@tao I have just found out that the MAPILLARY_TOOLS_MAX_SEQUENCE_LENGTH environment variable/constant breaks the --cutoff_* options. Please drop it completely due to How Many Images per Sequence? - #6 by boris because otherwise it is just counter productive. Besides, setting MAPILLARY_TOOLS_MAX_SEQUENCE_LENGTH to a really large number does not work as expected either, so that it is broken anyway.
Or, if you really want to keep it for some other reason then please replace it with a --cutoff_count option to make its existence less obscure to users.
