[MINC-users] Co-registration metric (minctracc)

[Paul GRAVEL]

Dear All,

Hope all is well!

Is there a metric (or metrics) to test the goodness of co-registration 
with minctracc (would that be comparing the Initial objective function 
val vs. Final objective function value)?

The reason for this question is that I am running a script that does 2 
passes of a PET to PET co-registration, but sometimes the second pass 
messes things up, especially when the first pass looks good.
Thus I would like to use this metric to automatically check whether or not 
the second pass should be run at all.
Of course, I would still visually inspect the end results ;-)!

Thanks!

Paul
