Hi Bruce, I Have sent the raw data to you and I find if it is the problem of tksurfer Installing? Can it result in the problem? How can I Fix it?

import from caret
by Colin Reveley 14 Dec '13

14 Dec '13

Hi - If one has a surface that is aligned to a volume in CARET, is it possible (or rather, is there a general procedure) to export the volume and the surface into freesurfer? The volume in CARET won't be conformed. It's header will define the origin such that CARET interprets a specific voxel/coordinate as the anterior commisure. The surface will be aligned to the volume in the sense that it's co-ordinates are with respect to that anterior commisure definition. What I need to do is run mri_convert -c to conform the volume, and then convert the surface to freesurfer format in such a way that it's now aligned to the conformed volume in freesurfer. Then I'd do some stuff (refine the surface) in freesurfer, and export the surface back to CARET. That's the general issue. Details include: the surface will need to be transformed so that it appears to freesurfer to be 1mm data, and the volume will have it's header changed so that it claims 1mm voxels (the data is higher resolution than 1mm). The problem can be considered as finding the inverse of Van Essen's Freesurfer to F99 pipeline. Or, "Surefit to Freesurfer" is a better way to look at it. The surfaces are *white and *pial though. It's some scaling, translating, conforming and format conversions. Other stuff is not a worry. connectome workbench, FS, CARET, FSL, MATLAB whatever are all relevant/involved tools hope can help Colin Reveley

error loading surface on one machine, but not another
by Ryan Mruczek 13 Dec '13

13 Dec '13

Hi All I created surfaces for a particular subject on one machine, and subsequently copied the entire subjects surface directory to another machine (both running OSX, although different versions). On the second machine, I cannot load the lh surfaces files. For example % tksurfer LS lh white produces the following output and error (last line): tksurfer LS lh white subject is LS hemi is lh surface is white surfer: current subjects dir: /Users/rmruczek/MR_DATA/surfaces surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /Users/rmruczek/MR_DATA/surfaces/LS/surf checking for nofix files in 'white' Reading image info (/Users/rmruczek/MR_DATA/surfaces/LS) Reading /Users/rmruczek/MR_DATA/surfaces/LS/mri/orig.mgz surfer: Reading header info from /Users/rmruczek/MR_DATA/surfaces/LS/mri/orig.mgz mrisFindNeighbors: /Users/rmruczek/MR_DATA/surfaces/LS/surf/lh.white: face[0].v[0] = 0, but face 0 not in vertex 0 face list This is a problem for all of the left hemisphere surfaces on the new machine. The same command executes fine on the original machine. Also, the right hemisphere surfaces load fine on the second machine. I've double checked that the files were copied completely and were not truncated. Has anyone experienced something similar or have an idea of what is going on? Thanks! Cheers, Ryan

problem creating annotation using mri_sample_parc?
by Markus Gschwind 13 Dec '13

13 Dec '13

Dear all, I am trying to create a annotation file from a ROI_file with multiple ROIs with values form 1:10 using mris_sample_parc I had verified that myROIfile and subject001/surf/rh.white and also mri/T1.mgz loadable together in freeview (=same space). when running the command mris_sample_parc -v -sdir subject001 rh ~/Documents/myROIfile.mgz rh.myROIfile.annot it first starts well, but then complains about could not open translation file /Applications/freesurfer/cma_parcellation_colors.txt However when trying to load the created annotation file it gives me the same never endign error: CTABfindAnnotation: ct was NULL No such file or directory CTABfindAnnotation: ct was NULL No such file or directory CTABfindAnnotation: ct was NULL No such file or directory CTABfindAnnotation: ct was NULL No such file or directory ... etc. I guess that the annotation is not on the surface, but what am I doing wrong? Thank you in advance, Markus

funcroi commands
by Emily Boeke 13 Dec '13

13 Dec '13

Hi Freesurfers, I would like to make sure I am using the funcroi commands correctly for anatomical and functional ROI analyses (using the aseg to anatomically constrain), and I have some questions about the commands. If I want to extract the average percent signal change in the whole left amygdala for a particular contrast, is this the correct version of the commands to run? 1. funcroi-config -seg aseg.mgz 18 -roi <name>.cfg -analysis <analysisname> 2. funcroi-sess -roi <name>.cfg -sf sf.txt -df sesspar 3. funcroi-table-sess -roi <name>.cfg -sf sf.txt -df sesspar -o <name>.txt -c <contrast> -m cespct If I want to extract the average percent signal change from an anatomically constrained functional ROI (e.g. an ROI representing activation in a certain contrast within the lh amygdala), is this the correct version of the commands to run: 4. funcroi-config -seg aseg.mgz 18 -roi <name>.cfg -analysis <analysisname> -contrast <contrast> -sign pos -thresh 1.3 5. funcroi-sess -roi <name>.cfg -sf sf.txt -df sesspar 6. funcroi-table-sess -roi <name>.cfg -sf sf.txt -df sesspar -o <name>.txt -a <analysisname> -c <contrast> -m cespct My questions are (regarding the second set of commands): -in the right hippocampus example under funcroi-config --help, the anatomical constraint is specified with --annot aseg.mgz 53, but it should be --seg aseg.mgz 53 like in my examples, correct? Otherwise you get an error. -Is it ok to use one analysis name in the funcroi-config file and another in funcroi-table-sess? Would that allow me to make an ROI from one analysis and use it to extract signal from another analysis? -If I get a message saying some subjects had "empty ROIs" and the value in the table for them is 0, does this mean that subjects had no activation (meeting the threshold specified) in the first contrast I specified (in funcroi-config) so no ROI could be created from their activation? -If I want to look at activation in more than one anatomical region (for example, bilateral amygdala), is there any way to do that with the -seg option? Pardon the long message. Thanks for the help! Emily

.nii file visualization in tkmedit
by Garikoitz Lerma-Usabiaga 13 Dec '13

13 Dec '13

Hi list, I am trying to visualize a .nii ROI coming from MEG, which is in Colin27 space. I can visualize it perfectly in mricron and tkmedit with the following command: tkmedit -f path/to/spm8/canonical/single_subj_T1.nii -overlay MEG_ROI.nii -fthresh 0.5 (single_subj_T1.nii is Colin27) but when I visualize it with: tkmedit Colin T1.mgz -overlay ./rC_vs_D_band1_0.01_left.nii -overlay-reg /home/glerma/glerma/GIT/bcblscripts/FREESURFER/ROI/Mikel_SingleSubject_to_Colin.dat -fthresh 0.5 -surface lh.white -aux-surface rh.white The result is wrong, and different from the first tkmedit. Should I convert the MEG_ROI.nii ni some specific way to make it work? Any suggestions?

Fwd: qdec analysis with 2 covariates
by Jon Wieser 12 Dec '13

12 Dec '13

Hi Doug, Here's a screen shot, showing the clusters and a scatter plot for one of the 45 clusters. for this dataset, ussualy there is 0 or 1 clusters after monte carlo simulation. i'm not sure if they match one of the 45 clusters in qdec. i'l have to look into that. I would like to have a file which contains data similar to that represented in the scatter plot but for the average of the cluster, not just one vertex, for all of the 45 clusters, values of thickness for each subject. is that possible? I tried running mri_surfcluster, but it only gave me the average data for that clusters, not the individual data. thanks!

Can you send a screen shot of the qdec window when you see 40 clusters? It might be that it is showing clusters regardless of the cluster significance. Do the 3 or 4 clusters created when you run mri_glmfit-sim match clusters in qdec?

which contrast are you looking at in QDEC? Also, what is the voxel-wise threshold in QDEC? The value I gave in the command below is 1.3 but I got that from one of your CSD files.
