Quick question. If I scanned a single subject across several sessions and want to do a fixed effects analysis on that subject's brain (without registering to MNI or Talairach space), how do I go about doing this? I am trying to us isxconcat-sess and then mri_glmfit, but I am not seeing an option to simply do the analysis in native space instead of registering to a standard brain. Is there a way to do this besides taking the end result of the analysis and doing the reverse registration back to the subject's brain?
