configuration_example_2_of_2.ini

# This is the second part of example configuration files for performing
# efficient data clean up. All commented out parameters are those that are used
# by default.

# The input file should be the output file of the second sample missigness step
# (which is the one that has been used by any of these scripts):
#    - sex_check
#    - find_related_samples
#    - check_ethnicity
#    - plate_bias

# Note that the final usable dataset is the one located in the directory where
# "remove_heterozygous_haploid" was run (which is the one that has been used by
# any of these scripts):
#    - flag_maf_zero
#    - flag_hw
# Hence, if you want to remove the flagged markers, you should use
# pyGenClean_subset_data on markers in the "flag_maf_zero" and "flag_hw"
# directories using the PLINK's binary file located in
# "remove_heterozygous_haploid".

# of markers to exclude from steps [6]. Just create a file containing family and
# individual identification numbers for all those samples to remove. Note that
# the two options 'reason-marker' and 'reason-sample' are for the automatic
# report generated after the analysis.
