TFile creation and TTree

When the filename base IO was added, it seems that TFile creation was moved from 
ROMEEventLoop::DAQInit to ROMEEventLoop:DAQEndOfRun.

So ROME makes TTrees without outputfile.

This is dangerous when a TTree becomes huge.
It can consume large amount of memory.

Your right. I have changed it back.

Recently the place to call ROMEEventLoop:Update was moved.
Probably because of this, in MIDAS online mode, event number is always incremented even when DAQ is not running.

When I run ROME analyzer in online MIDAS mode.
It stopps with making core (segmentation fault).

It seems it makes core after "return" in main.cpp, namely finishing all code.

When I comment out following line in ROMEAnalyzer.cpp, it works propery.
tnet->StartServer(gROME->GetApplication(),gROME->GetPortNumber());

Probably it is relating to ROMENetServer or thread for this.

I investigated the problem.

On my machine (Scientific Linux 4.2, gcc3.3.2, glibc2.3.2, ROOT5.08.00), following simple program reproduced the problem.
There was no probelm with ROOT version4.
Is it bug of ROOT ?

When I put -lpthread at the last. This problem stopped.
Actually without this option, my analyzer workes.
I guess -lpthread is not necessary.

I will check more and if not necessary, I will remove -lpthread.

--- Makefile ---

rootlibs := $(shell $(ROOTSYS)/bin/root-config --libs)
rootcflags := $(shell  $(ROOTSYS)/bin/root-config --cflags)

test: main.cpp
	g++ $(rootcflags) -o $@ $< -lpthread $(rootlibs) -lThread

#include <Riostream.h>
#include <TThread.h>

void* TestLoop(void *arg)
{
   return NULL;
}

int main(int argc, char *argv[])
{
   TThread *thread = new TThread("TestLoop", TestLoop);

   cout<<"OK"<<endl;
   return 0;

gAnalyzer->GetEventID() fails if EventID>127-48

This bug happened when reading a .MID file containing events with event_id=99.
The ReadMidas task is not able to read the event because it is not recognized.
This event_id, when recovered with GetEventID() method was transformed to a negative value. This probably happened because there is a +48 addition at some place (in SetEventID) and a -48 on GetEventID. This casuses the unsigned char to be recovered as a signed number (lots of FFFF in front of it).

Furthermore it is not writtenanywhere that EventID<0xFF.

I could solve the problem
1) by setting EventID = 16, for instance
2) by modifying ROMEAnalyzer.h as follows
// Event ID
Int_t GetEventID() { return (fEventID-48)&0xFF; }
char GetEventIDChar() { return (fEventID)&0xFF; }

Unable to run rome analyzer from crontab

I would like to use a bash script run from cron to analyze new midas event files automatically. Below is an abbreviated example script to test the way ROOT and ROME handle true batch mode

#! /bin/bash

BASEDIR=/data/0/PostRunQA		# Base directory for output files
ROMEDIR=${BASEDIR}/dance-rome		# Location of danceanalyzer

NRUN=7581
ROMECFG="romeConfig_Continuous.xml";

# Set PATH and LD_LIBRARY_PATH for correct versions of ...
# This also sets up the *SYS variables
source /opt/wnr/new/bin/newVersion --new root rome wnr

cd ${ROMEDIR};

# Check that ROOT works correctly
echo " Running ROOT batch mode test ";
root -b -q ../jmodScript.C

# Check that ROME works correctly
echo " Running danceanalyzer batch mode test ";
./danceanalyzer.exe -b -ns -q -i ${ROMECFG} -r ${NRUN}

The results for the ROOT section are the same when the script is run from the command line (full interactive environment) or when using at or crontab (non-interactive).

We are using the following setup:

I can provide additional information if needed.

Unable to run rome analyzer from crontab

(sorry for top-reply- I am trying to avoid elcode garbling my answer)

In the past, I have seen problems like yours, there are at least two issues:

1) "non interactive" ROOT running from cron or some other incomplete user
environment (no DISPLAY, no tty, no user)- a hello world script runs, but large
app does not, because some silly class somewhere requires an X11 connection. I
once had to fake it by running Xvnc and telling the cron jobs to use it as a
DISPLAY. I know ROOT now have a "dummy" graphics module exactly for this
purpose. I do not know how to activate it from the Rome environement, but I am
sure it is documented somewhere on the ROOT web site.

2) some programs coming from the MIDAS family assume existance of a keyboard and
display. Sometimes they can be faked by using "program < /dev/null", sometimes
not, I do not know what Rome does.

K.O.

Problems with programming tabs when using TGraph

Dear Colleagues,
 
I have been using the ROME framework and have succesfully implemented a program 
to run on MIDAS input and plot histograms.

Not satisfied with the default settings of the Canvas, pads and text sizes etc I 
consulted Ryu who kindly showed me how to implement the event and init and update 
methods in the Tabs to bring the display closer to what I needed.

This has worked fine with histograms. However not with TGraphs:

I noticed that if I implemented the plotting of the TGraphs in the tab class then 
after setting points in the TGraph in the Fill tasks the Tab classes plot was 
empty -> is there something peculiar about TGraph ? Any tips would be great !

many thanks
Farrukh Azfar

Problems with programming tabs when using TGraph

Dear Farrukh

I presume you implemented your tab which draws the graph.
Which option do you use for Draw function of the graph ?
I am afraid you might forget to add 'A' in the option.
For example, you need to use 'A' like,

  graph->Draw("APL");

Best regards,

Ryu

Saving canvas as pdf via a button one vs many pads

Dear Colleagues 

we have implemented in one of our tabs a button to call a function which saves a 
canvas to a pdf file with a time date stamp.

1) This works fine when there is only one histogram on the canvas and this code 
is MIDTBCTab.cpp (attached)

2) When the canvas is divided up into a 5x11 pads with 55 histograms and 
we want to save the _whole_ canvas with the whole picture (_not_ any individual 
pads) the code crashes  and no file is generated - the tab code is MIDTRCTab.cpp
and this is also attached 

I am wondering what is going on - is there anything obviously wrong ?

many thanks 

Farrukh

TMTT3.cpp -offset in index of the pads

Hi Ryu,

I have been working with your /rome/examples/argus/menu/tab/TMTT3.cpp cpde and
I've run your menu.xml with a dummy midas file run0001.mid in the offline mode,
and in the AREGUS monitor, when I click on "open and save" menu, it shows
options for 4 pads. But if you click on the first pad, it is empty, if you click
on pad 2, it will have hist1, pad3 has hist2, and pad4 is hist3 and there is no
hist4.
So there is an offset of 1. 

In case of my 55 histograms I am getting the same error. I am getting only upto
hist54 (my first hist is called hist00).

Could you please help me with this issue?

Saving canvas as pdf via a button one vs many pads

Dear Farrukh

I tried your code, but the problem was not reproduced.
I can save the canvas as attached without crash.

Only the difference from your code is the histograms.
Since I don't have your task I took and draw 'ADC' histograms from 'FillHistogram' task.
No other changes were made from your code.
I edited .h file of the tab from the automatically generated ones.

Ryu

Saving canvas as pdf via a button one vs many pads

Dear Ryu,

thanks very much for trying this out. Perhaps Sudeshna can verify that the problem is still 
there in her code or if its fixed ?

Running ROME remotely

Hi Ryu,

After following your instructions to run ROME remotely, using run mode 3 on the
client machine, and mode 0 on the server machine, we can see ARGUS display
appearing on the client machine.
But that does not work if we have the <ARGUS> block for tabbing in the user xml
file. I see a bunch of error messages and then ROME crashes on the client machine.
There might be some conflict with using ARGUS and using run mode 3?

If I take off the <ARGUS> tab block and write my own src/tabs/tab codes, then on
my client machine, using run mode 3 works, the display appears with histograms
without a crash.

Any thought on this issue will be much appreciated.

Thanks,
Sudeshna

Running ROME remotely

Dear Sudeshna

I modified ROME to try to fix problems related <ARGUS> block histograms in run-mode 3.
Could you please pull ROME and use the 'develop' branch ?
(You can switch branches with "git checkout develop' command)

There is an example, examples/argus/histogram.
I tested with the example and it works.

'romeproject' in the directory works as a server.

What you need to use the example for the test is,
0) 'make' in $ROMESYS
1) Build and compile both  examples/argus/histogram and  examples/argus/histogram/romeproject
2) Start analyzer in romeproject with using romeConfig.xml
3) Start monitor with using argusConfig.xml

In the second tab, you must see an <ARGUS> block histogram updated periodically.

Ryu

Error with maximum number of tabs in Argus section

Hi Ryu,

I am trying to use <Argus> for tabbing like this:
  <Argus>
          <Tab>
            <TabName>Tab1</TabName>
            <ObjectArrayIndex>0</ObjectArrayIndex>

            <Index>0</Index>
 </Tab>
   <Tab>
            <TabName>Tab1</TabName>
            <ObjectArrayIndex>1</ObjectArrayIndex>
            <Index>1</Index>
          </Tab>
   <Tab>
            <TabName>Tab1</TabName>
            <ObjectArrayIndex>2</ObjectArrayIndex>

            <Index>2</Index>
          </Tab>




And I need to add 18 tabs with each tab having three pads.
Now I when ever I cross Tab6 with three pads on it, it gives me this error:

[sganguly@g2be1 rometest]$ /home/sganguly/dqm/rome/bin/romebuilder.exe -i
midas.xml -midas
Maximal number of Tabs in the Argus section of Histogram 'h1_wf' reached : 20 !

I have noticed that currently I can define 6 tabs and 5 pads on each tab maximum.

Could you please help me with this?

Thanks a lot!
