Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
I would appreciate if someone could clarify my ideas about a Geant4 feature called "latch".
My understanding is that latch is used in a phase space file to keep track of a particle origin.
Someone states it is used to record the particle last interaction before getting at the phase space surface.
Anyway, I would need to generate an output phase space file which stores ONLY the histories whose LAST interaction, before reaching the phase space surface, occurred in a selected component. I don't care about what happened below the phase space surface. Is this feasible through the latch feature or any other way ?
Many thanks. Mauede
