# ### Getting additional information about samples

# In[10]:

#Again, use list comprehension to get the 'details' of each sample
#Given that each object in samples is a tuple, and that the second
#item in each tuple represents selected mutations, i[1] in the line
#below means that we are getting the mutation information only for
#selected variants
details = [fp.get_sample_details(i[1],j) for i,j in zip(samples,pops)]


# In[11]:

#details is now a list of pandas DataFrame objects
#Each DataFrame has the following columns:
#  a: mutation age (in generations)
#  h: dominance of the mutation
#  p: frequency of the mutation in the population
#  s: selection coefficient of the mutation
#  label: A label applied for mutations for each region.  Here, I use 0 for all regions
