Event Display known problems


Date/version
Known problem/solution
03/12/2004
5.3.1
 If you don't see cot/svx/smx information in the evd, read how to decompress data .
It will be default in the next release.
06/28/2002
4.5.0int4
up to 4.6.0int4

CDF doesn't link to the graphics system by default in order to minimize root dependencies for the purposes of the EDM and DH systems.

To remain consistent the default assumption of the framework has been changed to assume batch mode and tell root to NOT initialize the graphics subsystems.

This was done in 4.5.0int4, since then evd doesn't bring up any windows. To initialize the ROOT graphics run evd.exe/mon.exe as:

evd.exe your_tcl_file -g
mon.exe your_tcl_file -g

It's fixed in the older versions.

4.4.0
 EventDisplay executable crashes.
The reason is not relevant to evd itself. To fix it add these lines to your tcl file: 
talk GeometryManager
  SiliconGeometryMenu
    AlignmentSource set "none"
  exit
exit
If you run evd as evd /file name/ edit /tmp/evd.tcl.{$USER} and run evd as
evd.exe /tmp/evd.tcl.{$USER}

4.2.0
4.2.0int1 		EventDisplay crashes when one tries to open TLegoFrame based windows:
TLegoDisplay, TPlugDisplay, TCesDisplay.

If you need these displays, type this line from the ROOT prompt:
TEdCut* etcut = new TEdCut("TEdTower::Pt",0.0,1000.0)

11/04/2001
< 4.1.0int3 		Add these lines to your tcl file to skip empty run records: 
  talk DHInput:
     setInput inorder
  exit
10/15/2001
4.0.0int3
4.0.0int4
4.0.0int5
4.1.0 		Add this lines to your tcl file to avoid PuffModule related crashes: 
talk PuffModule
  dontPuff add CdfJetColl
exit
thanks to M.Herndon for this hint.

4.0.0

Turgun Nigmanov reported about problems with Event Display v4.0.0. It crashes when reading some files.
The problem is due to the PuffModule.

To solve this problem disable this module in your tcl file:

mod disable PuffModule

If you are running evd as

evd [file_name]

you should edit /tmp/evd.tcl.{$USER} and run evd as

evd.exe /tmp/evd.tcl.{$USER}.

3.15.0int2
3.15.0int3

Pasha Murat reported about problem with running EventDisplay 3.15.0int2 and 3.15.0int3. When you request to show COT display(or any other display), it pops up an empty window.

The problem is in the MyronFilterModule. In the development this bug is fixed, and it is fixed in the 3.16.0.

So, what everybody should do(I've done - it works) to get working Event Display in the 3.15.0int2/int3 - just to disable MyronFilterModule: 

             root [3] .q
             AC++> mod disable MyronFilterModule
             AC++> root

If you need Myron Mode Flag feature(look at the EvD homepage, e.g. how to use it), use the development version.


Howto section is updated as often as possible, so check it out sometimes.  
Warnings!


  • don't use the development version (taken from the head of the repository) unless you really need it
  • Event Display is constantly updated, do please be attentive: there could be new parameters in the talk-to's, new options.
    To speed up EventDisplay:
  • don't open several windows if you need the only one
  • switch off all the information you don't need
