o ./".
