TrackMate: can not import FastLAPTrackerFactory

[Greg]

Hi,

I am stuck because I can not import the FastLAPTrackerFactory within jython. According to this tutorial

http://fiji.sc/Scripting_TrackMate

All I need is to

from fiji.plugin.trackmate.tracking import FastLAPTrackerFactory

but I get a classical import error:

ImportError: cannot import name FastLAPTrackerFactory

When in inspect the module via

print dir(fiji.plugin.trackmate.tracking)

the output is

['LAPUtils', '__name__'] .

So there is almost nothing there ?!

I am running the latest updated Fiji 1.49p on Mac OS 10.10.

Any help appreciated !

Greets,
Greg

Looks like that class changed packages [1].

You could try:

  from fiji.plugin.trackmate.tracking.oldlap import FastLAPTrackerFactory

But note the package is now called "oldlap" which implies there is a
newer/better/shinier API now. Hopefully Jean-Yves can clarify that further.

Curtis

Hi Curtis,

ya I expected some class reorganization..so thx, I will go with your advice for now! As long as the TrackMate Scripting Tutorial is not updated either, I bet I could not do much with the 'newer' API anyways..

Best,
Greg

Hi all
I fixed the scripts on the Wiki pages.

Curtis is right: since v2.7.x TrackMate ships a full rewrite of the LAP trackers, and they have been moved and renamed. I also uploaded the 4 scripts to github.
Best
