Nilearn: about the results of ward parcellation

Hi everyone,
After doing the parcellation step on fMRI epi with nilearn, i got the result like figure1. I wanna know why it just give the result like this. The input data i use is preprocessed with AFNI, and i tried this again using the data without doing the bandpass filter step, and it had not any problem as above, could anyone tell me what happened?

figure 1

Not sure what to tell to what happened by just looking at the figure. If you have a single-subject uploaded somewhere and access to me. I can try and see what is happening.

Please give me a script as well.


I use another command to do the preprocessing in AFNI, it works now, thank you!
