spam-filterPhiField: error: unrecognized arguments: -fr 1

Thank you for this great resource for DIC analysis. I would like to ask a question regarding filtering. I'm trying to apply to filter for displacement fields after 'spam-ldic' but I encountered this error message. Based on the tutorial, I think this is the parameter for a radius of filtering size. Could you please let me know why I cannot implement the filtering as in the tutorial? (https://ttk.gricad-pages.univ-grenoble-alpes.fr/spam/tutorials/tutorial-07-strain.html)

I appreciate your comments in advance.
