Hi all, I am working with a script that generates peaks using dipy's peaks_from_model() to track white matter pathways. I am attempting to save these peaks to a nifti from the .PAM5 file they are saved in using save_peaks(). My PeaksandMetrics object does not have the affine attribute, however even if I specify it in save_peaks() as the docs suggest it still fails to recognize it and gives the error:
AttributeError: 'PeaksAndMetrics' object has no attribute 'affine'. I am using dipy 0.15, python 2.7 . Here is my code, any advice is helpful since I am still fairly new to dipy:
`csapeaks = peaks_from_model(model=csa_model,
pam = savepeaks(os.path.join(Diffusion, 'peaks.pam5'), csapeaks, affine=np.eye(4))
Hi, a question for the community: I would need to cluster streamline pairs rather than streamlines whilst still using QuickBundles. By this I mean that I have one streamline pair [A B], where A and B are individual streamlines, and one streamline pair [C D], where C and D are individual streamlines. What I want to do is calculate the distance between A and C, and B and D and cluster based on the total distance between the pairs as: totalDistance = distanceBetween(A, C) +distanceBetween(B, D).
If anyone has any idea of how to achieve this I would be very thankful to hear it!
