Overriding Gleam's jobOptions File

Often you will just want to run Gleam, but change some jobOptions parameter or redirect the output of the Root files. You can do this by supplying your own jobOptions file.

There is a feature of the jobOptions file that you can use to your advantage

the last definition of a command wins

So you can override any Gleam option by providing your own. The recommended method of operating is to #include Gleam's basicOptions.txt file in yours, and then override to your heart's content.

Here is a sample (notes [] are not part of the file!). This sample will run simulation + recon + write output Root files. Aside from paths, the file is equally applicable to Windows and Linux.

Notes:

[1] - include Gleam's basicOptions
[2] - uncomment this if you want the gui
[3] - set the debug level a little less chatty if you want. It's interesting to see all the messages the first few times.
[4] - reset where the Root files go. The paths here are just examples from one of my configurations.
[5] - if you need a special source, you can specify your own source file
[6] - pick the source you want
[7] - add other algorithms if you so please.
Gaudi provides two ways to override. In [5] you see '=', and in [7], you see '+='. '=' sets the value, '+=' adds to the list. So [7] adds an algorithm and DLL to the lists, while [5] resets the source list. One could have used '+=' there too, but I believe you have to watch out for duplicate sources in the various files.

To run this on Linux:

glastpack.pl run Gleam Gleam.exe myPath/jobOptions.txt

where myPath is the location of the file.

In vcmt, you would run Gleam, but in the run options box, supply

myPath/jobOptions.txt
