Yes, it can be done easily by nesting the tab definition in your definition XML file.
An example is $ROMESYS/examples/argus/tabs

Dear Joe

There is a working example for the online access to midas.

Please see,
https://bitbucket.org/muegamma/rome3/wiki/Midas
The example is $ROMESYS/examples/midas.
There is a README file in the directory.
The example works with an example experiment in MIDAS package so you can try.
If you look at ADC2 tab, the histograms should be updated when DAQ is running.

The "Trigger" events are polled in the MIDAS frontend, and "Scaler" data are taken periodically.
So I guess the "Scaler" corresponds to your INPT and "Trigger" corresponds to your other event types.

You may compare the examples and your analyzer/frontend for finding the cause of your problem.

I wanted to add two different TGraphs (Corresponding to two calorimeters) into
the same pad.
So in the xml file I did:
<Graph>
  <GraphName>MyGraph</GraphName>
  <GraphFolderName>mygraphs</GraphFolderName>
  <GraphType>TGraph</GraphType>
<GraphArraySize>2</GraphArraySize>
  <GraphXLabel>Event no.</GraphXLabel>
  <GraphYLabel>Island no.</GraphYLabel>
  <GraphXmin>0</GraphXmin>
  <GraphXmax>10000</GraphXmax>
  <GraphYmin>0</GraphYmin>
  <GraphYmax>100000</GraphYmax>
 <Argus>
<Tab>
      <TabName>SummaryFCBank</TabName>
    <ObjectArrayIndex>0-1</ObjectArrayIndex>
      <Index>1</Index>
 <DrawSamePad>true</DrawSamePad>
    </Tab>
  </Argus>
</Graph>


And in src/tasks:
in the HGUITFillHisto.cpp code I did:
 for(int icalo=1; icalo<3; icalo++)   [For each calorimeter there is one bank, and one n_islands value from that
bank per event.]                        
    {
GetMyGraphAt(icalo-1)->SetPoint(gAnalyzer->GetCurrentEventNumber(),gAnalyzer->GetCurrentEventNumber(),n_islands);

 GetMyGraphAt(0)->SetMarkerColor(2); 

 GetMyGraphAt(1)->SetMarkerColor(3);

 ArgusHistoDisplay::SetLimits(GetMyGraphAt(icalo-1));

}

But then I get an empty pad in the tab. 
It works when I create the TGraph for only one calorimeter, using GetMyGraph().

Any help would be much appreciated.

Thanks!

Dear Colleagues

I was wondering if there was an option to analyse only ever N events in ROME. If 
this is doable via an xml switch I am guessing this would be the best and most 
convenient solution.

Else any advice on how to do this in code would be great as well -

many thanks

I added a new parameter <EventStep> to configuration XML file.
The default is 1.
If you change it to, for example 2, every second events are analyzed.

For using it, you need to
- update ROME
- compile ROME
- re-build and make your project

Once you use an existing config XML file, a new parameter will be automatically added to it.

Dear Folks 

Complete newby on online mode - hence this easy question :

I have three machines, A, B, and C.

A is where a MIDAS EventBuilder is running 
B is a gateway machine 
C is my local machine on which I want to run ROME analyser (in online mode)

A is not accessible from C. B is accesible from both A and C - 

I want to utilize the fact that I have a gateway to run ROME analyser in online 
mode reading data from A via B -

If someone could explain how to do this in detail - but in simple terms - I'd be 
grateful 

Thank you !

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

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

Hi Ryu,

I am trying to display a 2-D histogram with the <Argus> tab in the user xml file.
Here is what I have in the xml:


 <Histogram>
      <HistName>h2_Exy</HistName>
      <HistFolderName>CT</HistFolderName>
      <HistArraySize>2</HistArraySize>
      <HistType>TH2F</HistType>
      <HistXLabel>xseg</HistXLabel>

      <HistXNbins>9</HistXNbins>
      <HistXmin>0.5</HistXmin>
      <HistXmax>9.5</HistXmax>
      <HistYNbins>6</HistYNbins>
      <HistYmin>0.5</HistYmin>
      <HistYmax>6.5</HistYmax>

<Argus>

                                               <TabName>Summary</TabName>      
                                                                               
               <ObjectArrayIndex>0</ObjectArrayIndex>                          
                                                                <Index>0</Index>
                                                                               
                           </Tab>                                              
                                                                        
</Argus>                                                                       
                                                
</Histogram>

But when I compile the code it throws the following error message:

src/generated/HGUITSummary_Base.cpp:87: error: cannot convert ‘TH1F*’ to ‘TH2F*’
in assignment

I am getting this error when ever I am trying to display 2-D histograms with
<Argus> tabs.

Any help will be much appreciated.

Sudeshna

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!
Sudeshna

I've fixed the problem of not being able to define 18 tabs. I edited
/argus/include/ArgusHistoDisplay.h file:
I changed the parameter values to:

class ArgusHistoDisplay : public ArgusTab
{
protected:
   enum {
      kMaxNumberOfPads = 360,
      kMaxNumberOfPadsX = 10,
      kMaxNumberOfPadsY = 20,
      kNumberOfDisplayViewSelections0 = 54,
      kNumberOfDisplayViewSelections1 = 10,
      kNumberOfDisplayViewSelections2 = 10,
      kMaxNumberOfLines = 81
   };

Now I can define 18 tabs with 3 pads in each.

Is it possible to have the pads automatically updated with the update frequency
(set at romeConfig.xml) while using user-defined src/tabs codes? 
Suppose I write a tab code under src/tabs where I have created an "update" button. 
Now on the Argus display monitor, if I click on the "update" button, the display
will be updated. But what I've noticed is that clicking on the update button
introduces a delay. By the time the display is actually updated I've missed some
events already. 

Is there any way to sync the update button with the update frequency in the
romeConfig.xml? So that it keeps up with every event?

I would really appreciate if anyone have any suggestion for this situation.

Thanks a lot!
Sudeshna

Dear Sudeshna

The easiest way would be to call your "Update" function from EventHandler function of your tabs.

You may or may not have a function named "Update", but I believe you must have a function to update your graphics 
when your "Update" button is clicked.
You can call the same thing from EventHandler function, then it will keep the display updated.

If you want to control the frequency of the update of each tab, you can see two examples,
  $ROMESYS/examples/argus/thread/
  $ROMESYS/examples/argus/timer/
The examples update the display with using different tools (making other update thread or by using TTimer of ROOT).
