8.1.2 How do I load multiple pedigrees in one program?

A PyPedal program can load more than one pedigree at a time. Each pedigree must be passed its own options dictionary, and the pedigrees must have different names. This is easily done by creating a dictionary with global options and customizing it for each pedigree. Once you have created a pedigree by calling pyp_newclasses.NewPedigree('options') you can change the options dictionary without affecting that pedigree (a pedigree stores a copy of the options dictionary in its kw attribute). The following code fragment demonstrates how to read two pedigree files in a single program:

#   Create the empty options dictionary
options = {}

#   Read the first pedigree
options['pedfile'] = 'new_lacy.ped'
options['pedformat'] = 'asd'
options['pedname'] = 'Lacy Pedigree'
example1 = pyp_newclasses.loadPedigree(options)

#   Read the second pedigree
options['pedfile'] = 'new_boichard.ped'
options['pedformat'] = 'asdg'
options['pedname'] = 'Boichard Pedigree'
example2 = pyp_newclasses.loadPedigree(options)

Note that pedformat only needs to be changed if the two pedigrees have different formats. You do not even have to change pedfile.
