[Clas12_software] Coatjava 2.0 reconstruction crash

[Brian Eng]

Whitney,

Here's the first place I'd look (requires a JLAB CUE login): https://clas12svn.jlab.org/repos/clas12/

There should be subdirectories for the various software packages. I'm not sure if that is where everything is officially stored or not though.

Should at least get you started until someone else has a more definitive answer.

Hope that helps.

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.
