.cat format

association file

A .cat association file (*.cat) defines which experimental design should be used when modeling each functional run. CAT files are text files containing fieldname/fieldvalues pairs using the syntax:

#fieldname

fieldvalue1

fieldvalue2

...

Association files may have a combination of the following fields:

#runs : list of runs/sessions to include in the model

enter relative run/session numbers (indexes to subset of functional runs identified in the #functionals field of a subject data.cfg file)

default: all sessions identified in the #functionals field of a subject data.cfg file

alternatively, use fieldname #abs_runs or #dicom_runs to specify absolute dicom run/session numbers, or #rel_runs or #runs to specify relative run/session numbers

#files : list of condition-information files

(enter one *.para file per run). Enter full path to file, relative paths are interpreted as relative to root.tasks (or to the #path field below if specified)

#path : (optional) path to .para files in #files field
