synopsis

/home/darya/.local/lib/python3.6/site-packages/pypreprocess/reporting/glm_reporter.py in <listcomp>(.0)
     84                                 height_control=height_control)
          85     if clusters is not None:
          ---> 86         clusters = [c for c in clusters if c['cluster_p_value'] < cluster_pval]
               87     else:
                    88         clusters = []

TypeError: '<' not supported between instances of 'NoneType' and 'float'

Notes

The problem does happen under python 2

Probably related to "slice timing broken in python 3k" issue #285, since it seems that pypreprocess is not python 3.5 compliant.

I try to take a look.
