[Gate-users] projection file problem (gate.sin file) of SPECT simulation

[sebnem erturk]

Dear All,

After my SPECT simulations, I obtained gate.sin file, but I got just a small
point in the middle of pixel when I opened the binary file with XMEDCON.

I would  like to reconstruct this projection file, but still I could not get
any satisfactory projection file to reconstruct.

I do not know what is the problem ; my used activity or my macro???

Do you have any idea?  I also attached my macro file.

Thank you for your help in advance.

The macro related with my source and projeciton part also informed below:
