Not an easy way to do it. I guess you could create an FSFAST session for it, eg, allconcat/bold/001/all.nii.gz, then run mkanalysis-sess with -funcstem all

Alternatively, you have run the individual analyses, then isxconcat-sess, then the FFX analysis in mri_glmfit with the --yffxvar and --ffxdof options. See the --help

Hi all,

I would like to perform a fixed effects analysis on a small sample of subjects with FS-fast -- where the time series from all subjects are concatenated together and analysed in a large design matrix.

Is there an easy way to do this? I don't know if I'm looking in the wrong place but I can't seem to find it.
