[Clas12_verystrange] clas12root

[William Phelps]

Hello Michael,

It looks like the reader is looking for a bank entry/variable (vt) that does not exist. I suspect that the skim3_5038.hipo file was produced with an older version of the hipo bankdefs that did not have a vt (rf corrected vertex time).

The commit that added vt is here: https://github.com/JeffersonLab/clas12-offline-software/commit/0504417b2c78a6dcea652fc9309db7576114852e#diff-b009ca550664aa1e132f107476b2563f

Question to others: Is there a way to use clas12root with an older bank definition?

-Will
