`IndexError` with format string

There is an issue with the following lines. The issue is that the format string is expecting two arguments but is only provided one. I guess this was not noticed before because it only happens when this exception is raised.

checkQC/checkQC/parsers/demux_summary_parser.py

Lines 52 to 54 in 6c7c39d

    
           raise DemuxSummaryNotFound("Could not identify expected demux summary file: {}. " 
        
                                      "We expect to find {} files matching the pattern, " 
        
                                      "'DemuxSummaryF1L<Lane number>.txt'".format(path))

	raise DemuxSummaryNotFound("Could not identify expected demux summary file: {}. "
