Dear Luke, Sorry interrupted.

Recently, I did simulation NEMA phantom of I131 used SIMIND.  
But what I reached is, there is problem with my projection data.

As comparing with example given from you (first picture), I attached the picture here. Also, I attached my input and output file (second picture) of mine.
