??: Re: [Gate-users] 3-D image reconstruction using STIR from GATE Results

[Thielemans, Kris]

Hi Claude
 
I didn't know that iv_volumetool could display sinograms. Thanks for the info!
 
So, I guess we either see a problem with ifheaders_for_ecat7 or with the Guifen's local GATE installation. Guifen, maybe you could drop your ECAT7 file at ftp.hammersmithimanet.com (cd /in/kris) and let me know. I can have a quick look at it here.

No, I did not use ifheaders_for_ecat7. I used an ecat7 dedicated
software developped by the University of Louvain-la-Neuve, Belgium,
(iv_volumetool) to display directly the ecat7 sinogram file generated by
GATE. As far as GATE is concerned, there is no problem with your macro
and the ecat7 sinogram file is correct.
