Use the registration matrix found in
$FREESURFER_HOME/average/mni152.register.dat

Hi Bruce & Martina,
Yes, the easiest is to run melodic temporal concatenation on data
pre- processed and warped into a common space by freesurfer. Melodic
does not care about the space the data lives in - everything is
reshaped into simple matrices anyways. Have a look at the melodic
command line call (in the log file) to see how to call melodic with
data pre-processed outside the FSL environment. Essentially you just
need to create a single ASCII text file containing the N different
input files (one per row) and then use
melodic -i <inputfilenames> -o <outputdir> -a concat [otheroptions]
Hope this helps
cheers

Hi Martina,
the freesurfer average subject lives in a spherical coordinate system
created using nonlinear surface-based warps, so it's very far from any
version of the mni. Maybe Steve or Christian can comment on
integration,
but certainly you would want to do the multi-subject ICA in the surface
coordinate system.
cheers,
Bruce

Hi Freesurfer,
I've run a multi-subject analysis with MELODIC(FSL), resting-state
data. Now I'd like to view
the results on the Freesurfer average subject (made with
make_average_subject)... But...
FSL uses mni152 and Freesurfer mni305. Is it true? If so... any
suggestion?
Thank you
Cheers,
Martina Campanella
