different fs versions
by L. Koenders 03 Jul '12

03 Jul '12

Dear Freesurfer people, We attended the Freesurfer course in Amsterdam last week, thank you so much for the information! During the course it was mentioned that it is a very bad idea to mix Freesurfer versions during the analysis. However, we did all the preprocessing on an external server, using version 5.0.0 ('freesurfer-Linux-centos4_x86_64-stable-pub-v5.0.0') and we are currently doing all of our group-analysis on a different server, which has version 5.1.0 on it (' freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0'). Because both servers are used by a lot of people, it will become difficult to do an update on either one of these versions. Will this become a problem, or is there a way to avoid problems while still using these different versions? Thanks in advance for your help! Kind regards, Marise Machielsen, MD. Laura Koenders, MSc.

Qdec Questions
by mdkruepke＠uwalumni.com 03 Jul '12

03 Jul '12

Freesurfers- When running analysis in qdec is it possible to use each individual subjects brain volume (white matter + gray matter) as a covariate? If so, what would be the easiest way to go about getting this information. Best- Michael -- Michael D.

qdec factor.levels problem
by Anne Uhlmann 03 Jul '12

03 Jul '12

Hello FreeSurfers, I have a similar problem as described in an old thread (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg12357.html) - qdec doesn't read my factor.levels properly. I have checked the files with gedit and can't see any control characters, which might have caused the problem. Any other ideas? I have also attached the diagnosis.levels file Thank you!

regeneration of aseg.mgz following edits
by Richard Binney 02 Jul '12

02 Jul '12

Hi Freesurfers, I've been trying to understand the implications of various types of edits in an attempt to solidify some standardized procedures regarding editing strategies, particularly in severely lesioned (and thus highly vulnerable to RECON failure) brains. In doing so I've been comparing volumes surfaces and segmentions pre- and post- edits/re-running RECON. I've noticed that changes in surface reconstruction is, as expected, followed by changes in the aparc.2009s+aseg.mgz segmentation (exapnded/contracted in accordnace with surface) but I don't see similar alterations in the aseg.mgz segmentation.In fact the aseg.mgz is identical pre- and post-edits despite large changes in the WM.mgz and pial/WM surfaces. Could you explain why this might be? Thanks Richard

request for move through slices
by Michael Scheel 02 Jul '12

02 Jul '12

Dear FS experts, I am trying out freeview and am extremely fond of it. I have one feature request. In tkmedit in navigate mode it was possible moving through slices just using the mouse (middle mouse button pressed). Is it possible to implement the same in freeview - it appears that in freeview there are two zoom mouse actions scroll wheel and pressing-middle-mouse-button while moving up and down. Having this feature would ease checking and correcting data a lot. Thanks, Michael

Re: [Freesurfer] Talairach transform/coordinates not present in mgz files and/or not shown in tkmedit
by Andrew R. Dykstra 01 Jul '12

01 Jul '12

Thanks Bruce. I'll give that a try. But it seems strange to me that after processing different subjects with autorecon1 that the transform info would be missing from the header of some subjects but not others. Can you think of any reason why this might happen?
