FreeSurfers, I am using mri_volcluster on the output of a fixed-effects analysis, but am getting an error regarding my register.dat file. The register.dat file I'm directing mri_volcluster to is in the group's tal-ffx directory and lists subject "talairach". mri_volcluster is thus looking for subject "talairach" in my SUBJECTS_DIR. The problem is there's no such subject in SUBJECTS_DIR. Here's the message-ERROR: cannot find subject talairach in /exp/REfMRI/mg_2_21/structurals/. How do I fix this? Is a Talairach subject supposed to be put in SUBJECTS_DIR when I run func2tal-sess, or is this a part of a library I should have somewhere? Or do I create this file? Any help would be appreciated. Thanks! Dan Dillon

NIFTI Files
by Marek Kosinski 26 Feb '07

26 Feb '07

Hi, I am a freesurfer starter. I am trying to overlay statistical maps ,which I've created with FSL, on the brain surface. I've some questions regarding to that: 1) can the newest version of freesurfer deal with NIFTI files? (Because everytime when I try to use NIFTI files I get an error message.) 2) how can use mat files which I create with FSL-Flirt to overlay functional maps to the brain surface? 3) I do not want to use talaraich registration. Is there a possibility to omit talaraich registration. Thanks a lot Marek ___________________________________________________________ Der frühe Vogel fängt den Wurm.

how to get with BOLD change
by Lucia Maria Vaina 26 Feb '07

26 Feb '07

Hi: We're trying to do a correlation analysis between BOLD % Signal Change and behavioral performance. The fMRI data is being analyzed using freesurfer (specifically, the program roisummary-sess, see https://surfer.nmr.mgh.harvard.edu/fswiki/roisummary_2dsess? action=highlight&value=roisummary-sess). This program outputs a couple values (detailed on that page), notably, the number of voxels in the area, the number that were active above statistical threshold, and the "mean functional baseline offset". Unfortunately, since I am a novice in Freesurgfe, it's unclear to me how to get a % signal change from this data. Presumably, the offset value says something about the difference in activity between the on and off periods, but I don't know the exact meaning of this value, and how to get a % signal change from it. We get a single output file per run (~280s) and have 12 runs total (8 on day 1, 6 on day 2). We have various behavior metrics corresponding to each of these. I'm attaching one of the output files here. Thanks a lot! Lucia n002-task-3-008 98 32 1093.3451 8.9397 76.000000 3.300000 0.000000 1 1 7.8309

Why the .auto.-files?
by Oddbjørn Sæther 23 Feb '07

23 Feb '07

Hi, what is the meaning of the .auto.-files generated? In autorecon1 the brainmask.auto.mgz is generated, and thereafter copied to brainmask.mgz. The same for aseg.auto.mgz in autorecon2. What is the difference between "with/without" auto? Thanks in advance, oddbjørn

Hi Freesurfer experts, I have encountered the following error running the reconall -autorecon2 script, blurring input image with Gaussian with sigma=2.000... 0000: dt=0.000, rms=0.474, neg=0, invalid=1511 0445: dt=0.080000, rms=0.471 (0.499%), neg=0, invalid=1Segmentation fault ERROR: mri_ca_register with non-zero status The complete ouput from the log file is attached below. I ran the autorecon1 earlier without any errors. The talirach transformation and skull stripping went fine on examination. There were also no memory errors logged in var/spool/mail directory. I am currently using Red Hat Enterprise Linux Client release 4.91 (Tikanga), with 2GB RAM on 64-bit Intel dual core. I would greatly appreciate any help on this.

mri_convert fails for enhanced MR IOD DICOMs
by Martin Kavec 23 Feb '07

23 Feb '07

Hi, our MR scanner produces DICOMs with enhance MR IOD, i.e. multiframe image file. When I try to use this format with FreeSurfer mri_convert fails. I assume it is not designed for this type of images, isn't it? Anybody knows a workaround? Thanks in advance for help (and great software), Martin

importing EEG coordinates in free surfer
by abel cruz vadell 23 Feb '07

23 Feb '07

Hi everyone I need to import EEG coordinates (obtained with Polhemus system in ASCII format) in the FreeSurfer workspace. My final aim is characterize small areas of the cortical surface (exactly the regions underlaying my sensors position) with typical parameters of FreeSurfer (cortical thikness,...) . I have read some papers reporting partial solutions to my needs. All of them used matlab with some exported files of FreeSurfer and registered them with the coordinates of the EEG or MEG analysis. I will like to have an opposite solution: import the file with the coordinates of the EEG into the FreeSufer workspace, maybe using the Load/overlay /registration menu of FreeSurfer or another that you can suggest me. I guess my coordinates file needs some transformations before import it to the FreeSurfer workspace thanks in advance abel ______________________________________________ LLama Gratis a cualquier PC del Mundo.

Topology fixing
by Juergen Haenggi 23 Feb '07

23 Feb '07

Dear Freesurfer users the topology fixer is running since about 18 hours on the same defect Correcting defect 100 (vertices=23181, convex hull=7929) In contrast to the other defects, the number of vertices involved in this defect is very large. Any idea?

Maximum number of subjects in make_average_subject?
by martijn van den heuvel 22 Feb '07

22 Feb '07

Dear Freesurfer-list, I'm trying to construct an average group surface map using 'make_average_subject'. My group consists of a rather large number of subjects, around 400 subjects. Unfortunately, running 'make_average_subject' gives an error when processing subject 253, saying it has an 'mgh reading error' on the 'T1.mgz'. I checked that the involved files are all oke. In addition, I have run 'make_average_subject' several times with different group lists, but every time it stops at subject 253. I'm using an Intel MacPro with 16 GB of system memory, and there is plenty of free memory when it runs. Is there a maximum set on the number of subjects you can use in 'make_average_subject'? Can I reset this value? Yours sincerely, Martijn van den Heuvel

lh.thickness error
by Joongnam Yang 22 Feb '07

Hi all, I was doing mri_vol2surf to overlay functional average(FSL) onto anatomical average (Freesurfer) and got the following error message, ERROR: .................. Reading thickness /home/nam/V4RET/average/surf/lh.thickness MRISreadCurvature: could not open /home/nam/V4RET/average/surf/lh.thickness No such file or directory .................. Is "make_average_subject" supposed to produce "lh.thickness"? Please let me know what is wrong? Thanks, Nam. My command was: mri_vol2surf --src /home/nam/V4RET/FUNC/AVG/LMhori.gfeat/cope1.feat/thresh_zstat1.img --src_type analyze --srcreg register.dat --hemi lh --projfrac 0.5 --out /home/nam/V4RET/FUNC/AVG/LMhori.gfeat/cope1.feat/thresh_zstat1-lh.w --out_type paint
