MNI rigid-body output space

### What would you like to see added in fMRIPrep? Specify a new output space, which involves applying only the rigid-body component of the transformation to MNI space. ### Do...

Incorrect multi-echo detection with multiple runs

### What happened? Following a seemingly inconsequential change to file names, multi-echo processing is no longer activated. ----- We have previously executed on multiple multi-echo fMRI runs without issue. Our...

[ENH] Inheritance principle: Relaxation allowing multiple files per directory

22

Closes #259. Was raised in discussion more recently in #946, the changes contained within were intended to facilitate this new set of changes. For anyone curious about the underlying motivation...

[ENH] Extensive use of definition hyperlinks

5

Originally listed in Lestropie/bids-specification#1, but warrants its own listing. The theory is that if there exists within the specification a strict list of definitions, with centralised precise definitions of terms,...

FreeSurfer execution when both T2w and FLAIR present

4

### What would you like to see added in fMRIPrep? When both T2w and FLAIR acquisitions are present (both high resolution isotropic) in the input session, it is necessary to...

RobustICA behaviour on non-convergence

3

I want to discuss a confound intrinsic to #1013, which, given its esoteric nature, I felt better to write as a separate Issue so as to not cross-contaminate discussions. For...

-tedpca command-line interface

Relates to discussion in #949. Note that I am approaching this as someone with no experience with specifically TEDANA, but plenty of experience in research software. In `23.0.x`, there is...

Entities applicable to derivatives only

In stalking the Copenhagen BIDS Derivatives meeting, I passed comment on the fact that as the scope of BIDS Derivatives increases, there will be an increasing number of entities that...

Magnitude image(s) in MRI phasediff fmap

Seeking clarification on ["Types of fieldmaps" - "Case 1: Phase-difference map and at least one magnitude image"](https://bids-specification.readthedocs.io/en/v1.8.0/04-modality-specific-files/01-magnetic-resonance-imaging-data.html#case-1-phase-difference-map-and-at-least-one-magnitude-image). I only have conceptual knowledge of this technique, not hands-on experience, so want...

Hi @codeplea, I [made use of](https://github.com/MRtrix3/mrtrix3/blob/3.0.4/core/math/betainc.cpp) this function in [the *MRtrix3* software](https://www.mrtrix.org/) to deal with compilation on systems where our primary mathematics library dependency, [Eigen](https://eigen.tuxfamily.org/), is missing [the corresponding function](https://eigen.tuxfamily.org/dox/unsupported/namespaceEigen.html#title18)....
