Hi Doug, I was trying to load the maps so I could examine each map and the overlap, as in the attached example (in this image, red is one map, blue is the other, and pink is the overlap--done in MRICRON. I think it's a nice way to view similarities and differences in activation for different groups. Although this might be achievable by merging the maps as you suggest, I was wondering if it was possible to view them in tksurfer without trying to merge them into a single map. Thanks, Scott

Hi Scott, I'm not sure what you are trying to do. How can you display two different z-values at the same voxel at the same time? Or do you want to merge the maps in some way? doug

Hi, I have 2 functional maps (Patient > Controls and Controls > Patients) and I would like to view both maps simultaneously on the surface (one with "normal" values and the other using the "inverse" values so that I get a "warm" and "cool" map simultaneously displayed on the surface). I'm using FS 5.0 and mac os 10.6.6 command from the mac terminal: > tksurfer fsaverage/ lh inflated -overlay PCC_nosmooth_level3_FE_8matched_vs_MA016.gfeat/cope1.feat/thresh_zstat1.nii.gz -overlay PCC_nosmooth_level3_FE_8matched_vs_MA016.gfeat/cope1.feat/thresh_zstat2.nii.gz
Both maps load, but I have to click on one or the other (rather than both being overlaid simultaneously), and the options (selecting inverse) seem to be applied to both layers (even though I have not selected "apply changes to all layers").
Is it possible to view these maps at the same time using tksurfer and apply normal values to one map and inverse values to the other?
It was also suggested that freeview *might* be able to do this, but this does not launch from the command line (FS, tkmedit and tksurfer all work fine).
I've copied the first few lines from the freeview crash if that helps.
Any suggestions/guidance would be appreciated.
Thanks, Scott
