#508 proposes a number of new suffixes meant for qMRI workflows. These suffixes all require multiple files, and in some cases some of those files may be equivalent to existing suffixes. For example, one file from a multi-parametric mapping (MPM) scheme may be the same as a T1w scan, and if the dataset curator knows this, they could identify it as such.

#508 also introduces the idea of symbolically linking dataset files to derivatives, in cases where the scanner automatically generates what would typically be considered a derivative (e.g., a T2map).

Would it be reasonable for the curator to symbolically link files within a dataset?

So, for example, we could have the two following:

sub-X/
    anat/
        sub-X_fa-1_mt-on_MPM.nii.gz ---
        sub-X_fa-1_mt-off_MPM.nii.gz  |
        sub-X_fa-2_mt-on_MPM.nii.gz   |  symbolic link
        sub-X_fa-2_mt-off_MPM.nii.gz  | 
        sub-X_T1w.nii.gz  <------------

Tagging @yarikoptic and @adswa to get Datalad-related thoughts, as well as @agahkarakuzu and @emdupre because they were involved in the initial conversation that spawned this issue.

This issue is related to #508 and #512.
