[Freesurfer] cluster and FS new-version adaptation

2011-05-30 Thread Alexandru Hanganu
Dear Freesurfer experts, 1) How many simultaneous processing can be done on a cluster ? I did 20 analysis at the same time, and it worked. They all finished without error. (didn't find this question on the list) 2) In order to adapt the previous subject analysing to the new FS-5.1, must I use the

Thank you again Doug, I've tryed all the possibilities you said, but still not have a nii image, It says that it's reshaping to 6, but also when I change to another factor number it always says reshaping to 6, and the resultant nii image has still 163842 vertex so no program is able to read it

Hi Doug, The bbregister didn't work out well, it didn't register properly but I must be putting in some erroneous argument: bbregister --s SUBJ1 --mov TP.nii.gz --reg register.dat --init-fsl --t1 The final check with tkregister shows the temporal pole mask several slices off bilaterally and

access to that repository is limited to freesurfer developers. but there is a read-only version of the repository publicly accessible by these instructions: https://surfer.nmr.mgh.harvard.edu/fswiki/ReadOnlyCVS n. On Mon, 2011-05-30 at 11:57 -0400, Trina Kok wrote: > Hi all, > > I have an nmr

Hi Alex 1) depends on how many CPUs you have and how much memory is on them. We have run hundreds of recons at the same time on our cluster. 2) This depends on whether you want to keep your old edits or not. cheers Bruce On Mon, 30 May 2011, Alexandru Hanganu wrote: > Dear Freesurfer expert

Hi Kareem, can you explain a bit more about where these atlas-derived labeling comes from? Is it in MNI space? Is there any reason to think it will register well to this subject? Or is it in this individual's space? If the latter, you probably want to give -t2 to bbregister since in your case a

Yup they are acquired in the same session, so it's just the rotation and isocenter that's different. The CSI image has a different resolution ard 0.8cc. Quoting Bruce Fischl : > what is the resolution of the CSI image? Was it and the mprage > acquired in the same session? > On Sun, 29 May 2011,

Hi Bruce, Thank you for your reply. The labels are coming from me exporting the temporal pole label for a subject from fslview -- so that would mean it's in standard space? All I would need is that 4x4 affine matrix in order to calculate transformations but I'm not sure how to calculate th

then you should be able to use -regheader in tkregister2 to get close (or use -initheader in bbregister) On Mon, 30 May 2011, Trina Kok wrote: > Yup they are acquired in the same session, so it's just the rotation and > isocenter that's different. The CSI image has a different resolution ard >
