[Rivet] issue with mkhtml complaining about ReadError

[Raghav Kunnawalkam Elayavalli]

hmm interesting, its only showing the one file that im loading

[rkunnawa at lxplus0031 YpJet]$ pwd
/afs/cern.ch/work/r/rkunnawa/JEWEL/PLOTS/YpJet<http://cern.ch/work/r/rkunnawa/JEWEL/PLOTS/YpJet>
[rkunnawa at lxplus0031 YpJet]$ rivet-mkhtml --font=helvetica --outputdir=plots_Official_YpJet --mc-errs mc.yoda:'$JEWEL+PYTHIA$ PbPb'

Output from rivet-cmphistos

Crash in rivet-cmphistos code =  1  exiting

i wonder why its not showing the reference data file sitting here:
/afs/cern.ch/work/r/rkunnawa/JEWEL/ANALYSIS<http://cern.ch/work/r/rkunnawa/JEWEL/ANALYSIS>

the aforementioned path is in my RIVET_DATA_PATH and also RIVET_ANALYSIS_PATH so im not sure what file its loading now.
I even moved them to the same location and it still complained.
then i added the export statements to point both to the same location in lxplus and still the same error.

Cheers

Probably loading *something* with a matching name. The line being complained about *does* look like part of a YODA file... or maybe a .dat file that accidentally got named .yoda.

I'd like to know the answer -- could you try adding a "print infile" line to rivet-cmphistos just above the "analysisobjects = yoda.read(infile, ..." line on line ~110, and run again without the double-colon path forcing?

Thanks (and glad we've got a workaround),
Andy

Ok instead of waiting for it to finish, i tested it locally (yoda v1.5.9) with adding the data and analysis path definitions you mentioned and it worked. Does this mean that its loading another yoda file or something somewhere with a matching name etc?

If using YODA 1.6.x you will need to build Rivet + analyses using the C++11 compiler mode. Not *hard* but an extra technicality, and YODA 1.5.9 should be fine so that's what I recommend until the Rivet 2.5.x series.

Do you actually know what file is producing this parser error? It's very strange. And there are line breaks in the "line" written out in the error message, which shouldn't be possible... is that just an email formatting thing?

I think that rivet-cmphistos will try to parse *all* the .yoda files found in Rivet's ref data collection, in case any of them match your MC histogram path. If both your MC and reference .yoda file are in the current directory, try setting
export RIVET_DATA_PATH=$PWD::
and/or
export RIVET_ANALYSIS_PATH=$PWD::
and run rivet-cmphistos again.
(NB. the double-colon on the end matters, to stop fallback to the default Rivet data search paths)

Andy

Hi Raghav,

I don't have this problem with yoda v1.6.0. Do you mind reinstalling the
latest version of yoda and seeing if it works? I'll let Andy chime in,
but I don't think there are big differences between your version of yoda
and mine, so performing a clean install of 1.5.9 may also do the trick.

   Hi Chris,

   I currently have v1.5.9 installed. Ive attached a file which has the
   first histogram d01-x01-y01 in both the analysis.yoda (data) and
   mc.yoda (what i get after running rivet -a analysis test.hepmc)
   Please let me know if you need anything else to debug the issue.
   Cheers

   Hi Raghav,

   It looks like the .yoda file(s) you have don't conform to the file
   format. Can you tell us which version of yoda you are using and
   give us an example file?

   Cheers,

   Chris

       Hi Rivet Experts,

       I have an analysis with its corresponding yoda file with the
       data points for reference
       say analysis.cc<http://analysis.cc> <http://analysis.cc/> and analysis.yoda. Now i
       compile it and run it with my MC and when i do
       rivet-mkhtml mc.yoda  , I get a weird error

       I dont have this particular line it points to in both my
       mc.yoda and analysis.yoda!
       So i dont know what might cause this. any ideas?

       thanks!
