Overinclusive white matter surface
by Kathryn Devaney 24 Apr '09

24 Apr '09

Hello freesurfers, I am running a reconstruction of a macaque in stabe4, and I am having a problem with the smooth white matter surface not following the wm boundary in the wm.mgz volume (please see attached for examples in the wm and T1 volumes). The non-wm area included in the surface was never part of the wm volume, but I edited the other defects in wm.mgz and re-ran fill, tessellate, smooth1, inflate1, qsphere, fix, finalsurfs, smooth2, amd inflate2. Unsurprisingly, this problem persisted. Is there anything that I can do to fix this? Thanks! Katie

Thanks for the quick responses. Is there an easy way to enable these drivers? (We unfortunately don't have an IT linux expert here).

tkmedit error
by Dana W. Moore 23 Apr '09

23 Apr '09

I am processing a new brain on the same linux station I've been using FreeSurfer successfuly on for months now, but when I recently rebooted the machine, I got a message saying it was running in basic display/graphics mode. I don't know why the machine went into this mode. Now, when I try to view an image on tkmedit, I get this error: GLUT: Fatal Error in tkmedit: OpenGL GLX extension not supported by display I am going to try to figure out how to get the machine back into its normal display mode. But in the meantime, I am running a reconstruction and am wondering--can I trust the stats I get in the current mode? Is this just a display problem, or do I need to re-run the entire reconstruction once the problem is fixed? Thanks, Dana Dana W.

Different volumes in ?h.aparc.stats and wmparc.stats
by Wayne Su 23 Apr '09

23 Apr '09

I looked into the ctx volumes reported in ?h.aparc.stats (such as frontalpole) and the same one in wmparc.stats (labelled as ctx-?h-frontalpole). The volumes are slightly different. I am wondering why this happened and which one is better. Thanks. Wayne

mouse/rodent neuro-imaging data analysis
by Siddharth Srivastava 23 Apr '09

23 Apr '09

Hi everyone, I would like to get the opinion of the users on this, regarding the feasibility of using freesurfer for analyzing mouse imaging data, provided that we have at our disposal, a supporting atlas. I know that Caret provided a fine scale parcellation for this species. Are there users on this list who have developed a working pipeline that uses freesurfer as one of the components to process such a data? It would be a great help if i can hear from some of you on the most optimal (open source/freeware) way of going about it. I am currently inclined towards using freesurfer+caret+slicer as enabling components for the analysis. Amy thoughts would be highly appreciated. best regards, sid.

ROIs of BV not coinciding with FS
by Barnali Basu 22 Apr '09

22 Apr '09

Hello Thanks for your previous responses. Those have been helpful. I have been trying to use some ROIs generated in BrainVoyager(BV). I have converted the ROI text file of BV to Freesurfer label text file format, using a small perl script (attached as testperl.txt). I am also attaching the original BV ROI file and the changed FS label file for your reference. My method seemed to work( no error), however all the ROIs , regardless of where they should be ( like frontal, MT etc) are landing up on the occipital area, including the occipital ROI itself. The BV ROI data sent to me was generated in Tal space, also, I have done manual Talairaching to the same data in FS using tkregister2. So I assume both versions of the subject (BV and FS) are in same space. Am I right? It would be great if you could suggest me where I must be going wrong. FYI, the BV processing has been done on a windows machine and sent to me. I work only on FS on Ubuntu. I am also attaching pictures of frontal and an occipital ROI on the inflated brain. Looking forward to some help. -- Barnali Basu Cell : 425 638 2936 Home: 206 257 0174

qdec versions for .Qdecrc
by raka maitra 22 Apr '09

22 Apr '09

Hello I am using Freesurfer v 4.1.0 I would like to have the advantage of the updated qdec of v 4.2 or 4.3 for my data. Specifically, I would like to use the 'MEASURE# = some_measure' modification for .Qdecrc Is it advisable to replace the qdec, qdec_glmfit and qdec.bin (from freesurfer/bin) in the 4.1 version with that of 4.2. or 4.3 ? Will that be sufficient ? Thanks in advance Raka
