Clarifications on input structure for most functions

[gdevenyi]

When working with our various quantitative imaging components, we follow a BIDSified format where all our inputs are separate files. It appears various functions in QUIT require images with stacked-dimensionality of some kind to store multiple image inputs for processing (ex #37)

Could you please provide some additional documentation on the expected input format for the various functions? Thanks!

All the QUIT commands require the main inputs to be "stacked" along the 4th / time dimension in the input nifti file. My own qMRI sequences on GE write out DICOMs that will convert to the corresponding niftis, and I find the format to be far more convenient to work with than separate files. For instance, CEST experiments usually have >20 offset frequencies, it's much easier to have one file than 20 separate ones. It's also the convention for diffusion imaging.

This is one of several reasons I have ignored BIDS as much as possible.

Can you please enhance the documentation regarding the expected order of these stacked 4D files where possible? Thanks.

What documentation do you want to see and where do you want it to go?

I do not mean to be obtuse - as I started working with fsl, and this is the way all the fsl tools work, I've taken this format to be self-evident.
