I have computed a contrast for each subject in first level, and now I’d like to run the second level analysis. I have three groups and I’m trying to run an ANOVA to compare the three groups:

```
design_matrix =
groupA groupB groupC
1 0 0
1 0 0
1 0 0
0 1 0
0 1 0
0 1 0
0 0 1
0 0 1
0 0 1
model = SecondLevelModel()
model.fit(contrast_map_filenames, design_matrix=design_matrix)
z_map = model.compute_contrast('group', output_type='z_score', second_level_stat_type='F')
```

Is this correct?
