<div>Hi gate users!</div>
<div>I installed the gate3.1.2 on my computer successfully and ran ncat phantom with 128*128 array and 128 slices with no error.</div>
<div>problem arises when i use the ncat voxelized source(with 75 bq activity in each voxel of heart and others=0). GATE show ncat voxel phantom truely but in voxel source, the voxel number yhat gate recognized is 0 and then the total activity is 0.</div>
<div> </div>
<div>(i use voxelized source instead of voxelized ohantom in my macro and gate realized it successfully and show me a heart in opengl viewer)</div>
<div> </div>
<div>what is it's problem to run the ncat voxel source and why it's voxel number is zero?</div>
<div>help me to overcome this problem.</div>
<div> </div>
<div>thank you.</div>
