I haven't worked with such files before, but they sound like tractography parcellated connectomes (parcels to parcels). If you take the ROIs used and make them into a .dlabel.nii file, you can fake a template parcels by parcels .pconn.nii file, and then replace its data with the tractography data.
To convert the ROIs file(s) to labels, use -*-reduce commands with INDEXMAX, and use -*-math to zero out places where there are no ROIs (-*-reduce with MAX would work to find these). You can then use -*-label-import commands, and -cifti-create-label to make the .dlabel.nii file (make sure your right and left labels aren't identical strings, add suffixes like V1_L or such). Faking a pconn will look a little silly, the way I'd do it is use -cifti-parcellate to parcellate the dlabel with itself (making a .plabel.nii), then -cifti-merge to repeat it to make a 2-column version, then feed that to -cifti-correlation to make the .pconn.nii (you'll get NaNs, but that isn't important, we just want the parcels by parcels mappings so we can import the matrix data into cifti). Finally, you'll need to get the data out of the .asc file into some format workbench understands. If it is simple enough, and it has the full square matrix in it, you may be able to use the -from-text option of -cifti-convert directly. If not, you'll probably need to use matlab/octave/etc to make the data into a simple square matrix and write it back out as gifti or simple text, and then use the relevant -cifti-convert option. HCP-Users is the place to ask questions like this (and has the most subscribers), the other lists are for other purposes.
