Q: Does anybody know how to create a FWHM file with glim_image? I have noticed that there are some options that look interesting (e.g.-fwhm_gauss), but I seem to be facing syntax problems. It would be great if anybody could provide me with an example command line.

A: Given that no-one else seems to have had a crack at this my guess is that you are after something with which you can evaluate your mean fit?

In this case I’m guessing you want this:

  glim_image \ 
      -t_stat  stats.mnc t_stat voxel column 2 \ 
      -fwhm \ 
      -fwhm_avg fwhm.mnc \ 
      file.glim

Note that I have not tested the above but from dim-dark memory this seems to ring a bell.
