Here is a link to the data I’m working with.
I try creating a group based on the columns I want (cuepos, targetpos and soa), but when I list the groups, it seems to be creating groups with some of the other columns as well…
groups = t.groupby(['cuepos', 'targetpos', 'soa'])
for name, _ in groups:
print name
Output:

The desired groups are in the middle (the ones that look like (1, 1, -0.1)). What’s this other stuff? What am I doing wrong, here?
Well, the data isn’t lying about the observed 3-tuples:
