Bug #13820

Updated by Gianluca Petrillo over 4 years ago

Dear LArSoft Experts,

I am having a strange problem with event display. If I reconstruct one event, look at it in event display and hit reload button, the event display would exit.

Here is how to reproduce this problem on a dunegpvm machine.
<pre>source source /grid/fermiapp/products/dune/setup_dune.sh
setup dunetpc v06_05_00 -q e10:prof
lar -c standard_reco_dune10kt_1x2x6.fcl /pnfs/dune/scratch/dunepro/v06_04_01/detsim/prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6/13289364_0/prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6_7_20160826T215719_gen_6b914fe0-09c3-469e-b1f0-056dad368a1b_g4_detsim.root -n 1
lar -c evd_dunefd.fcl prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6_7_20160826T215719_gen_6b914fe0-09c3-469e-b1f0-056dad368a1b_g4_detsim_reco.root</pre> prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6_7_20160826T215719_gen_6b914fe0-09c3-469e-b1f0-056dad368a1b_g4_detsim_reco.root
click Reload, event display will exit.

However, if I run event display on the file with all reconstructed events (from production):
<pre>lar lar -c evd_dunefd.fcl /pnfs/dune/scratch/dunepro/v06_04_01/reco/prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6/10111991_0/prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6_44_20160826T215741_gen_d40d2d5c-caa1-4a3f-b716-4e62843057dd_g4_detsim_reco.root</pre> /pnfs/dune/scratch/dunepro/v06_04_01/reco/prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6/10111991_0/prod_muminus_0.1-5.0GeV_isotropic_dune10kt_1x2x6_44_20160826T215741_gen_d40d2d5c-caa1-4a3f-b716-4e62843057dd_g4_detsim_reco.root
Clicking Reload does not exit.

I am having the same problem with argoneut as well. This is annoying because every time I change event display configuration (e.g. track module label), the display would refresh and quite. I suspect this is an art problem and I started to seeing this problem since moving to art2 (larsoft v06).

Thanks,
Tingjun
