MedINRIA INR file with DIPY
by Animesh Ranjan 19 Sep '19

Hello Dipy-Team, I am looking to replace an existing dMRI segmentation workflow created using MedINRia with DIPY. While performing fibre tracking with MEdINRIA, the files .FIB and .INR are written out, corresponding to the defined RoI. Writing out FIB with DIPY is pretty straight-forward with DIPY but is there a way to write out the INR files as well. In general, INR file contains the volume image information representing at each voxel a tensor T containing full diffusion information which can be then extracted using the ReadInrTensorData() in MATLAB. Is there a way to generate this for a streamline object in DIPY? Any help will be greatly appreciated. Kind Regards, *Animesh Ranjan,* *Development Engineer - Fraunhofer Institute for Manufacturing Engineering & Automation IPA* *Doctoral Candidate - University of Stuttgart* *Nobelstraße 12,* *70569 Stuttgart,* *Deutschland.*

questions regarding the probability maps of DIPY MAPMRI estimator

Hi DIPY developers, Are those probability maps of MAPMRI comparable between subjects? Why the intensity values of probability maps are not in the scale of [0 1]? Thanks. Ping

[DIPY] Comments about issues raised in the Sept 10th dev meeting

Hi, a few comments following yesterday's dev meeting. As for the GitHub CI, I was curious. I guess this is what Ariel mentioned: https://github.blog/2019-08-08-github-actions-now-supports-ci-cd/ The YAML mechanism seems very similar to the Microsoft Azure Pipelines. The page says it is free for open source projects: https://github.com/features/actions Looks promising. As said, ITK moved to Azure Pipelines a while ago and they are very happy with it. On the new website, I ignore whether you finally kept the suggestion, but making all tutorials be folded/unfolded with a button seems very useful to me. As for the support channels, until recently I was not aware that there was a DIPY mailing list separate from the neurostars mailing list/forum. DIPY has also a gitter room. I'd dare to say that having a centralized channel for questions (although these days GitHub issues are also used to post questions, same may happen in twitter, etc.) would ease things for both users ans maintainers, since "everything" would be kept in the same site, and searchable. IMHO, discourse (a DIPY-own, separate from neurostars) is a very nice option for this. BTW, the new DIPY website looks stunning. Excellent job ! Cheers, JON HAITZ
