[Castor-users] CT reconstruction error

[Konstantinos P. Chatzipapas]

Dear Hadi,

There are probably many things that could go wrong with your 
application. For example you say that you combined and converted them. 
How exactly? How did you assigned the pixels ID? How does your geometry 
file looks like?

Best,
Konstantinos
