[Rtk-users] geometryReader->GetOutputObject() number of input files

[Marc Vila Oliva]

Hello Laura, 

I was checking your geometry file (geometry.xml) and it seems fine for
me, according to your prior description. 

15 projections along 360°

You have the first projections at 0°, then the 2nd at 24° and so on. 

What were you expecting?

Cheers, 
Marc
