Hi i am using Clinker and it gives following error-

clinker P_aeruginosa_AR_0110.gbk P_aeruginosa_AR_0111.gbk P_aeruginosa_AR_455.gbk P_aeruginosa_ATCC_15692.gbk -r 4_dataforcli.txt -o out_4 -i 70 -p 4_plot.html

^^^^^^^^^^^^^^^^^^^^^

The above exception was the direct cause of the following exception:

And data 4_dataforcli.txt look like-

Chr1:215234-216385
Chr1:3817094-3818245
chr1:1837109-1838260
Chr1:471545-472696

If anyone know anything please let me know.

Thank you!
