Thanks, I will give it a try.
Hi
creating output similar to feat output is easy, just run 'cluster'
on
any of the melodic components - you'd just have to pick a
threshold
level. This you can get from the melodic thresholded maps (in
blah.ica/stats when you click the 'Output full stats folder'
option
or when selecting --Ostats or --Oall at the command line). You can
check for the lowest non-zero value in the thresholded maps (with
avwmaths and avwstats) and then use this on the an unthresholded
melodic map. You can extract separate maps from the 4D file
melodic_IC using 'avwroi' or you can use avwsplit to split the 4D
file into a sequence of 3d files).
Using this to identify subclusters and location of local maxima is
fine, though you should be careful not to confuse the Z maps
generated by melodic with FEAT z maps generated under the null
hypothesis when regressing against a design matrix.
hope this helps

Dear FSL users:
I had posted a question yesterday to see if there is an easy way
to get the cluster information from Melodic program. Since
there was
no answer, I assume there is no easy way to do it. I wonder how
difficult would this be. Can someone comment on this?
Thanks,
