longitudinal TRACULA -prep error
by Carissa Nicole Weis 27 Sep '18

27 Sep '18

External Email - Use Caution Hello, I'm running into an error in the longitudinal TRACULA pipeline that I'm not sure how to resolve. I saw this error in the message board but there was no resolution to the problem so I thought I'd ask again. I've successfully run the recon-all longitudinal pipeline and am trying to run the trac-all -prep step with a longitudinal configuration file. Here's the error, it happens for both time points listed in my configuration file: #@# Image corrections Thu Sep 27 12:59:31 CDT 2018 mri_convert /bigraid-03/LS/RawData/iSTAR/106_6mo/106_6mo/p516/e584/DTI_all/DTI/i10760738.MRDC.1 /bigraid-03/LS/Data/istar/freesurfer/106_6mo.fs.long.106/dmri/dwi_orig.nii.gz mri_convert /bigraid-03/LS/RawData/iSTAR/106_6mo/106_6mo/p516/e584/DTI_all/DTI/i10760738.MRDC.1 /bigraid-03/LS/Data/istar/freesurfer/106_6mo.fs.long.106/dmri/dwi_orig.nii.gz $Id: mri_convert.c,v 1.213 2014/07/29 19:22:31 fischl Exp $ reading from /bigraid-03/LS/RawData/iSTAR/106_6mo/106_6mo/p516/e584/DTI_all/DTI/i10760738.MRDC.1... crypt_gkey = *CyXds2s6sOqQ Starting DICOMRead2() dcmfile = /bigraid-03/LS/RawData/iSTAR/106_6mo/106_6mo/p516/e584/DTI_all/DTI/i10760738.MRDC.1 dcmdir = /bigraid-03/LS/RawData/iSTAR/106_6mo/106_6mo/p516/e584/DTI_all/DTI Ref Series No = 6 Found 2666 files, checking for dicoms Found 2660 dicom files in series.

Re: [Freesurfer] Reporting Cohen's D for a significant cluster
by Maksimovskiy, Arkadiy 27 Sep '18

27 Sep '18

Hi Bruce, I am including the previous correspondence below, but here is a quick summary: My goal is to get the Cohen’s D value for a max vertex of a significant cluster. I entered the max vertex number in the bottom left of the freeview window (cursor window), where it says vertex. When I hit enter, RAS coordinates change, but the vertex # goes back to what it was previously and Cohen’s D (loaded as an overlay) does not change. The cohen’s D only changes when I move the mouse and click manually. I am attaching two screenshots of the before, during entry, and after to illustrate the process. * arkadiy [cid:image001.png@01D455A5.FF5396E0][cid:image002.png@01D455A5.FF5396E0][cid:image003.png@01D455A5.FF5396E0] Previous Correspondence: Hi Arkadiy can you include the previous correspondance so we have context? And what window did you enter numbers? Was it the left hand side of the info window (under "cursor")? cheers Bruce On Wed, 26 Sep 2018, Maksimovskiy, Arkadiy wrote: Hi Bruce, I wanted to follow up on this as I was unsuccessful in doing what you suggested using Freeview (2.0)- entering numbers into the window does not change anything.

tksurfer-sess frame time course question
by 伊藤匠吾 27 Sep '18

27 Sep '18

External Email - Use Caution Hello, I am new to FreeSurfer. I conducted an experiment with event-related design. There were eight non-fixation conditions. In every trial, a simple stimulus was presented for about 1.5 sec, and the subject made a button press. I did the following analyses: preproc-sess -df sessdirfile -s YY03 -per-run -fwhm 5 -sliceorder siemens -surface fsaverage lhrh -mni305 -fsd bold mkanalysis-sess -a YY.sm5.lh -surface fsaverage lh -TR 2 -p OWN.par -event-related -fsd bold -per-run -fwhm 5 -nconditions 8 -mcextreg -fir 4 24 -polyfit 2 -force mkcontrast-sess -analysis YY.sm5.lh -contrast all_null -a 1 -a 2 -a 3 -a 4 -a 5 -a 6 -a 7 -a 8 -c 0 -rmprestim selxavg3-sess -df sessdirfile -sf sessid -analysis YY.sm5.lh then, I checked the data with tksurfer-sess (tksurfer-sess -df sessdirfile -s YY03 -analysis YY.sm5.lh -contrast all_null). When clicked Overlay/Configure, I see Frame (0-8). Frame #1 shows clear task-related activations (visual, auditory, motor areas). Because I used -fir 4 24, I think I should have 12 time points, not 9. I am currently using version 6, but I also checked the data with version 5, confirmed the same outcome. raw plots by tksurfer-sess (version 5) showed hemodynamic responses for -4 sec to 20 sec. So the data seem to have correct length. Then, I created several contrasts with -setwdelay for all_null weigting different time points like this w1_all_null : 1 0 0 0 0 0 0 0 0 0 0 0 w3_all_null : 0 0 1 0 0 0 0 0 0 0 0 0 w5_all_null : 0 0 0 0 1 0 0 0 0 0 0 0 w7_all_null : 0 0 0 0 0 0 1 0 0 0 0 0 with the following command, I see 4 frames, which probably correspond to each contrast. tksurfer-sess -df sessdirfile -s YY03 -analysis YY.sm5.lh -contrast w1_all_null -contrast w3_all_null -contrast w5_all_null -contrast w7_all_null However, when changing "frame" gives exactly the same image. (1) why did I get Frame (0-8) for my data that should have 12 frames? (2) how can I visualize contrasts created with -setwdelay? I would appreciate for any comments/suggestions.

ERROR: dimension mismatch between X and contrast
by Backhausen, Lea 27 Sep '18

27 Sep '18

External Email - Use Caution Dear FreeSurfer experts, I get this error message when running group analysis on cortical thickness using glmfit: ERROR: dimension mismatch between X and contrast Contrasts/ADHD_COM_TD_age_IQ.mtx X has 9 cols, C has 10 cols Please find attached the FSGD file, the contrast file and the terminal output below. I want to do ANCOVA with three groups (ADHD, COM and TD) controlling for the effects of age and IQ. So I assume the regressors would be ADHD COM TD age IQ and my contras matrix 1 -1 0 0 0 1 0 -1 0 0 according to information from these two tutorials: https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf3G0V and https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf2G2V. Can anybody help me out? Where am I wrong? Why does glmfit assume X has 9 cols? Any help would be much appreciated, thank you in advance!

amygdala segmentation using additional scan error
by 오진영 27 Sep '18

27 Sep '18

External Email - Use Caution Hello, freesurfer experts I'm trying to run segmentation of hippocampal subfields and nuclei of amygdala with additional scan. I already ran segmentation of hippocampal subfields and nuclei of amygdala with only T1 image, using segmentHA_T1.sh command and succeeded. After success of segmentation of amygdala with T1 image, I tried to run segmentation again with additional scan(T2 image) to get more reliable results. However, when I use command segmentHA_T2.sh, I got the following error: Error in segmentSubjectT1T2_autoEstimateAlveusML (line 2628) And the last few lines before the error are below: *Fitting mesh to image data mask took 264.2808 seconds* *Transforming points* *Transforming points* *Wrote image to file image1.mgz* *Wrote image to file image2.mgz* *INFO: dst volume info differs from the one stored in lta. gets modified now.* *volume geometry:* *extent : (232, 469, 208)* *voxel : ( 0.3333, 0.3333, 0.3333)* *x_(ras) : ( 0.0000, -1.0000, 0.0000)* *y_(ras) : ( 0.0000, 0.0000, -1.0000)* *z_(ras) : ( 1.0000, 0.0000, 0.0000)* *c_(ras) : (-21.1788, -1.8961, 3.8447)* *file : T2isotropic.mgz* *volume geometry:* *extent : (256, 256, 256)* *voxel : ( 1.0000, 1.0000, 1.0000)* *x_(ras) : ( 0.0000, -1.0000, 0.0000)* *y_(ras) : ( 0.0000, 0.0000, -1.0000)* *z_(ras) : ( 1.0000, 0.0000, 0.0000)* *c_(ras) : ( 2.3212, 8.6039, -21.1553)* *file : /Users/mnd_mac/Desktop/JY_surfer/sub_05_T2.nii* *Constructing image-to-world transform from header information (asmr1.mgz)* *Constructing image-to-world transform from header information (/Users/mnd_mac/Desktop/JY_surfer//recon_sub_05/tmp/hippoSF_T1T2_v21_T2_left/imageDump.mgz)* *Wrote image to file asmr2.mgz* *This file does not contain MRI parameters* *This file does not contain MRI parameters* *This file does not contain MRI parameters* *In an assignment A(:) = B, the number of elements in A and B must be the same.* *Error in segmentSubjectT1T2_autoEstimateAlveusML (line 2628)* *MATLAB:subsassignnumelmismatch* *Darwin MnD-macui-iMac.local 17.7.0 Darwin Kernel Version 17.7.0: Thu Jun 21 22:53:14 PDT 2018; root:xnu-4570.71.2~1/RELEASE_X86_64 x86_64* and I have no idea how to solve this problem out.

Extra sub-cortical mass
by Alec Siegel 26 Sep '18

26 Sep '18

External Email - Use Caution Hello, I'm a computer science student interested in 3D printing a model of my brain. I've successfully used freesurfer to create STL files of both my cortical and sub-cortical regions. Everything looks good except for some non-symmetrical excess mass below my cerebellum on my sub-cortical file. I'm certainly no neurologist, but it doesn't look quite right to me. I would appreciate it if someone would point out I can correct this, I am certainly willing to provide any needed files. Thanks, Alec Siegel

In case this is helpful, using a Docker (such as below), might be a helpful solution for reducing cross-platform reproducibility issues: https://mindboggle.readthedocs.io/en/latest/ -- Arkadiy L.
