Null Pointer Exception when merging localizations

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Import the attached localisation file (csv format) into ThunderSTORM
2. Go to the "Merging" tab, click "Merge" (with default settings)

What is the expected output? What do you see instead?
The merging operation should be performed. Instead, a large number of 
successive popup appear with "Error! java.lang.NullPOinterException", with no 
choice but to force-quit ImageJ.

What version of the product are you using? On what operating system?
Latest daily build of ThunderSTORM, FIji wiht ImageJ 1.49m, Java 1.6.0_65 under 
OSX 10.10.1

Please provide any additional information below.
The same problem happens when trying to do fiducial-based drift correction (due 
to the presence of a merging step in the process I guess)

Fixed in revision 19e25ecc2343. You can update now to dev-2015-01-28-b1.

The problem was in uncertainty_z column. We do not have any method to calculate 
this. I've set this to calculate the merged uncertainty as mean value.
What method do you use for calculating this uncertainty? I could add this...

Best,
Martin

Great, thanks for the reactivity.

Unfortunatley, I don't have a simple way to calculate the Z uncertainty. I just 
multiply the XY uncertainty by a given factor (I chose 2), because using 2:1 
rugby balls in 3D is still closer to reality than using 1:1 soccer balls :)
