/usr/lib/libstdc++.so.5 is missing I have /usr/lib/libstdc++.so.6
by Keith Sudheimer 03 Aug '07

03 Aug '07

I am running a Fedor Core 4 machine and have installed the CentOS 4 version of freesurfer. I can run tkmedit and tksurfer. However, I am running into trouble running trhough recon-all -s 004FSC -autorecon1 When I get to Nu Intensity Correction (mri_nu_correct.mni) on iteration1, during volume stats calculations, I get a missing file error in /usr/lib/libstdc++.so.5 in /usr/lib/ I do have a /usr/lib/libstdc++.so.6 but no libstdc++.so.5 any advice or tips would be greatly appreciated. Thank you.

Growing spots
by Troy Mcan 02 Aug '07

02 Aug '07

Hi,I have a group of talairach coordinates on a brain that I would like to grow to a specified amount (e.g. 8 mm radius). Is there a function in freesurfer that allows me to do this? Also, some of the points are far away from the main group, but I would like to have them all connected. Is there a blur filter or an equivalent that I can use to accomplish this?Thank you! _________________________________________________________________ Recharge--play some free games.

writing surface file
by Marie Schaer 02 Aug '07

02 Aug '07

Hello everybody, I would like to write a surface in freesurfer format from a matlab triangular mesh (e.g. list of 67120 vertices associated with 134236 faces). To read the freesurfer surfaces, I usually use the very useful bioelectromagnetism toolbox by Darren Weber, but I am not able to find out why the freesurfer_write_surface function (attached to this mail) do not work with my mesh. It indeed seems to write a surface of adequate size (2.3MB), but when I try to visualize it, tkmedit respond: "(null): vertex 0 x coordinate 282617032931096509022208.000000 ! " Does someone has any hints on that or an available matlab script to write a freesurfer surface? Many thanks for your help, Marie Schaer

RE: [Freesurfer] Ubuntu, Xeon 64bit multi-core, and freesurfer

Thanks for your response Nick! Would you be able to also give us an update on when the next release is going to be available and whether it will include white matter parcellation? I need to reprocess a fairly large number of scans and I would prefer if it includes the latest bells and whistles. Regards, Nic -----Original Message----- From: Nick Schmansky [mailto:nicks@nmr.mgh.harvard.edu] Sent: Tuesday, 31 July 2007 12:07 PM To: Nicolas Cherbuin Cc: Freesurfer Mailing List Subject: Re: [Freesurfer] Ubuntu, Xeon 64bit multi-core, and freesurfer Nic, Concerning Ubuntu and Freesurfer, we have not used that OS directly ourselves, but I believe people on the list have used Ubuntu and Freesurfer. I think there were some library issues, but nothing that was a show-stopper or overly difficult to fix. We have many Xeon dual core machines in use here, so Freesurfer should run fine on that. Your plan run a recon-all on each processor is fine.

measurement of cortical thickness
by T. Song 01 Aug '07

01 Aug '07

Hi All: I am trying to measure the cortical thickness of specific ROI. I got a ROI, and are able to save it to a label file. Should I use mris_thickness to measure the thickness? If so, how do I get the thickness file, using mri_label2vol? Thanks in advance! Tao

Keyboard Mapping (up arrow)
by Troy Mcan 01 Aug '07

01 Aug '07

Hi,Does anyone know how to access the "up arrow" (history) command in the tksurfer shell. E.g. backspace maps to ctl-h. Thanks! _________________________________________________________________ PC Magazine’s 2007 editors’ choice for best web mail—award-winning Windows Live Hotmail. http://imagine-windowslive.com/hotmail/?locale=en-us&ocid=TXT_TAGHM_migrati…

negative value for CWP low
by Robert Levy 31 Jul '07

31 Jul '07

Hello, I tried a between group comparison using mri_glmfit, correcting for multiple comparisons using the z-based monte carlo method. This differed from previous similar analyses I had run in that I did not constrain the analysis with a ROI (not in the glmfit, but I did in surfcluster when outputting corrected results). It seems like something is buggy about this output, but it may actually be correct but I just don't know how to interpret it correctly. The negative CWPLow probability values for certain clusters are what seems puzzling. I don't know what a negative p value could possibly mean [ it is beyond impossible for the cluster to be unreal? : ) ], though I'm sure it's not a real p value. These are not significant clusters regardless, but these are impossible statistics and so I was concerned that something was breaking down in the process that would invalidate the other results. The second part of what I tried possibly shows that there is something going wrong in the code, just because it is drastically different when I would only expect a minor difference (and probably in the opposite direction actually). I ran surfcluster with no ROI, and the same cluster became much more significant than it was reported as being before. This seems strange, so I don't know whether the other results in the same unconstrained analysis are correct. I have included some of the surfcluster output (and attached both of the example files), and the environment and commands.

Using Par/Rec Data
by Andrew Ellison 31 Jul '07

31 Jul '07

Hi im asking if anyone has experience analyzing data from Par/Rec, whether it be convert them to analyze or run analysis on them as is. I am using par/rec and have gotten stuck, and am simply wondering if others have been able to sucesfully take Par./ Rec. data and use it in freesurfer, and if so how exactly it was done because i am having problems that may stem back to the Par/Rec format. Thanks! -Andy

Fake thickness map 2
by Inês Souta 31 Jul '07

31 Jul '07

Hello, I was trying to create a cortical thickness map with constant values in order to perform some tests. At first I tried using mris_convert. I converted my thickness file into ascii: mris_convert lh.thickness lh.thickess.asc then I used matlab to change all the values in the last column to 2,0. I tried to convert the ascii file back to surface file by doing mris_convert lh.thicness.asc lh.thickness but I got "Segmentation fault". How can I convert may ascii file into a surface one? After failling to acomplish this, I tried using the save_mgh and load_mgh file, nevertheless I'm not quite sure which input values are needed. Where can I put my fake values in the save_mgh file? And what is "vol"? Thanks, Ines

If you don't need to do that, you can pretty much ignore it. > It just means you can't launch the app with & to put it in the > background. Since you must be running under X11 anyway the following is a dirty work around (in csh): xterm -e tkmedit -f /full/path/to/your/data/example.mgz & this will run the tcl shell in another window, that gets "dispatched" from your main window without blocking control there. But it feels somewhat hackish... BTW the tcl shell should end once you quit tkmedit/tksurfer hope that helps Sebastian > > On Thu, 2007-07-26 at 11:33 -0600, Troy Mcan wrote: >> Hi, >> >> When I type freesurfer in my terminal, a new shell opens up (with >> full >> keyboard functionality), in which I type tksurfer (with its >> parameters) or tkmedit (with its parameters).
