### Diversity statistics ###

For each island there are two datafiles:

*_all_stats.txt		All diversity statistics (prior to filtering)
*_filtered_stats.txt	Filtered diversity statistics

Rowan’s are locus IDs.

Column names in each file are:

he	expected heterozygosity
ho	observed heterozygosity
n_all	number of alleles
rhat1	rhat - estimated frequency of null alleles in the wave population
rhat2	as above but in the crab population
rmax1	maximum possible value of rhat in wave population
rmax2	as above but in crab population
fst	W+C raw fst
fit	W+C raw fit
fis	W+C raw fis
wc_he	W+C he
corr_fst	rhat corrected fst
corr_fit	rhat corrected fit
corr_fis	rhat corrected fis
corr_wc_he	rhat corrected wc_he
corr_fst_mr	mean rhat corrected fst
corr_fit_mr	mean rhat corrected fit
corr_fis_mr	mean rhat corrected fis
corr_wc_he_mr	mean rhat corrected wc_he
het_f	number of heterozygous females
hom_f	number of homozygous females
het_m	number of heterozygous males
hom_m	number of homozygous males
auto_df	degrees of freedom under autosomal model
auto_g	g-statistic under autosomal model
sex_df	degrees of freedom under sex-linked model
sex_g	g-statistic under sex-linked model
maf	major allele frequency
nind	number of individuals scored
hom_depth	mean homozygote depth
het_depth	mean heterozygote depth
nhom	number of homozygotes
nhet	number of heterozygotes
hom_het_ratio	homozygote:heterozygote ratio
loc_depth	mean depth at locus
he	expected heterozygosity (across all populations)
ho	observed heterozygosity (across all populations)
n_fis	fis
nind_a	nind genotyped
obs_exp_hom	ratio of obs to exp homozygosity
llr	log-likelihood ratio
chr	chromsome - i.e. autosomal or sex-linked
maf_cutoff	factor - does locus exceed MAF cutoff?
