[Gate-users] GATE output root file conversion to projection filr for STIR using Bin_GATE_v1.0.c

[Satyajit Ghosh]

Dear All,

                There is some issue with the DLS parameters that I have
defined earlier. After correction, now it produces required projection
outputs for STIR.

Thanks & Regards
