Dear Experts,
We are interested in doing Independent Component
Analysis (ICA) of
fMRI Images. We successfully modified the stica and
other ICA code
available at http://www.shef.ac.uk/psychology/stone
and used some SPM
routines to compute ICAs for fMRI images. we have used
spm_vol for reading the images , stored in a
datamatrix , performed ICA on this and have written
the resulting images in to anlyze format.
Now I would like to project the voxel intensity values
in
ICA_image files available in analyze format onto
subject's anatomical
image after doing some thresholding operation so that
I can view the
ICA's
in a more meaningful way with a color intensity bar
etc. I would also
like
to plot the time course of changes in voxel
intensities in the ICs. I
tried using spm_mip() to do the projection part but
failed.
I appreciate if you can suggest the SPM routines
useful for the
projection, thresholding, and plotting time course
operations.
Thanks very much for any help.
