Working with PED files¶
The PED class¶
PED(PED, MAP, encoder = None):
PED - The ped file containing the genotype data.
MAP - The map file which contains labels for the snps in the ped file.
encoder - A pandas series which contains the reference/alternate alleles (eg. ‘A/G’) for each position with ids that correspond to the file. Defaults to None. Must provide one in order to get a genotype matrix.
- Data that was passed in parsed as a pandas dataframe.
- The map file parsed as a pandas dataframe.
- A pandas dataframe of the genotype data. 0 represents homozygous for the reference allele, 1 is heterozygous, and 2 is homozygous for the alternate allele.
