registering .gfeat
by Stacy Chu 12 Jul '07

12 Jul '07

Hi Doug, I am trying to use reg-feat2anat to project FEAT results onto the FS surface. This works ok (except for some registration problems discussed earlier) for 1st level .feat directories. However, my study consists of two consecutive runs per subject (to allow the subject to take a break), so preprocessing for each run is first done seperately on the 1st level. Then at the second level the two runs are averaged together using FEATS fixed effects analysis. Now I have one .gfeat folder which combines both runs. It seems that not all files that reg-feat2anat requires are in the .gfeat folder. So I copied the .1stlevel.feat/reg/example_func2standard.mat to 2ndlevel.gfeat/reg/example_func2standard.mat. Now I get an error that the .../freesurfer/tmp/exfbet file can't be found. I have attached the log file. Your help would be much appreciated. Thanks, Stacy ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Hi All: After imposing labels to a T1.mgz files in tkmedit, is it possible to write out dicom files with the label? Thanks in advance! Tao

doesn't find .dcm-files for "mri_convert -it dicom ..."
by Birte Schrader 12 Jul '07

12 Jul '07

Hello, I just downloaded and installed the freesurfer and got up the step where I tested it by trying "recon-all -s bert -autorecon1". This works fine :-) Now I (thoroughly) followed the instructions "Getting started with your own data" in of https://surfer.nmr.mgh.harvard.edu/fswiki/ TestingFreeSurfer. But unfortunately the mri_convert command does not work on (my?) dicom-files: "mri_convert -it dicom -ot mgz avant/ avant.mgz" is what I type in. I am really in mri/orig/ and in mri/orig/avant are 120 .dcm-files so I don't see what's wrong. I get the error message: "reading from avant/... no DICOM files found. Exit" Do you know if there are different types if dicom-files and not all of them are supported? Or do you see anything else that might be wrong? Thanks in advance. Birte PS: The FreeSurfer software was highly recommended to me by a friend of a friend of mine, so I am really looking forward to trying it on my data... PPS: tkmedit and tksurfer do not work yet for me. But that is some problem with displaying the windows. I get "GLUT: Fatal Error in tksurfer.bin: could not open display:". But this shouldn't alter the no-display-functions of freesurfer, no? Visualization I can do otherwise if I cannot fix it...

Re: [Freesurfer] FreeSurfer relevance for studying structures other than the bra
by Greg Soltis 11 Jul '07

11 Jul '07

Howdie Doug, We are interested in studying not the ventricles, per say, but the actual cells and components of the cells that comprise these ventricles. For example, cells from a heart, spleen, sperm, or cochlea. Since we are not using an MRI machine to obtain the images, is FreeSurfer of no use to us? (You said it handles only TI-weighted MRI data). Additionally, you mentioned in a previous correspondence that as our files traverse along the data stream in FreeSurfer, they will ultimately be converted into 8-bit format. However, since we need the files in 16-bit format, would this be a deal-breaker as well? Thanks.

FreeSurfer relevance for studying structures other than the brain
by Greg Soltis 10 Jul '07

10 Jul '07

Greetings, I am attempting to use FreeSurfer/Slicer to study data from a mass sprectrometer. To be of use, the segmentation capability of FreeSurfer/Slicer has to be based on quantitative data, not morphology. It appears as if FreeSurfer uses a generic mapping of the brain's structure as a starting point for the model it generates. However, for one seeking to study a structure other than the brain, this can be a concern. Can FreeSurfer/Slicer accommodate data whose source is not an MRI and or of the brain? This concern also stems from the file entitled "SlicerTraining06_vtkFreeSurferReaders.ppt" provided on a Slicer site that has about a dozen tutorials for Slicer 2.6 (this is one of them). On Slide #25, entitled 'Determining label numbers in an ASEG file', there is a list of the first 30 sections created and various parameters. The names of these sections seem to be predetermined (i.e., Left Cerebral-Exterior, Left Cerebral-White-Matter, Left Cerebral-Cortex, etc.). This seems to imply that FreeSurfer/Slicer know what to look for from the onset and thus the segementation is not based solely on quantitative data. Please let me know if these conclusions are warranted. If I am mistaken, please advise as to why. Thanks for your time and advice, Greg _________________________________________________________________ Need a brain boost? Recharge with a stimulating game.

smoothing and monte carlo sim
by Robert Levy 10 Jul '07

10 Jul '07

Hi Doug, As you suggested, I ran mc simulation data with a threshold taken from fwhm.dat so that the smoothing on the simulation matches the smoothing on the real data. What I was wondering is, if I use the same simulation data for several contrasts (they have the same fsgd, so this seems like a valid thing to do), it becomes less clear how to choose the smoothing. Or maybe it is not possible to use the same mc simulation data, because the smoothing turns out to be different. Should I instead use an average of the smoothing values, or maybe use the lowest one? Conceptually it seems like this might make the results less accurate, but in practice is there a certain level of slack in smoothing without sacrificing accuracy? If not, it makes a big difference, because the full simulation will take 6 days instead of 2. The z simulation, which at at least with the level of smoothing we have applied, showed results being much less significant, which is why I'm trying the full mc simulation. Thanks, Rob Just to give you an idea of the variance in the smoothing reported in fwhm.dat for the three contrasts: lh.ASvfix_8s_BwGroupError5.fsfast.glmdir/fwhm.dat 17.128043 rh.ASvfix_8s_BwGroupError5.fsfast.glmdir/fwhm.dat 16.675573 lh.ASevASc_8s_BwGroupError5.fsfast.glmdir/fwhm.dat 15.202638 rh.ASevASc_8s_BwGroupError5.fsfast.glmdir/fwhm.dat 15.771982 lh.ASevfix_8s_BwGroupError5.fsfast.glmdir/fwhm.dat 14.438915 rh.ASevfix_8s_BwGroupError5.fsfast.glmdir/fwhm.dat 15.766636 -- Robert P.

mri_motion_correct.fsl problems
by Catherine Hartley 10 Jul '07

10 Jul '07

Hi, I'm still having problems with the rawavg.mgz volume being generated with incorrect orientations. I gave Jenni two 00?.mgz volumes and she was able to generate a correctly-oriented rawavg. Our two log files look very different, but I'm not able to figure out the problem by looking at them. To start with, the i_ras, j_ras, and k_ras value for the 00?.mgz volumes are different in each of our log files. Mine also has several warnings in which it says that it cannot read a matfile, and that the hist.orient value is not valid. I've attached the log files. Any suggestions would be very very welcome. Thanks in advance, Cate

MR to MGZ
by Jerry Yeou-Wei Chen 10 Jul '07

Hello, We have been having difficulties importing GE .MR files into FreeSurfer. We have tried a number of methods: 1) directly importing .MR 2) converting to .IMG via BrainVoyager, then importing .IMG with .HDR 3) converting to .IMG via BrainVoyager and creating .MAT using SPM99, then importing .IMG with .HDR and .MAT 4) renaming .MR to .DCM, then importing .DCM Here is a summary of our problems: 1) autorecon1 exits with error 2) orig.mgz is in wrong orientation; T1.mgz is in correct orientation but a "cosine info" error arises when loading in tkmedit; brainmask.mgz is in wrong orientation; reconstructed surface is in wrong orientation (i.e. not actually a hemisphere; appears oblique) 3) orig, T1, and brainmask are all in wrong orientation 4) autorecon1 exits with error (in all cases except reconstructed surface, "wrong orientation" means: C = axial with anterior to the left and right to the top H = sagittal upside-down S = coronal with superior to the left ) Here is a summary of what seems to be the source of our errors, from corresponding recon-all.log files (I have attached .doc and .txt files with longer excerpts) 1) mri_convert /home/omid/freesurfer/subjects/IBS_raw/csd/mri/rawavg.mgz /home/omid/freesurfer/subjects/IBS_raw/csd/mri/orig.mgz --conform MRIresample(): source matrix has zero determinant; matrix is: -0.000 0.000 -0.000 0.000; 0.000 0.000 0.000 -15877550310885762478336514187067392.000; 0.000 -0.000 -0.000 -2013832203448376356765696.000; 0.000 0.000 0.000 1.000; 2) mri_convert /home/omid/freesurfer/subjects/IBS_fromBV/_orig_/c1/sd0823iso.img /home/omid/freesurfer/subjects/IBS_fromBV/c1/mri/orig/001.mgz ----------------------------------------------------------------- INFO: could not find /home/omid/freesurfer/subjects/IBS_fromBV/_orig_/c1/sd0823iso.mat file for direction cosine info.
