[Gate-users] Corrigendum: My mistake in pprevious messaga: Problem running GATE and ROOT with regularMatrix argument

[Javier Ors Anía]

I can't tell you a precise answer for your displacement problems, but I
can tell you to be very careful with rotations and translations
involving regularMatrix volumes.

I see in you code that you apply a rotation to you volume, and I can
tell you that there is a bug in the code that prevents rotations and
translations being applied at all to regularMatrix volumes. Now I'm not
sure about whether this bug also affects compressedMatrix volumes, but I
think that this is not the case. So this is probably the origin of the
differences you see between using one or another type of volume. Make a
try with a big translation in one axis and you'll see what I say.

I reported this problem about one month ago and also sent a patch that
I'm using right now for it, but nobody answered, this is the link to my
message in the list archives:
