Segmentation fault running TRestAnalysisPlot

[Cogollos]

REST version : v2.2.14
REST commit : cfa2d241

I am trying to run a simple script for obtaining three different histograms given the same input file but setting different cuts for each plot. The program should display them, and save them automatically.
The command line I run is:
restManager --c restPlotIsotopeSAFEC_HistoEnergy.rml --f Co60_TrackAnalysis.root

When I run the script I can briefly see two of the three histograms, then I get a segmentation fault and the program crashes. It generates two of the three files, but after checking them I can see they are empty.

The complete output is:

Segmentation fault

Do you have any ideas about where could the origin of the problem be?

I attach the following files:

• restPlotIsotopeSAFEC_HistoEnergy.rml ->Configuration file for the plots
• Co60_TrackAnalysis.root → Input file for the plots (Too big for uploading it to the forum): CERNBox
• BG_Spectrum_Co60_CapBottomCentre_CutsOFF.root → First output file generated by the script
• BG_Spectrum_Co60_CapBottomCentre_TrackCutON.root → Second output file generated by the script
  restPlotIsotopeSAFEC_HistoEnergy.rml (2.9 KB)
  BG_Spectrum_Co60_CapBottomCentre_TrackCutON.root (8.3 KB)
  BG_Spectrum_Co60_CapBottomCentre_CutsOFF.root (8.3 KB)

Hi,

looking at your rml file I found the plot names you are using are the same for each plot. This is the reason why you get a seg.fault.

I have added few lines at TRestAnalysisPlot in the latest commit to check that those names are not the same, and output an error in case they are.

As you can see in the following image

Then, for the plot generation it seems there are still some issues, I guess that’s a kind of problem of compatibility with the new TRestAnalysisPlot version. I find repeated plots in smaller size inside the canvas.

Maybe @nkx might bring some light on that.

Check out this post to follow recent changes to TRestAnalysisPlot

Launching restManager in batch mode

Looks like in 2.1.7 we were setting the input arguments for TRint to enable batch mode. I have updated the code and implemented this feature in similar way

On the other hand you must know that it is possible to generate the root or pdf files without popping up the canvas on screen, just adding --batch to the restManager command.

See for example

Hi Javier,
Changing the names I still get a segmentation fault. I even get this error with a similar script but only one plot. In general, if I have a script with N plots I can see how REST generates N-1 plots and then crashes, but the output files it generates are empty.

Could you switch to the ROOT-REST-Garfield versions I define in my .bashrc in sultan? Do you still have this problem?

[jgalan]

I realised that if I remove save="filename.root"/> option from <plot it will not draw the smaller histograms.

[Cogollos]

Now it seems to be working properly. Even though I still get a seg.fault after the script ends

I realised that if I remove save="filename.root"/> option from <plot it will not draw the smaller histograms.

Yes, I was checking that also, seems like I’m re-ploting everything.

I don’t know what the problem with the version can be, but for future reference, I was using root-6.10.06 and REST v2.2.14 as compiled on sultan at /programas.

[jgalan]

@Cogollos

I still get a seg.fault after the script ends

That seg.fault line is coming from Garfield libraries and it is warmless. Still annoying. I have compiled /programas/REST/testing/ without Garfield and now it does not appear.

[jgalan]

In order to use /programas/REST/v2.2.14/ you need to use ROOT6.16.00, many problems come from there.

export GARFIELD_HOME=/programas/garfield/garfield6/
export HEED_DATABASE=$GARFIELD_HOME/Heed/heed++/database
export LD_LIBRARY_PATH=$GARFIELD_HOME/lib:$LD_LIBRARY_PATH

## REST v2.2.14 was compiled linking to 6.16.00
source /programas/root/root-6.16.00/install/bin/thisroot.sh
source /programas/REST/v2.2.14/thisREST.sh

[jgalan]

@jgalan

I find repeated plots in smaller size inside the canvas.

This problem has been fixed in the last commit.

[nkx]

Hi, sorry for the late response. Is the problem solved?

[jgalan]

I believe both problems are solved, the segmentation fault related to same plot name, and the mini-plot appearing when calling SavePlotToPDF.

Still, there is a Segmentation Fault line appearing at the end of the execution (which seems to be harmless but annoying). This segmentation fault line output seems connected to Garfield. It only appears when we linked REST libraries to Garfield.

[Cogollos]

There was another segmentation fault that was solved using ROOT6.16 instead of ROOT6.10.

[jgalan]

@Cogollos

was solved using ROOT6.16

Ok, the reason behind it is because the REST you were using had been compiled/linked to ROOT 6.16.
