I think it may take quite a bit of programming to get most of
the routines working with your data. One thing to get you
started would be to try an undocumented feature of spm_orthviews.m:
spm_orthviews('image',spm_get(1,'*.img','Select background image'));
spm_orthviews('addimage',1,spm_get(1,'*.img','select blobs image'));

| 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.
