Re: [Freesurfer] two questions
by Joongnam Yang 12 Jan '05

12 Jan '05

Hi, I collected new anatomical data with isometric voxels. When I ran "create surface," the pons is not being removed. I tried many different coordinates for the pons (either Volume Index or Talairach), but the pons is still not being cut out. Any suggestions? Thanks Nam.

talairach coords on TkMedit
by Joongnam Yang 12 Jan '05

12 Jan '05

Hi, TkMedit doesn't show talairach coordinates. I ran talairach2 -s subjid, and clicked (View->Information->talairach), but still talairach coords row comes out blank in TkMedit, no numbers, just 0,0,0. Would someone suggest anything to make the tal coords available o nTkMedit? Thanks. Nam.

loading curvature
by Goldman, Aaron (NIH/NIMH) 12 Jan '05

12 Jan '05

Hi, I'm writing a script to make manual editing a bit more convenient, and want to call tksurfer and tkmedit with all the parameters of csurf's "Edit Segmentation" option, and using T1 as the aux volume. Right now, I have: tksurfer $s $h inflated & tkmedit $s wm $h.orig -aux T1 However, I'm not sure how to make the curvature load automatically. Is there a flag I can add for that? Also, is there anything else that should be added/changed? Thanks, -Aaron- Aaron L.

Re: [Freesurfer] normalization failed
by Joongnam Yang 12 Jan '05

12 Jan '05

Hi, I am having trouble removing the pons with recon-all -stage1 -pons-xyz. I've tried five pons coords, unsuccessfully. When you move the mouse location in the sagittal, horizontal, and coronal images, the slice numbers change. When I get the talairach coords for the pons, should the slice numbers be the same or can they be different? Thanks. Nam.

Preproc-sess failed during smoothing
by Margaret Duff 11 Jan '05

11 Jan '05

Hi, I was trying to preprocess some functional data using the command preproc-sess -fwhm 6 -sf sessid -df sesspar. My subjects study directory is located at /space/troy/1/users/FREESURFER/SM2C2_fsfast/study. The command made it through motion correction, then during smoothing gave me this error: ERROR:: Environment variable FSLOUTPUTTYPE is not set! Please make sure that the appropriate configuration file is sourced by your shell (e.g. by putting it in .profile). e.g. bash or sh users add the line ". ${FSLDIR}/etc/fslconf/fsl.sh" e.g. tcsh or csh users add the line "source ${FSLDIR}/etc/fslconf/fsl.csh" /tmp/ipfsl_23657 /space/lyon/1/home/inverse/freesurfer_alpha/fsl/bin/ip fmc fmcsm .1 -s 2.54237288135593220338 ERROR: ip failed ERROR: ipfsl failed ERROR: spatialsmooth-sess failed I have never received this error before and am not sure if I should just set the env. variable or where the .profile is. What is the recommended course of action and is there any reason I got this error now, and never before? Thanks! Margaret

Hi all, I would like to overlay multiple functional datasets onto the same flattened structural image. How do I go about this? Thanks Ruth

mris_convert patch conversion
by Rutvik Desai 10 Jan '05

10 Jan '05

Converting pathces to ascii using mris_convert with % mris_convert -p rh.temp.patch.flat rh.temp.patch.flat.asc seems to give incorrect topology in the ascii patch (the triangles are "messed up"). I loaded the asc patch into tksurfer, and also converted it back to binary and loaded it in tksurfer. Both have the same problem. The original binary flat patch is fine. I can upload the surfaces if that would be helpful. Runninng Mac OSX 10.3.6. thanks Rutvik

pons-xyz
by Joongnam Yang 07 Jan '05

07 Jan '05

Thanks Bruce and Brian, When voxel dimensions are less than 1.75, "create surface" went smoothly. Question: The pons is still attached, I want to use -pons-xyz X Y Z TkMedit shows only RAS. (1) How can I have talairach coords shown up on TkMedit (2) RAS and Talairach coords are different, but the manual says use either one. it doesn't matter? Thanks for you answer. Nam.

recon-all exiting with errors
by Margaret Duff 07 Jan '05

07 Jan '05

Hello, I am trying to run recon-all but it seems to have some problems during nu_correct. I am using the command recon-all -subjid SM2C1tal -stage1, my subjectsdir is /space/troy/1/users/FREESURFER, and I am getting the error, Can't locate MNI/Startup.pm in @INC. then it says all the stuff @INC does contain, the says at /space/lyon/9/pubsw/Linux2/packages/mni/current/bin/nu_correct line 38. BEGIN failed--compilation aborted at /space/lyon/9/pubsw/Linux2/packages/mni/current/bin/nu_correct line 38. ERROR: nu_correct Does this have to do with the FS software or my settings or usage? Thanks, Margaret
