I think the version that you have probably only reads in bfloats. We
have a newer version that will read in other formats. If this is the
case, then convert your .img to bfloat:
mri_convert yourstat.img yourstat_000.bfloat
Then in Load->Overlay, specify yourstat (not the full
yourstat_000.bfloat
Hi Bruce,
I used Tksurfer to overlay fuctional onto anatomical.
On the Load->Overlay window, I did indicate the functional *.bfloat and
register.dat, but in the "Field" at the bottom, "Overlay layer 1 (empty)" is
shown (inside "Field", all layers are empty).
I guess that something is wrong. (Shou
Hi Bruce,
We used stimuli of concentric rings whose radii expanded from trial to
trial.
We wanted to get retinotopic map using fMRI.
So, we got structural data and functional scans.
(We did the FSL Feat analysis and got stats results)
We want to see the retinotopic map corresponding to the stimul
Hi Nam,
you probably need to specify what kind of color lookup table you are using.
You'll have to give us more details about what you did for us to help
(command lines, etc...).
cheers,
Bruce

Thanks, Bruce.
When I did successfully using csurf and tkmedit (I will try tksurfer later,
though),
I saw functional data overlaid onto structural data.
Question: I was expecting some activated regions for my retinotopy data, but
all I see is a large green or red contours. Is this what freesurfe
Hi Nam,
you should be able to load the analyze format functional data directly from
within tksurfer, assuming you have a register.dat that registers it to the
structural data (use tkregister2 to generate this if you don't have it). In
tksurfer use file->load overlay and specify the .img file.

When I clicked "Volume-Stats" button on the top right corner of the window
that shows up after I clicked "View Functional Data" button of csurf,
I got the tksurfer window, but with the following error

Hi everyone,
For functional overlay,
In csurf GUI window, on the right-most side, there is a "functional" combo
box,
where you are to set two items "session" and "scandir".
Would someone tell what I am supposed to type in for those two?
Thanks

did you try specifying the cc point with mri_fill -ccwhere
the coords are in talairach?

Hi everyone,
Is there a Freesurfer command to convert ANALYZE format functional data
into *.bfloat? (I am trying to do functional overlay)
Something like,
xxx functionaldata.img *.bfloat
Or do I have to use FSL Feat to get all the thresh_zstat*.img files using
mri_convert command?
Thanks
Hi Ajay,
I'm not sure I understand. Where did you get the patch? Not from
FreeSurfer? You should be able to display activations on any surface
configuration, as long as the functional data is registered to the orig
volume.
