Problem with FFPopSim

[ang-one]

Hi,

I am trying to run your program in order to simulate a neutral evolution.

However, every example I try to run ends with some errors.
Following, I report two of them.

If I run benefits_of_sex.py I have the following error:
''Traceback (most recent call last):
File "benefits_of_sex.py", line 32, in
pop.set_trait_additive(np.ones(L)*params.sel) # set additive contribution of each locus to s
File "../pkg/python/FFPopSim.py", line 3404, in set_trait_additive
if (len(args) > 1) and (args[1] >= self.number_of_traits):
NameError: global name 'args' is not defined''

Instead, if I run infinite_sites_model.py, I obtain:
Traceback (most recent call last):
File "infinite_sites_model.py", line 18, in
pop.all_polymorphic=True
AttributeError: can't set attribute

Could you help me to solve this issue?
Thank you for your attention.

Greetings,
Fabrizio
