[Clas12_software] Coatjava 2.0 reconstruction crash

[Armstrong, Whitney R.]

Thanks David.

Since this is a bug, do you (or anybody else) know where I can checkout the latest source code for coatjava? This way I could maybe find the bug, fix it, push the fix upstream, and maybe learn something in the process.

I seem to only be able to find jar files ...

Cheers,
Whitney

This is an inconsistency between the latest magfield package and the reconstruction you are using. The lastest magfield removed methods to invert the field and to test for inversion, instead (to be more consistent and simplify usage) it uses only a setScale method, which can also invert, e.g. by setting th scale factor to -1.

I know that the reconstruction software was modified to comply with the new magfield interface--but somehow some old reconstruction code is still around.

Hope that helps,
dph

Hello Everyone,

I switched over to coatjava 2.0 and the following error occurs when reconstructing simulation.

The version 1.0 runs without crashing.

Cheers,
Whitney
