sPHENIX tracking discussion

Hi Christof,

use the root5 implementation. This uses the old genfit (it has to - the new ones require root6) and I kept it alive exactly for this reason.

Hi Jin, Chris and Tony

I had a look at the reason for the low tracking efficiency we see currently (~65% in mb + pileup). 

Almost all the tracks we miss currently are lost in the seed fitting stage by genfit.

This is getting a bit annoying. It looks like we need some fix for this soon. 

With the old version of GenFit we always had tracking efficiency ~= seeding efficiency.

Just to verify, how can I compile the code with the old GenFit version?

Cheers
