do you think such an approach, while of theoretical interest, would produce a measurable improvement in some aspect of BOLD analysis? resting data, task data, anatomical accuracy, detection power? i would fear that the amount of improvement yielded by such a system may not justify the effort to build and validate it. that being said, we do have most of these components around and i would think that embedding them w/in a statistical framework might allow one to manage the parameters & information gained in a reliable way.

@stnava https://github.com/stnava - the issue on motion parameters raised the following thought process:
the BOLD or DWI epi timeseries is a product of motion, field inhomegeneity, susceptibility, slice-acquisition order and other artifacts, field of view. the impact of these issues varies based on age, head coil and sequence used. yet for most part these are addressed separately in the field. while there exists one algorithm currently to rectify slice acquisition timing and motion together (roche et al.) nothing takes all of this into account. i think the ITK/ANTS registration framework could potentially be augmented to address all of the above issues simultaneously. would love to hear your thoughts on this.

much easier to do now with antsr and/or antspy. recommend someone write pseudo-code for a recommended algorithm.
