pdatafile

Combined datafile and parameterfile

• All lines before the header line (starting with #! ) that begin with #\ are interpreted as parameter file data

• if these are present a parameterfile object is created : pf.par (pf is the name of the pdatafile object) if nothing was present the value of pf.par is None

Example data:

#\ my_var = 5.0   
#\ my_other_var = 10.0
#
# just a regular comment
#
# the data start below
#! p_miss[0]/ siglt[2]/ s01[3]/ alt[4]/
200. 1.35e-4 -1.e-3    0.1
220. 2.56e-4 -2.e-4    -0.1
230. 3.47e-6 -3.e-5    1.1

Opening this file as following

>>> from LT.pdatafile import pdfile
>>> pp = pdfile('my_file.data')

To get the raw (string) values

>>> pp.par.get_data('my_var')

To see all variables and their values

>>> pp.par.show_all_data()

To convert the value to e.g. a float or a bool

>>> x = pp.par.get_value('my_var')

To convert to an int:

>>> i = pp.par.get_value('my_var', var_type = int)
>>> j = pp.par.get_value('my_var', var_type = int)

In general pp.par is a pfile object attached to a dfile.

class LT.pdatafile.pdfile(filename, debug=False, **kwargs)

open a pdata file an scan the contents for for a format that can be interpreted

example:

>>> pp=pdfile('my_datafile')

add_parameter(name, value)

add a parameter to the file, it will be saved into a new file with write_all(file_o, complete_header = True)

set_parameter(name, value)

set a parameters value in the header so that it is saved when the file is saved with full header

name: variable name value: the value to be stored this MUST be a string
