Dear Sudeshna

Unfortunately, with the current ROME, it is not possible to insert own code when you use <Argus> blocks for 
which the source code is supposed to be generated automatically (and not editable).

If you want to do more than the automatically generated code, you can use the normal type tabs although you 
need to program it by yourself (as you program tasks).

An example is $ROMESYS/examples/midas.
In midas.xml, you can find <Tabs> section where several normal tabs are defined.
Corresponding source files will be generated in src/tabs when you run romebuilder after modifying the 
definition 
XML.

As for source files of tasks, you can edit the source files of tabs as you want.
ROMEbuilder will not overwrite the files.
You can draw any ROOT GUI objects in the tabs including text.

You can get the pointer of histograms associated to a task.
For example, in the midas example, src/tabs/MIDTADCTab.cpp, a pointer of a histogram 'ADC' of 
'FillHistogram' 
task is obtained by
  gAnalyzer->GetFillHistogramTask()->GetADCAt(i)

Please let me know if you have any problems to write code for your tabs.

Best regards,

Ryu
