thanks. Did it also write the aseg.auto_noCCseg.mgz volume? That is, did mri_ca_label complete?

Hi Xiangchuan, so you found recon-all stopped in the same place (writing aseg.auto_noCCseg.label_intensities.txt)?

Source request for PPC Linux build
by Andre Gouws 19 Nov '09

19 Nov '09

Hi .. I recently spent a significant amount of time getting an automated processing stream for Freesurfer running on our OSX PPC cluster .. .. and then our IT manager upgraded all 100 nodes to Linux .. As far as I can see, there is no PPC Linux build available .. thus would it be possible for us to get hold of a previous version / the current source to compile for PPC Linux? .. or am I just not looking in the right place :) Thanks Andre' ************************************************************************ Andre Gouws York Neuroimaging Centre The Biocentre York Science Park Heslington YO10 5DG Tel: +44 (0) 1904 435328 Fax: +44 (0) 1904 435356

recon-all -all error with version 4.5
by Narly A Golestani 18 Nov '09

18 Nov '09

Dear all, I am encountering a problem with 'recon-all -all' with one subject using freesurfer version 4.5 which I did not encounter when using version 4.4. With the older version, the stream ran without error, whereas the processing produces the following error with version 4.5: ######################## ..... gca peak WM_hypointensities = 0.15609 (88) gca peak non_WM_hypointensities = 0.10304 (57) gca peak Optic_Chiasm = 0.34849 (76) mri_ca_label GCA sequential renormalization: label 28 not consistently computed. not using caudate to estimate GM means setting label Right_VentralDC based on Left_VentralDC = 1.15 x + 0 estimating mean gm scale to be 1.00 x + 0.0 estimating mean wm scale to be 1.00 x + 0.0 estimating mean csf scale to be 0.97 x + 0.0 Left_Pallidum too bright - rescaling by 0.998 (from 1.000) to 107.8 (was 108.0) Right_Pallidum too bright - rescaling by 0.998 (from 1.000) to 107.8 (was 108.0) saving intensity scales to aseg.auto_noCCseg.label_intensities.txt Linux aria 2.6.16.60-0.39.3-smp #1 SMP Mon May 11 11:46:34 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux recon-all exited with ERRORS at Wed Nov 18 04:02:23 CET 2009 ######################## I have tried simply rerunning the recon-all -all stream but the error is reproduced consistently. This seems strange since there was no such error with the very same data using version 4.4. Is there any way to correct for this problem so that the stream can run successfully? Thanks in advance and best wishes, Narly.

White matter edits - when to do manual corrections?
by Lena Palaniyappan 18 Nov '09

18 Nov '09

Dear group 1. Do we have to correct minor problems that are visible on visual inspection of white matter surface even if the surface image appears smooth with no potholes/handles? Is there any way of knowing when to start or stop manual corrections for wm/pial surfaces? 2. In the attached slice 117, you can see that the main surface is not continuous along the medial aspect of both hemispheres do we have to correct this? If yes, what is the best way of correcting this defect? 3. In the attached slice 114, the wm surface is seen outside the pial surface but tksurfer inspection does not reveal any immediately obvious defects what should I do?

Average subject registration
by Zeynep Saygin 18 Nov '09

18 Nov '09

Hi, I've made an average of my subjects using make_average_volume. I've registered each subject's orig.mgz with native-space diffusion images, and created a label-like binary image (1 for included voxels, 0 for everything else) which is in diffusion-space. I can register this back into the subject's orig.mgz space, but I'd further like to register it to the average anatomical space. Is there a register.dat file created during make_average_volume that I can use to register each subject's label files, for example, to this average subject? Thanks! Zeynep -- Zeynep M. Saygin Ph.D. Candidate Brain & Cognitive Sciences Massachusetts Institute of Technology 43 Vassar St., Room 46-4033E Cambridge, MA 02139 zsaygin(a)mit.edu 617 324 1854
