THe most straightforward approach may be to save your traced labels as .mnc 
files within Display.

When you are in the save 'menu' you will note that you can either save your 
labels as a .tag or a .mnc.  I believe it is possible to reload your .tag files 
and then same them as .mnc ie:

    Display <file.mnc> -label labels.tag

file for alater analyze analysis.  (Display saves the label in the smallest 
possible minc volume it cna whilst maintaing the original resolution.

So use mincresample:

    mincresample -like infile.mnc label.mnc label_res.mnc

Then convert both to analyze:

    mnc2ana file.mnc file.hdr
    mnc2ana label.mnc label.hdr
