auto segmentation editing
by David Soscia 23 Aug '05

23 Aug '05

Guys, If you run the auto segmentation editor in the new program, does it do the defect editing (optical nerve, fornix, lateral ventricle, basal ganglia) for you, eliminating the time it takes to do this? If this is true, it is a life (and time) saver for me. Dave David A.

Stage 1 Problem
by Daniel Goldman 22 Aug '05

22 Aug '05

Hello, When I try running the stage one portion of the recon-all script on one of my subjects, the skull-stripping removes everything above the ears and everything but the skull below the ears. When I run mri_watershed, it works just fine. Any idea what I might have done wrong in running the stage one portion to have caused this? - Daniel #----------------# Daniel Goldman CENAGN @ MGH-NMR #----------------#

Fw: Re: [Freesurfer] coregistration
by antao＠itsa.ucsf.edu 22 Aug '05

22 Aug '05

I have a image xAD1378-T1.img with spm format. after I converted it to COR with mri_convert xAD1378-T1.img AD1378/mri/orig and run FLIRT as Xiao suggests, I found that the anterior and posterior parts of tranformed image was inversed. Xiao thinks it is due to mri_convert, Does anyone know how to fix it? thx, Antao ---------- Forwarded message ---------- From: Xiao Han <xhan(a)nmr.mgh.harvard.edu> Date: Mon, 22 Aug 2005 16:03:46 -0400 (EDT) Subject: Re: [Freesurfer] coregistration It has nothing to do with fsl_register. It's because of the conversion from .img to COR format. That's why I suggested you to convert all your data to COR or mgz first before processing. The reason is because Analyze store data in an anterior-to-posterior fashion, but when mri_convert read the data, it assumed posterior-to-anterior (due to a missing .mat file). I dont know how to fix that.

Tiger and MNI Linear Register
by Yuan-Fen Kuo 22 Aug '05

22 Aug '05

Hi. I have installed the freesurfer-Darwin-tiger-full.dmg and I would like to use the MNI Linear Register option. I have been prompted that "MNI has not been align not yet implemented." Because of this message, I have changed my SetUpFreeSurfer.csh script so that the following directories are pointed to the corresponding path instead of the default that came with the package. MINC_BIN_DIR /Users/Shared/freesurfer/lib/mni/bin MINC_LIB_DIR /Users/Shared/freesurfer/lib/mni/lib PERL5LIB /System/Library/Perl/5.8.6 However, I still get the same message. Is there something I am missing? Thanks in advance. Eric

Re: [Freesurfer] process volume again
by David Soscia 22 Aug '05

22 Aug '05

Thanks, after a little tweaking, I managed to get part of the process going. A few things I thought I would mention though... 1. At first when I tried to do the -nuintensitycor command it was saying it found no data in /mri (no orig.mgz file there). When I did mksubjdirs, it made folders for all of the steps (orig, T1, wm, brain, etc) And then when I did a conversion to mgz from dicom of my orig files, they went into my orig folder, ie. mri/orig/orig.mgz. Maybe I did the conversion wrong so it sent it there instead of in the mri directory, however I thought the purpose of the mksibjdirs was to make seperate folders to put the seperate steps into. After I saw this error message in the -nuintensitycor process, I moved the orig.mgz file from the orig directory into the mri directory and it worked fine. 2. When I run the next step, -normalization, I am getting an error half way through...

I recently installed freesurfer on my Linux machine that runs RH9. When running tkmedit , I get the following error: tkmedit: error while loading shared libraries: libtk8.3.so: cannot open shared object file: No such file or directory I tried a solution posted to a simliar problem by downloading the lib files, but I got this message: rpm -i {tcl,tk}-8.3.2-1.i386.rpm package tcl-8.3.5-88 (which is newer than tcl-8.3.2-1) is already installed How do I get rid of this problem?
