This bug was report [here](https://github.com/dipy/dipy/issues/2541) and concerns ndarray.min() causing coverage tests to fail (note that numpy.min(ndarray) works fine). It seems very difficult to reproduce, but in short using a command...
The functions in dipy/align/_public, which conveniently allow to register entire dwi series, are only designed to work with 3D volumes, i.e. 4D data, in which the acquisitions are in the...
DKI fitting was not allowing to save S0 so I have made some updates.
https://github.com/dipy/dipy/blob/7e158ffa52b81710f3a1b0d6afa3a364f42a650c/dipy/reconst/dki.py#L1678 I think, as mentioned in #2730, that the masking in the DKI function is not working properly except for the `multi_fit` method, because the mask does not appear to...
Although this is perhaps a Fury question, I feel that in this case it really belongs here. The BIDS compliant NIfTI format species a left-handed coordinate system (radiological convention). The...
## Description Manjon 2013 paper "Diffusion Weighted Image Denoising Using Overcomplete Local PCA" provides a method to estimate noise in a diffusion weighted image series using PCA. I believe that...
Adds ability to do iteratively re-weighted least squares for DTI and DKI (with/without positivity constraints) by defining a function to return weights based on the residuals of the last fit....
I am checking through some of the tests for reconst/dti, and I am finding (after some changes made for an up and coming PR) that the checks on the non-linear-least-squares...
I need some help figuring out if there is a problem with constrained WLS in the DKI module. See `dipy/reconst/dki.py` https://github.com/dipy/dipy/blob/e5cc120bf6c5c271f32cced62150157abd15a321/dipy/reconst/dki.py#L2611-L2619 So here we see that, in order to solve...
Attempt to replace #3170 after rebasing on changes made in #3323 Probably need help from @arokem and @skoudoro on this
