<div style="margin-top:0;margin-bottom:0;">Hi Ignacio,</div>
<div style="margin-top:0;margin-bottom:0;"><br>
</div>
<div style="margin-top:0;margin-bottom:0;">I tried reproducing that error message, but failed.</div>
<div style="margin-top:0;margin-bottom:0;"><br>
</div>
<div style="margin-top:0;margin-bottom:0;">In order to save the track local time (instead of the track length), as you described, I changed line 96 of source/digits_hits/src/GateTrackLengthActor.cc, replacing:<br>
</div>
<div style="margin-top:0;margin-bottom:0;"><br>
</div>
<div style="margin-top:0;margin-bottom:0;"> </div>
<div>pTrackLength->Fill( aTrack->GetTrackLength(),aTrack->GetWeight() );</div>
<div><br>
</div>
<div>... with:<br>
</div>
<div><br>
pTrackLength->Fill( aTrack->GetLocalTime(),aTrack->GetWeight() );</div>
<div><br>
</div>
<div>(I guess I should also change the TH1D title and label in the Construct method, to say "track local time instead of track length", and similar text changes in the messenger class, but that's all cosmetics for now.)<br>
</div>
<div><br>
</div>
<div>In order to find out which method to use ("GetLocalTime()" on "aTrack") I checked the G4Track.hh header file in the geant4 source code, but I could also have found it online in the "doxygen" reference manual, e.g.</div>
<div><a href="https://geant4.kek.jp/Reference/10.05.p01/classG4Track.html" target="_blank" rel="noopener noreferrer" id="LPlnk926169" previewremoved="true"><span id="LPlnk926169">https://geant4.kek.jp/Reference/10.05.p01/classG4Track.html</span></a></div>
<div><br>
</div>
<div>After this simple modification, GATE compiles just file. Since you do get an compiler error, about G4VHit, your code is probably quite different. What did you try?</div>
<div><br>
</div>
<div>HTH,</div>
<div>David</div>

<div style="direction: ltr; text-align: left;" dir="ltr">I attempted to replicate the same setup from GateTrackLengthActor since the docs refers to it as an example. I am trying to save the local flight time of photons, pixel ID of detector and run ID (I know
the standard root output has this information but I would like to save the storage). As a first attempt for a new actor, I only tried saving the track local time but when I try running make I get the error “‘const class G4VHit’ has no member named ‘GetTrackLocalTime’”. </div>

<div dir="ltr">Hello Gate users,
<div><br>
</div>
<div>I was wondering if there are better instructions for developing new actors? I have looked at <a href="http://wiki.opengatecollaboration.org/index.php/GateActor" data-ogsc="" style="">http://wiki.opengatecollaboration.org/index.php/GateActor</a> but I am
having trouble with developing the 4 required files (actor.cc, actor.hh, actorMessenger.cc, actorMessenger.hh). </div>
<div><br>
</div>
<div>Basically I would like to create an actor that is a mini version of the root output file. I don't need the entire output of root; I only require certain leaves from the Hits tree to save memory storage. </div>
<div><br>
</div>
<div>Thank you for your time.</div>
