Hi to all,
I am working on a jython plugin that permits to track (manually) the spindles elongation in a z-stack timelapse experiment.
So I could have situations where spindle 1 is tracked until frame 10 and spindle 2 is track in frames 1,2,5,7.
I would like to set up the resulttable with automatically NaN or empty values (and not 0 like it is) so I could obtain easyly something like that:
sp1 3.2 12.3 3.4 5.6 7.7 0.5 ...
sp2 3.7 14.4            4.6       ...

without zero...is it possible?
or I've to scan my result table for zero and replace with "" or NaN?
thank you,
Emanuele
