how to get freeview run on ubunto
by yawu Liu 04 Oct '12

04 Oct '12

Hi Freesurfers, I have installed Freesurfer 5.1 in my Ubunto. I run analysis with testing and our won data without problem. But when I run: d4201z-CELSIUS-M470-2:/usr/local/src/freesurfer/subjects/long-tutorial> freeview -v OAS2_0001/mri/norm.mgz, then Error message appears:freeview.bin: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory. Any help is appreciated! Best Regards, Yawu

fixing the talairach.xfm
by Eric Cunningham 04 Oct '12

04 Oct '12

Hi, I have a few very basic clarification questions regarding the recon-all processing pipeline. I am currently following the instructions here: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach Near the end of the page, it instructs me to rerun the whole process using my new talairach, using the command: recon-all -all -subjid [subjid] Questions: (1) Since the talairach file is created during recon-all, wouldn't rerunning the whole process overwrite my freshly edited file with whatever it came up with the first time? (2) Assuming the answer to question 1 is 'no', can i rerun the process in steps (-autorecon1, then -autorecons 2 and 3) without overwriting my freshly edited file? (3) Are there any files that are unusual in their likelihood of being overwritten? (e.g. running recon-all -all will overwrite aseg.stats but not talairach.xfm) Thank you for your help, -Eric

More than two time-points in longitudinal base = Memory allocation error?
by Liz Bowman 03 Oct '12

03 Oct '12

Hello, I have several patients scans taken over multiple time points (up to nine time points in some patients). I thought I might be able to use these to create a base template for longitudinal processing, however the process fails and exits with errors if I try to create a base with more than two time points from a patient. This is a sample of the error log of the most recent attempt, with three timepoints: Resolution: 1 S( 128 128 128 ) T( 128 128 128 ) Iteration(f): 1 -- diff. to prev. transform: 0.876663 Iteration(f): 2 -- diff. to prev. transform: 0.0148738 Iteration(f): 3 -- diff. to prev. transform: 0.00156813 < 0.01 :-) Resolution: 0 S( 256 256 256 ) T( 256 256 256 ) Iteration(f): 1 -- diff. to prev. transform: 0.263086 Iteration(f): 2mri_robust_template(1035) malloc: *** mmap(size=262144) failed (error code=12)*** error: can't allocate region*** set a breakpoint in malloc_error_break to debugMRIalloc(256, 256, 256): could not allocate 262144 bytes for 68th slice Cannot allocate memoryDarwin 550D-UOM88670.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:32:41 PDT 2011; root:xnu-1504.15.3~1/RELEASE_X86_64 x86_64 recon-all -s KSx3 exited with ERRORS at Mon Jul 23 10:15:13 EST 2012 For more details, see the log file /Applications/freesurfer/subjects/KSx3/scripts/recon-all.logTo report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting I would be grateful for any advice.

is skull strip needed
by Gregory Kirk 03 Oct '12

03 Oct '12

if there is extra skull left after skull stripping but the pial surface is fine ( i.e. the left skull did not get included in the pial surface ) is it nessesary to adjust watershed parameters or manually remove it and reprocess the data set ? I am thinking it is not needed if it is not causing an error in the surface. thanks greg

A question about downsmapling mulitple surfaces (white, pial, sphere) for registration
by Longchuan Li 03 Oct '12

03 Oct '12

Hi, FreeSurfer experts Currently, I am planning to run tractography using wm surfaces as seed masks and pial surfaces as stop masks implemented in FSL. In order to make fibers go through one hemisphere to another, I need to remove the medial wall from both seed surfaces and the pial surfaces. However, as the original surfaces' resolution is too high, I will need to downsample the surfaces first, in order to manage the computational time to a reasonable time limit. My strategy is like this: (1) downasample the sphere, pial and white from original 700K to 10K using "mris_decimate" with a factor of 0.1 (2) register the subject's downsampled sphere to the template surface sphere (3) transfer the label file with medial wall excluded from the template space to the subject's sphere space based on the warping file. (4) convert the label file to seed mask (based on white surface) and stop mask (based on pial surface). using a FSL tool My questions are: (1) Can surface-based registration be properly done when I used the downsampled version of the sphere to register to the template's sphere? (2) As my pial, sphere and white surfaces are downsampled separately by repeatedly using the "mris_decimate", will they still have that point-to-point correspondence as the original ones? I would appreciate if anyone could help on this and point out any potential problems and/or better strategies Longchuan

Re: [Freesurfer] Lesioned brain (surface) registration to fs average
by octavian lie 03 Oct '12

03 Oct '12

Actually, the white matter is affected too within the resection bed. Just to make sure, using mri_label2label with surface option to pass a label from subject 1 to subject 2 is equivalent to registering that label to fsaverage via sphere.reg for that subject, then transferring the label from fs average to subject 2 via sphere.reg for subject 2. I assume I can use it to transfer the label to fsaverage as well; is it better or same/equivalent to use mri_surf2surf vs mri_label2label to transfer a label from one subject to another Thank you very much, Octavian.

Configuring freesurfer developer's environment on Ubuntu
by Kim, Daniel 03 Oct '12

03 Oct '12

Hello freesurfer users! I've got a brand new PC with Ubuntu 12.04 64-bit running and following the freesurfer developer's guide to set up a developer environment, I'm getting numerous "undeclared function / undefined type" errors during make. Seeing that the undeclared functions or variable types are actually defined in .h files that are being declared correctly, I'm suspecting there's configuration problem and was wondering has anyone had success in building freesurfer on Ubuntu 12.04 64-bit or building freesurfer on any previous Ubuntu release? The steps I took to get as far as getting undeclared function/undefined type errors are: - Pre-built 3rd party libraries were downloaded and put into /usr/pubsw/packages/ During configuration, I've made modification to bypass errors: - changed configure script so that script will not end when libvtkfreetype, libBLT is "not found" by the script, although, I have the .so files in the correct library - disabled -Werror flag - copied /usr/bin/libtool into ~/dev/ in order to avoid libtool version mismatch error - In Makefile for ~/utils/ commented out any rules for unwarpGradientNonLinearity since this file is no where to be seen Thank you for any advice and pointers!

Skullstrip error issue
by Rashmi Singh 03 Oct '12

03 Oct '12

Hello experts, I am getting skull strip issues with FreeSurfer recon-all runs in every data. I ran recon-all on my T1-data and noticed that the skullstrip is not so good. Almost in every subjects there were dura included, so I tried the suggestion of using the flags -skullstrip and -Clean–bm and –gcut in my recon-all command line for one subject. Forexmaple: I ran reconall using the following command lin: recon-all –skullstrip first -clean–bm –gcut –s AA***.T* -all -use–mritotal The run was complete and I looked at the brainmask.mgz file of the output. But I didn't see any correction. I am attaching the jpg image of the sagittal view of brainmask.nii ( I converted the mgz file to nii to view tham in afni) SubjFS: is the image from recon-all run SubjFS: is the image from recon-all that was run with Skullstrip/clean-bm/gcut options included. Did I do anything wrong? Your guidance and suggestion needed. Thanks, Rashmi.

mri_glmfit and --mask
by Brain Apprentice 02 Oct '12

02 Oct '12

Hello everyone, I am trying to incorporate a binary FMRI mask into mri_glmfit. The problem is that it does not matter what I put in for the mask file I get the same results. This is the command I am using: mri_glmfit \ --y /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2/y.mgh \ --fsgd /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2/qdec.fsgd dods \ --glmdir /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2-msk6 \ --surf fsaverage lh \ --mask /shared/subjects/4-aut-v510/a-aut-v510/3-long/<Files listed below>\ --label /shared/subjects/4-aut-v510/a-aut-v510/3-long/fsaverage/label/lh.aparc.label \ --C /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2/contrasts/lh-Avg-Intercept-thickness.mat \ --C /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2/contrasts/lh-Avg-thickness-TOMAL_COMPOSITE_MEMORY_INDEX-Cor.mat \ --C /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2/contrasts/lh-Diff-Control-ASD-Intercept-thickness.mat \ --C /shared/subjects/4-aut-v510/a-aut-v510/3-long/qdec/test2/contrasts/lh-Diff-Control-ASD-Cor-thickness-TOMAL_COMPOSITE_MEMORY_INDEX.mat Here are the files that are getting inserted: DMN-b.mgz - Is a binary version of FMRI activation. DMN2-b.mgz - Is a binary file with nothing but zeros. DMN3-b.mgz - Is a binary file with nothing but ones.. I should also point out that the glmdir directory is changing with each new run of mri_glmfit. There is one other thing I should mention, and that is the above command other than the --mask part I got from qdec including the contrast1.mat part. I am sure it is me and I am doing something wrong. If someone can suggest an alternative I would be most grateful. Thanks
