Detailed Description

Manage an experimental dataset corresponding to a given experiment or campaign.

In KaliVeda, all experimental data is divided into datasets described by a KVDataSet object. These objects are not usually set up individually by hand, but rather they are created when a KVDataSetManager object is initialised, using the informations in files contained in specific directories, one for each dataset (see the subdirectories of the datasets/ directory in the top-level source directory of KaliVeda, or https://gitlab.in2p3.fr/kaliveda-dev/datasets):

KVDataSetManager dsm;

dsm.Init();

KVDataSetManager

Manage all datasets contained in a given data repository.

Definition: KVDataSetManager.h:39

KVDataSetManager::Init

virtual Bool_t Init(KVDataRepository *=0)

Definition: KVDataSetManager.cpp:65

After initialisation, each dataset can be accessed using a global pointer to the current KVDataSetManager, using the dataset name:

auto ds = gDataSetManager->GetDataSet("[name of dataset]");

KVDataSetManager::GetDataSet

KVDataSet * GetDataSet(Int_t) const

Return pointer to DataSet using index in list of all datasets, index>=0.

Definition: KVDataSetManager.cpp:378

In many situations, such as e.g. when running analysis of some data, the associated dataset is set as the 'currently active' dataset, which means that it can be accessed through another global pointer,

-// set currently active dataset
gDataSetManager->GetDataSet("[name of dataset]")->cd();
-// print name of currently active dataset
std::cout << gDataSet->GetName() << std::endl;

Each dataset has an associated database (KVExpDB object) which contains all available information concerning the experimental data and its calibration. When the 'currently active' dataset has been defined, a global pointer to the associated database can also be used:

-// list all reaction systems associated with current dataset

gExpDB->GetSystems()->ls();

KVExpDB::GetSystems

virtual KVSeqCollection * GetSystems() const

Definition: KVExpDB.h:114

TCollection::ls

void ls(Option_t *option="") const override

The gDataSet global pointer can also be used to open (and read) data files associated with the dataset, but only if there is an associated KVDataRepository containing such files. In order to open data files, instead of initialising a KVDataSetManager as shown above, you should begin by initialising a KVDataRepositoryManager:

KVDataRepositoryManager drm;

drm.Init();

KVDataRepositoryManager

Manages access to one or more data repositories.

Definition: KVDataRepositoryManager.h:47

KVDataRepositoryManager::Init

void Init()

Definition: KVDataRepositoryManager.cpp:67

Note that each data repository has an associated dataset manager, therefore after initialisation of the repository manager, the global gDataSetManager will give access to the datasets associated with the 'currently active' data repository, accessible through global pointer gDataRepository: there is no need to create a separate KVDataSetManager object:

KVDataRepositoryManager drm;
drm.Init();
-// set "[name of dataset]" as 'currently active' dataset
gDataSetManager->GetDataSet("[name of dataset]")->cd();
-// list all reaction systems associated with current dataset "[name of dataset]":
gExpDB->GetSystems()->ls();

Consulting the catalogue of available data files of each type (raw, recon, etc.), and opening files for analysis can then be done using the global gDataSet pointer:

-// get list of run/index numbers of all available files containing reconstructed events
auto rl = gDataSet->GetRunList("recon");
-// get full path to a given runfile: here, raw data file index 3 of run 12
std::cout << gDataSet->GetFullPathToRunfile("raw", {12,3}) << std::endl;
-// open a runfile for reading
auto rdr = gDataSet->OpenRunfile<KVRawDataReader>("raw", {12,3});
rdr->GetRunInfos().Print();

See list of methods below for more details.

Dataset configuration variables

The following variables are used to tune/tweak the definition of a dataset. In each case, a default value exists which is applied to all datasets, whereas prefixing the variable name with the name of a specific dataset applies to just that dataset.

The value defined for the currently active dataset for any of these variables can be consulted using

std::cout << gDataSet->GetDataSetEnv("KVDataSet.DataTypes") << std::endl;

KVDataSet::GetDataSetEnv

ValType GetDataSetEnv(const Char_t *type, const ValType &defval) const

Definition: KVDataSet.h:252

Variable	Role	Example
`KVDataSet.DataTypes`	Different types of data which can be associated with datasets	"raw recon"
`KVDataSet.DataType.Subdir.[type]`	Names used for subdirectories containing data of different types	"raw"
`DataSet.RunFileName.[type]`	Default formats for runfile names (run number is used to replace integer format)	"run_%R.dat"
`DataSet.RunFileClass.[type]`	Default base classes for reading runfiles of different types	"KVRawDataReader", "TFile"

Definition at line 490 of file KVDataSet.cpp.

◆ cd()

void KVDataSet::cd ( ) const

Makes this dataset the "currently active" or default dataset.

At the same time, the database and data repository associated with this dataset also become the "currently active" ones:

global pointer	represents	base class
`gDataSet`	active dataset	KVDataSet
`gExpDB`	associated experimental database	KVExpDB
`gDataRepository`	repository containing runfiles	KVDataRepository

◆ CheckAvailable()

void KVDataSet::CheckAvailable ( )

virtual

Check if this data set is physically present and available for analysis.

In other words we check if the value of GetDataPathSubdir() is a subdirectory of the current data repository. If so, we proceed to check for the existence of sudirectories corresponding to any of the datatypes associated with the dataset.

Definition at line 443 of file KVDataSet.cpp.

◆ CheckMultiRunfiles()

void KVDataSet::CheckMultiRunfiles ( const Char_t * data_type )

Check all runs for a given datatype and make sure that only one version exists for each runfile. If not, we print a report on the runfiles which occur multiple times, with the associated date and file name.

		KVDataRepository *	other_repos
	)

Use this method to check whether the file of type "data_type" for run number "run" in the data repository "other_repos" is more recent than the file contained in the data repository corresponding to this dataset. Returns kFALSE if file in other repository is more recent.

Definition at line 1439 of file KVDataSet.cpp.

◆ CheckUpToDate()

void KVDataSet::CheckUpToDate	(	const Char_t *	data_type,
		const Char_t *	other_repos
	)

Check whether all files of type "data_type" for run number "run" in the data repository are up to date (i.e. at least as recent) as compared to the files in data repository "other_repos".

Definition at line 1498 of file KVDataSet.cpp.

◆ CheckUserCanAccess()

Bool_t KVDataSet::CheckUserCanAccess ( )

virtual

if fUserGroups has been set with SetUserGroups(), we check that the current user's name (gSystem->GetUserInfo()->fUser) appears in at least one of the groups in the list. Returns kFALSE if user's name is not found in any of the groups. if fUserGroups="" (default), we return kTRUE for all users.

void KVDataSet::CleanMultiRunfiles	(	const Char_t *	data_type,
		Bool_t	confirm = `kTRUE`
	)

Check all runs for a given datatype and make sure that only one version exists for each run. If not, we print a report on the runfiles which occur multiple times, with the associated date and file name, and then we destroy all but the most recent version of the file in the repository, and update the runlist accordingly. By default, we ask for confirmation before deleting each file. Call with confirm=kFALSE to delete WITHOUT CONFIRMATION (DANGER!! WARNING!!!)

Definition at line 1368 of file KVDataSet.cpp.

◆ GetAnalysisTask() [1/2]

KVDataAnalysisTask * KVDataSet::GetAnalysisTask ( const Char_t * keywords ) const

This method returns a pointer to the available analysis task whose description (title) contains all of the whitespace-separated keywords (which may be regular expressions) given in the string "keywords". The comparison is case-insensitive.

WARNING: this method can only be used to access analysis tasks that are available for this dataset, i.e. for which the corresponding prerequisite data type is available in the repository. For unavailable data/tasks, use GetAnalysisTaskAny(const Char_t*).

EXAMPLES Let us suppose that the current dataset has the following list of tasks:

root [2] gDataSet->Print("tasks")
Event reconstruction from raw data (raw->recon)
Analysis of raw data
Identification of reconstructed events (recon->ident)
Analysis of reconstructed events (recon)
Analysis of partially identified & calibrated reconstructed events (ident)
Analysis of fully calibrated physical data (root)

Then the following will occur:

root [14] gDataSet->GetAnalysisTask("raw->recon")->Print()
KVDataAnalysisTask : Event reconstruction from raw data (raw->recon)
 
root [10] gDataSet->GetAnalysisTask("analysis root")->Print()
KVDataAnalysisTask : Analysis of fully calibrated physical data (root)
