Hi

There's no such thing as a reconstructed sinogram. Did you display the
sinograms produced by GATE (e.g. with STIR, but if that doesn't work
with other software that can read ECAT7 sinograms?) On the other hand, I
have no clue how STIR could figure out that this ECAT7 file corresponds
to a Discovery (you'll have to do some tricks by hand as mentioned
before on this list). That shouldn't stop it display it ok of course.
But reconstructing is another matter.
