great, thanks Christian. I think Doug has some tools that can be used for this.

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 Christian

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
