Error while performing MrBam with Python 3.6.8

[EricSoulsurfer]

I have some issue when running MrBam.

line 31, in anno
    pos =int(line[1]) - 1
ValueError: invalid literal for int() with base 10: 'Start'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "Mrbam.py", line 86, in <module>
    anno(o)
  File "/home/rico/Downloads/MrBam-master/MrBam/anno.py", line 33, in anno
    raise Exception("vcf header should be expluded", o.query)
Exception: ('vcf header should be expluded', '/home/rico/Downloads/TagSequencing.snp.hg19_multianno.txt')
