data-class: arf3DS4 "data" class
Description
The "data" class contains all information on the fMRI data of one condition of a subject. Specifically it contains filenames of the datafiles (with full paths)
and some basic information of the data, the number of runs, and additional files used by ARF. Each instance of a model class object inherits a "data" object.
The "data" class also uses some slots of the experiment class.Objects
Objects can be created by calls of the form new("data", ...).Details
The "data" class contains information on the file-locations of the fMRI data. The fMRI data (outcomes of a GLM analysis) must be available in the /beta and /weights directories of each condition for each subject.
The data can be in the form of beta-values with associated squared standard errors or t-values with the standard errors set to 1. In the latter case the only files that have to be copied are the t-values to the /beta directory,
the weight-files are then created automatically. The average files are created after a call to createAverages.See Also
