addFECInfo()

void o2::tpc::utils::addFECInfo

(

)

Definition at line 78 of file Utils.cxx.

buildChain()

TChain * o2::tpc::utils::buildChain	(	std::string_view	command,
		std::string_view	treeName,
		std::string_view	treeTitle = "",
		bool	checkSubDir = false
	)

Comman line argument can e.g. be ls *.root cat fileWithRootFiles.txt

Parameters

command	command to run
treeName	name of the tree in the chain
treeTitle	title of the tree

mergeCalPads()

void o2::tpc::utils::mergeCalPads	(	std::string_view	outputFileName,
		std::string_view	inputFileNames,
		std::string_view	calPadNames,
		bool	average = false
	)

Merge cal pad objects from different files

Requires that all objects have the same name in the differnet files. Objects are simply added.

Parameters

outputFileName	name of the output file
inputFileNames	input file names. Perforams file system 'ls' in case the string includes '.root'. Otherwise it assumes a text input file with line by line file names.
calPadNames	comma separated list of names of the CalPad objects as stored in the file.
