so if dicom import produced same filenames (for some reason- does not happen with our own demodata) across different image directories, it stops processing and warns the user to rename their files (in a way that they see appropriate) and then continue processing

I would suggest just making the output filenames unique using matlab.lang.makeuniquestrings, especially since it seems that this problem will keep happening with the new Siemens DICOMs. That function gives a second output which can be used to let the user know which files have been changed.

I shortly considered doing that too but last night did not remember that makeuniquestrings was available from R2014a (thought it was availabe more in later versions) as noted in the link you shared below, then I might modify the implementation using makeuniquestrings
