Hi Tom,
Just a few days ago I helped another person to write a simple script
that does something that can be of use in your case. Basically, you
need to prepare a file that contains frames of your "trajectory", and
for each frame it has the same number of "particles" - 300 in your
case. Then, for those particles (cells) that do not exist at a given
frame yet, you just set their coordinates to something very far away,
so that when you look closely at your embryo those cells cannot be
seen. This is a simple hack that can work well for visualization and
for many types of analysis.
Maybe someone on the list knows a better solution...
If you are interested, please let me know, I will send you the script
then and tell how to use it.
Best,
Anton.
