HI Assaf, Are these 6-7 T1 volumes all collected in the same 1 hour imaging session?
yes
If so, it isn't clear what you are trying to do -- brain structure is not going to be changing over the course of 1 hour.
ya, I know, I know. - thanks!
Still, I would like to check it out.
cheers, -MH

P.s. when they are all done you will want to run the longitudinal stream to create a base, then again on each timepoint

I see. Call recon-all once for each image with a different subject I'd

Those are different time points in the same session (10 minute interval between each acquisition)
What are you trying to achieve?
What I would like to achieve ? I would like to get a segmentation for each one of those brain MRI images...
Why? I would like to compare ""the dynamics"" in a different brain region during this one hour MRI session...(Not sure if/how much wise it is... butthis is what I want... for now....) Thanks!!

This is exactly the command I've used.
However, as I mentioned my subject has about six or seven T1-MRI images and I have added all of them via the ""recon-all -i image1 -i image2 etc'" command. I can even see those images in the "mri/orig" directory. see:
| |-- orig | | |-- 001-iscale.txt | | |-- 001.lta | | |-- 001.mgz | | |-- 002-iscale.txt | | |-- 002.lta | | |-- 002.mgz | | |-- 003-iscale.txt | | |-- 003.lta | | |-- 003.mgz | | |-- 004-iscale.txt | | |-- 004.lta | | `-- 004.mgz ... ...However, I'm not sure how can I used tkmedit to inspect the segmentation of those different MRI images ?
[Hope my question is more clear now]

tkmedit <subject name> norm.mgz lh.white -segmentation aparc+aseg.mgz or tkmedit <subject name> norm.mgz lh.white -segmentation aparc2009s+aseg.mgz the tools will be part of FS 5.2 when it comes out in the next month or so. If you really need it before then Nick can get you a beta. cheers Bruce On Sat, 1 Dec 2012, Assaf B. Spanier wrote: Many thanks for the quick response - I would take a look on your suggestion! How about my first question ? About viewing the segmentation results of my first trial ( without the Flair images) [Please forgive my English :) ] On Sat, Dec 1, 2012 at 9:53 PM, Bruce Fischl <fischl@nmr.mgh.harvard.edu> wrote: Hi Spanier definitely don't invoke recon-all with the FLAIR image. We have some tools in 5.2 for this, but you would call it as a postprocessing step with a different command line in any case. Instead, you can use bbregister to register the flair to the surfaces and resample it. cheers Bruce On Sat, 1 Dec 2012, Assaf B.

Follow this, I used the "recon-all -all" command. (For about two days...) Here come Question 1: After all this process, I didn't completely follow the results I got... As I have noticed that I have only one segmentation file (aparc.a2009s+aseg.mgz) ? How can I see the segmentation result with tkmedit in the different brain images ? = B = As I would like the neuroanatomical labels to be inspected for accuracy by a physician. My physician asks to see the segmentation result on top of the Flair images (saying it easier for him to do so on Flair images) So I've used the "recon-all -i image1 -i image2 etc'" command again but this time I've also included the Flair image. Here come Question 2: However, this time, unfortunately, the "recon-all -i image1 -i image2 etc'" , failed, saying that: ~~~~~ images have different voxel sizes. Currently not supported, maybe first make conform? Debug info: size(1) = 0.5078, 0.5078, 5.5 size(0) = 0.51, 0.51, 5.5 ~~~~~ Is there something I can do to fix this ?
