        FileRecord

Holds information from a GenePop record.

Attributes: - marker_len The marker length (2 or 3 digit code per allele). - comment_line Comment line. - loci_list List of loci names.

Methods: - get_individual Returns the next individual of the current population. - skip_population Skips the current population.

skip_population skips the individuals of the current population, returns True if there are more populations.

get_individual returns an individual of the current population (or None if the list ended).

Each individual is a pair composed by individual name and a list of alleles (2 per marker or 1 for haploid data). Examples:

('Ind1', [(1,2),    (3,3), (200,201)]
('Ind2', [(2,None), (3,3), (None,None)]
('Other1', [(1,1),  (4,3), (200,200)]

Method Details [hide private]

__init__(self, fname)
(Constructor)

source code 
x.__init__(...) initializes x; see help(type(x)) for signature
Overrides: object.__init__
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 

Returns (reconstructs) a GenePop textual representation.

This might take a lot of memory. Marker length will be 3.

Overrides: object.__str__

seek_position(self, pop, indiv)

source code 

Seeks a certain position in the file.

Arguments:
  • pop - pop position (0 is first)
  • indiv - individual in pop

get_individual(self)

source code 

Gets the next individual.

Returns individual information if there are more individuals in the current population. Returns True if there are no more individuals in the current population, but there are more populations. Next read will be of the following pop. Returns False if at end of file.

remove_population(self, pos, fname)

source code 

Removes a population (by position).

Arguments:
  • pos - position
  • fname - file to be created with population removed

remove_locus_by_position(self, pos, fname)

source code 

Removes a locus by position.

Arguments:
  • pos - position
  • fname - file to be created with locus removed

remove_loci_by_position(self, positions, fname)

source code 

Removes a set of loci by position.

Arguments:
  • positions - positions
  • fname - file to be created with locus removed

remove_locus_by_name(self, name, fname)

source code 

Removes a locus by name.

Arguments:
  • name - name
  • fname - file to be created with locus removed

remove_loci_by_name(self, names, fname)

source code 

Removes a loci list (by name).

Arguments:
  • names - names
  • fname - file to be created with loci removed
