Hi Leonid and Xinjie,
<div class=""><br class="">
<div class="">This appears to be a STIR question more than a GATE <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class="">question</span>. STIR can unlist SPECT data but not from the ROOT format as the ROOT file configuration is different to
the PET data. </div>
<div class=""><br class="">
</div>
<div class=""><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class="">Leonid</span>, I suggest sending a message to the STIR users list (see:
<a href="http://stir.sourceforge.net/" class="">http://stir.sourceforge.net/</a>) with some details of your ROOT file and GATE simulation configuration, maybe someone in the community has written the code to do this already or you may receive more technical
help.</div>
<div class=""><br class="">

<div class="">Kind Regards,<br class="">
