Multistatic allows the inclusion of voxelwise covariates in across run/session/subject analyses in PET and fMRI imaging paradigms. It is a fairly basic adaptation of the Multistat tool that is distributed with Keith Worsleys FMRISTAT. The usage of Multistatic is identical to that of Multistat with the additional inclusion of a additional input. The additional input is a list of covariate files formatted identically to the effect files input.

Usage: df = multistatic(input_files_ef, input_files_sd, df_data, fwhm_data, X, contrast, output_file_base, which_stats, fwhm_varatio, niter, df_limit, covariate_files )
