Hi Manasi,
I checked and vmticpregistration version 0.9 (I'm looking at the precompiled
binary) does include -iterations.
In any case, you should be fine just setting a small -maxmeandistance,
iterations should be set automatically in an appropriate way, so you can just
skip the option for now.
Best regards
Luca
