Option names conflict in OpenIMAJ

[Anonymous]

Hello,

I just found there are options names conflict in OpenIMAJ when used
ImageTerrierTools basic indexer to make an index. I specified the -ft
option to choose ASIFT or ASIFTENRICHED feature extraction mode. I got the
error message:

I traced the code in OpenIMAJ and found that either ASIFT or ASIFTENRICHED
use -nt as an option name for --n-tilts. And ClusterType class also uses
-nt for --number-of-trees option. I think it is the reason to cause the
problem. Can it be fixed by change one of the aliases name to avoid the
conflict? Thanks.

Good catch. I've removed the -nt alias from the ASIFT/ASIFTENRICHED modes in rev #2568, so you'll now have to use --n-tilts to specify the number of tilts.
