                    pathname

positional arguments:
  pathname              An unix grob style filename pattern for the data files

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit

Reading options:
  -p PARSER, --parser PARSER
                        A maidenhair parser name which will be used to parse
                        the raw text data.
  -l LOADER, --loader LOADER
                        A maidenhair loader name which will be used to load
                        the raw text data.
  -u USING, --using USING
                        A colon (:) separated column indexes. It is used for
                        limiting the reading columns.
  -a, --average         Calculate the average value of the specified data.
  -s, --no-strict       Do not strict the wavelength range into 190-240 .
  -o OUTPUT, --output OUTPUT
                        A output filename. The default is "contin-cd.in".

Experimental properties:
  -n NUMBER, --number NUMBER
                        The number of residues (amino acids) in the sample.
  -m MOLECULAR_WEIGHT, --molecular-weight MOLECULAR_WEIGHT
                        A molecular weight of the sample in kDa (=kg/mol).
  -c CONCENTRATION, --concentration CONCENTRATION
                        A concentration of the sample in g/L. See --molar-
                        concentration as an alternative.
  --molar-concentration MOLAR_CONCENTRATION
                        A molar concentration of the sample in mol/L. It is
                        used as an alternative option of --concentration.
  -L LENGTH, --length LENGTH
                        A light pathway length (cuvette length) in centimeter
