Dear Community, I need to know how can I read the numeric cortical thickness values from freesurfer processed files. (as there are too many in the surf folder) Thank you. Best Regards Naveed

FSFAST mkcontrast-sess with spmhrf 2 question
by Joseph Dien 25 Mar '16

25 Mar '16

Hi, I have a question about how mkcontrast-sess works. I ran an analysis using the mkanalysis-sess option spmhrf 2 so there are three regressors for each predictor, the primary, the latency, and the dispersion. When specifying the contrast weights for mkcontrast-sess, the documentation indicates that they are specified in terms of the conditions as numbered in the paradigm file, not the individual regressors. Furthermore there only appears to be one contrast value output for each contrast, not three. How are the three regressors being handled? I can think of several scenarios: 1) the contrast weights are not actually in terms of conditions (the documentation is incorrect), they are actually in terms of the regressors (so contrasting conditions 1 and 2 could be specified as -a 1 -a 2 -a 3 -c 4 -c 5 -c 6). 2) the latency and dispersion regressors are being ignored (a common practice). The contrast weights should therefore be specified as -a 1 -c 2. 3) The Calhoun et al (2004) approach is being used to combine the three regressors into a "derivative boost" amplitude measure. The contrast weights should therefore be specified as -a 1 -c 2. Thanks for any help you can give me!

DEPRECATED warning in Freesurfers
by Peter Wendorff 13 Oct '15

13 Oct '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. I'm working with freesurfer as a software developer in a cloud project. My task is to enable control of freesurfer via network (e.g. REST interfaces). That works fine so far, but I stumbled over the following pearl deprecated warning: "Use of ?PATTERN? without explicit operator is deprecated at /usr/local/freesurfer//mni/bin/sharpen_volume line 153." Which has been printed to the log files repeatingly. I'm not a pearl expert, but I think, it's due to a more up to date pearl version used here, that deprecated the usage of ? delimiters for patterns without explicit operator. Using / as a delimiter works fine. I changed that locally to (new line 153): ($output_volume =~ /^([\S]+).mnc/) && ($base_name = $1) || die "sharpen_volume failed: output volume does not appear to be" ." a minc volume.\n"; (the original code here was): ($output_volume =~ ?^([\S]+).mnc?) && ($base_name = $1) || die "sharpen_volume failed: output volume does not appear to be" ." a minc volume.\n"; I'm not sure this is the best solution. It's even not strictly necessary to change this - it's only a warning that's thrown; but I think, it's useful. How can I submit this as a patch? Is it enough to report here? What to do? regards Peter Wendorff P.S.: For referene the header parameters of my sharpen_volume for revision comparison: #---------------------------------------------------------------------------- #$RCSfile: sharpen_volume.in,v $ #$Revision: 1.1 $ #$Author: bert $ #$Date: 2003/04/16 14:29:34 $ #$State: Exp $ #--------------------------------------------------------------------------- # ------------------------------ MNI Header - ---------------------------------- #@NAME : sharpen_volume #@INPUT : #@OUTPUT : #@RETURNS : #@DESCRIPTION: modifies intensities so as to produce a sharper histogram #@METHOD : #@GLOBALS : #@CALLS : #@CREATED : February 28, 1996 #@MODIFIED : #----------------------------------------------------------------------------- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlGTa5kACgkQi8ffXNvWmYSCUQCghMg1EffqfeJK4PSfo20uF8/J H0MAnjJc0WbHPf5gLDUw70K8fnQPjS+L =g+6e -----END PGP SIGNATURE-----

Re: [Freesurfer] possible to use freesurfer segmentations to get mean values for anatomic structures from other sequences
by Douglas Greve 25 Sep '14

25 Sep '14

Hi Sal, yes you can. Use bbregister to register the lowb image to the anatomical. This creates a registration matrix. Use mri_vol2vol and the registration to map the ADC map to the anatomical, then use mri_segstats to extract the values doug ps. Please post questions to the FS list instead of us directly so that others can benefit and it gets archived. thanks!

V1 label
by krista kelly 24 Apr '14

24 Apr '14

Hello, I am looking at cortical thickness and surface area using Freesurfer. I have transferred label V1 from freesurfer onto the brains of my participants and when I view them on the inflated brains in tksurfer , I notice that there are holes in the label. Is this an issue when calculating mean cortical thickness and total surface area estimations? Should I fill these in somehow? I've attached a picture to show as an example. Please let me know if the picture cannot be viewed. Thanks! Krista

Re: [Freesurfer] Fwd: white matter and pial surface don't track sulcus
by Darren Gitelman 06 Dec '13

06 Dec '13

Yes. That's it. I tried editing the wm.mgz earlier and deleting all voxels labels as ventricle (250) but that didn't solve the problem. Do I edit the aseg.mgz file and just label it as none in this region? Would I use the command tkmedit <subjid> brainmask.mgz -aux brain.finalsurfs.mgz -surfs -segmentation aseg.mgz $FREESURFER_HOME/FreeSurferColorLUT.txt When done do I run recon-all -autorecon2-noaseg -autorecon3?

possible pial surface editing

Hi! All, We ran into a few cases which the wm matter surface is pretty decent but pial surface did not go far enough to include all gray matter. Is there a way to fix this?

preferred method for generating appropriate bvecs for tracula
by Salil Soman 01 Nov '13

01 Nov '13

Hi, I have dicoms that I turn to nifti using dcm2nii (with the default settings plus anonymization option turned on [-a y]). The bvec files it generates by default are 3 rows by n columns (where n is b0 number + directions). I am under the impression tracula requires this to be converted to a n row by 3 column file. 1) is this correct, 2) is there a preferred way to perform this transformation on linux systems? Thanks you, -Sal
