Custom ROI surface visualization
by Shannon Buckley 23 Jul '14

23 Jul '14

Hi experts, I'm trying to create a pretty picture via Freesurfer / freeview. Specifically, I have 6 regions that I want to combine into 2 rois (1 color for each 3-region-roi ) that would display over a gray-background. So in Freeivew, my goal is to see a gray pial surface with roiA displayed in red and roiB displayed as blue with all other labels present, but gray. I've already read through the FAQ and attempted what I've seen work for others, but I seem to be hitting some kind of trouble and I'm not sure which steps / flags to adjust. Here is what I've tried so far: 1) mri_annotation2label -surf pial -hemi rh -outdir ./roi a. This got me all my rh.label files . 2) Then I used: mri_mergelabels -i rh.insula.label -i rh.fusiform.label -i rh.isthmuscingulate.label -o rh.ins_fus_icing.label (and repeat this for the next roi, using different labels) a. This got me a 2 new .label files that overlay great in Freeview if I load them individually on the rh.pial surface. The problem is that I can only seem to load ONE label at a time for the overlay, which does not meet my goal. So, to load multiple labels I tried combining them via. 3) mris_label2annot --s $code --hemi rh --ctab /home/vhasfcbuckls/Freesurfery/$code/label/roi/roi_added_bgGray.aparc.annot. ctab \ --a newrois.graybg.aparc --l /home/vhasfcbuckls/Freesurfery/$code/label/roi/rh.ins_fus_icing.label \ --l /home/vhasfcbuckls/Freesurfery/PPMI_012_S_3181m00_i357579/label/roi/rh.ling_ tpole_parah.label I've attached 2 screenshots: one where I've successfully loaded just ONE of the ROIs on the rh.pial (roiA_label_loaded.png); the other shows what I see after loading the product from step3 (annot_loaded_roiAB_graybg.png), which shows all 6 regions, but they aren't grouped into 2 rois by color, and the background is black instead of gray. The annotation seems to think I only have the 2 regions indicated in the std out (below), which is unexpected. I feel like there is some flag I'm missing here. I've attached the modified ctab file used as an input to mris_label2annot, wherein I've appended my custom labels to the standard aparc.annot.ctab and assigned new RGB colors. All other regions were changed to 127 127 127 0 to make them gray. Question: Can you please tell me which steps / flags/ inputs that need adjustments in order to reach my goal? Or is there a better tool / method that I should use for this visualization instead? Please let me know if you need more information. Thanks very much for your time, ~Shannon +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Here is the std out for step3: mris_label2annot --s $code --h rh --ctab /home/vhasfcbuckls/Freesurfery/PPMI_012_S_3181m00_i357579/label/roi/roi_adde d_GrayBG.aparc.annot.ctab --a newrois.graybg.aparc --l /home/vhasfcbuckls/Freesurfery/PPMI_012_S_3181m00_i357579/label/roi/rh.ins_f us_icing.label --l /home/vhasfcbuckls/Freesurfery/PPMI_012_S_3181m00_i357579/label/roi/rh.ling_ tpole_parah.label Using Freesurfer version 5.1.

dwi_motion Tracula
by Cat Chong 23 Jul '14

23 Jul '14

Hello Anastasia, I ran Tracula on Freesurfer 5.3 but without the 2013 Tracula updates. Now, I would like to use the command "dwi_motion" on my data. I have installed the updates, but will I have to completely reprocess my data inducing steps trac-all -prep, trace-all -bedp, and trac-all path in order to use dwi_motion? cheers, Cat

Watershed
by SOURAV RANJAN KOLE 22 Jul '14

22 Jul '14

Hello Freesurfer community, 1. I am using watershed to perform more aggressive skull stripping but it seems to be not working for me. Command I am using: recon-all -subjid 1203 -skullstrip -wsthresh 10 -clean-bm -no-wsgcaatlas -no-isrunning Please see attachments for before and after watershed images. After watershed, skull stripping seems almost worse and it is not respecting the manual edits that I have done either. You can see the manual edits in the Before_Watershed.png file if you zoom in. 2. Which version of FreeSurfer do I need to have to use gcut as it is giving me the following error- recon-all -skullstrip -clean-bm -gcut -subjid 10 ERROR: Flag -gcut unrecognized. This is the FreeSurfer version that I am using: freesurfer-Darwin-leopard-i686-stable-pub-v4.4.0 Thank you very much for your help. Regards, Sourav

question regarding control point edits
by Adam Mezher 22 Jul '14

22 Jul '14

Hi FreeSurfer group, I was wondering if there is a way to include control points in my command line when I run recon-all. We are working with a large dataset and many of the subjects have underestimations in the anterior temporal lobes so it would be beneficial to expand the WM surface slightly on numerous cases rather than doing control point edits on each case individually. Thank you, Adam Mezher

Question with QDEC annotations and mri_convert and mri_annotation2label
by Tara Ann Miskovich 22 Jul '14

22 Jul '14

Hello, I am trying to convert my significant cluster from qdec into a .gii file, and I have a couple of questions. My mri_convert is not working, but it is my first time using it so I may be missing something, but it just keeps opening up the usage and gives no errors. mris_convert --annot mc-z.abs.th13.sig.ocn.annot mc-z.abs.th13.sig.ocn.gii Also, I was curious, how would one separate a annotation file created in qdec into separate label files with mri_annotation2label since there is no target subject which is required in he script. Thanks! Tara

ERROR: Could not open [..]/bvals for reading
by Elia S. 22 Jul '14

22 Jul '14

Dear Freesurfer Community, Running Tracula preprocessing produces this error: ERROR: Could not open /home/elia/scripts/Tracula/LCL/dcmTimePoints_tar/T13D/timePoint1/dmri/bvals for reading I think the error described is the same as here: https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg34169.html And as suggested here (https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2014-February/035935…) I swapped the dmri_motion from the centos4 updates with the dmri_motion from the centos6 updates, and it works. Now here's the situation, I need to run tracula on machines where is not possibile to install the centos6 updates, since the message i get is this: error while loading shared libraries: libnetcdf.so.6: cannot open shared object file: No such file or directory Do you have any advice for me?

freeserver versions
by Gianluca Rambaldelli 22 Jul '14

22 Jul '14

Hi, two years ago I processed a lot of data using freesurfer v5.1. Now I'm using v5.3 on a different group of subjects, I'm wondering if I can use together all the subjects from the different versions. Or there is a way to re-run it using the last version? I suppose that I can copy the 'control.dat' file that I saved into the new version but how can I add wm edits if I didn't saved it in a single file (for example edit.dat). Instead of creating an edit file, I saved every variations onto brainmask.mgz changing the original mask created by the recon -all procedure. I need to compare those old subjects because after a machine upgrade it has been installed the new version and I started a new project with v5.3. Thank you Gianluca Rambaldelli

Extract curvind，folding, gauscurv, meancurv, thickness std in the whole vertices
by Qiongmin 22 Jul '14

22 Jul '14

Dear Experts, I used ‘mri_surf2surf’ to get the area, thickness, volume of all the vertices in the brain. I am wondering what functions can I use to get other information, such as ‘curvind, foldind, gauscurv, meancurv, thicknessstd’ ? I know FreeSurfer provides these statistic data according to two kinds of parcellations of the brain, but I need these information in a vertex-wise way. Thanks very much! Best, Qiongmin

Thickness measurements on longitudinal data set
by Bastian Cheng 22 Jul '14

22 Jul '14

Dear Freesurfer-Experts, I am currently trying to measure Cortical Thickness of a Volume-defined ROI in a patient measured at 4 timepoints. Basically, I am interested in a ROI resulting from fMRI activation measured on Timepoint 1. I would then like to get thickness values in the same ROI for all Timepoints 1-4. I have read the instructions here: https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness this works. now, my idea is: ROI from TP1 >> register to base image of longit. recon. ("base") ROI from base >> TP1.long (from long recon) ROI from base >> TP2.long (from long recon) ROI from base >> TP3 long (from long recon) ROI from base >> TP4.long (from long recon) OR should I simpy map my ROI to fsaverage and project it back all individual timepoints? ROI from TP1 >> register to fsaverage ROI from fsaverage >> TP1 (not from long recon) ROI from fsaverage >> TP2 (not from long recon) etc. I understand that registration using the long. recon is more robust... Best regards, Bastian
