[Freesurfer] open *.mgh
Hi, Thank you for your help before. And, I have a problem today. How do I open the file called *.mgh as F.mgh and sig.mgh in the dictionary “qedc”? This problem has been nagging me for some time.

[Freesurfer] thickness value
Hi, I gain the cortical thickness value and other information of all ROIs for all my subjects (found in $FREESURFER_HOME/subjects/filename/stats). But, can I gain the cortical thickness value and other information of all vertices for all my subjects? I want to gain the values, not maps. Thank you in advance!

[Freesurfer] mri_convert
Hi, I am finished to run my subjects using recon-all and I would like to know the usage of mri_convert to convert the results of FreeSurfer into the analyze format or nifti. Some of the results of FreeSurfer are volumes (e.g. brainmask.mgz) and some of them are surfaces (e.g. lh inflated). What can I do to convert these formats to analysis format or nifti?

[Freesurfer] segmentation
Hi, I have some problem. Could you get me some suggestion? I get a simulation brain with no-adding noise from BrainWeb. Then, I add 1% noise and 5% noise, respectively, to the simulation brains. When I finished these simulation brains through FreeSurfer, I found that the cortical thickness of these two groups (1% vs 5%) has a bias. Would you get me some comment? I guess the finding of bias maybe has a great relationship with the process of segmentation. Would you tell me what to do segmentation in FreeSuefer? Thank you in advance!

Re: [Freesurfer] make_average_subject error about limit
Hi, I copied the default average subject from $FREESURFER_HOME/subjects dir to my analysis dir. Then, I make a FSGD file and some contrast matrices and put them into my analysis dir. After that, I start to run group analysis. But, when I type the following commands: mris_preproc --fsgd noise_0.5-1-5.fsgd --target fsaverage -- hemi lh --meas thickness --out lh.noise_0.5-1-5.thickness.00.mgh The terminal shows: ERROR: flag -- not recognized Now, I have two problems want to ask. 1) What's wrong about the commands that I type? And, how to solve the problem? 2) I found this commands from the FreeSurfer web. And, I'm confused about that two ways to do analysis. One is cached (qcached) data, and the other is uncached data. What's way is suitable to my subjects? (My subjects is one factor and three levels, had run QDEC before, but QDEC is not good job to analysis, and, I want to change the analysis method from QDEC to DODS) So, which way do I choose to analysis my subjects?? Idon't understand the differences from them. Thank you in advance!

Re: [Freesurfer] image matrix
Hi,
Thank you for your response! But, I can’t find vertices number of a
surface through typing the following command:
mris_euler_number noise0.5_0
When I type the command, the terminal shows some information as follow.
euler # = v-e+f = 2g-2: 0 - 0 + 0 = 0 --> 1 holes
F =2V-4: 0 != 0-4 (-4)
2E=3F:0 = 0 (0)
total defect index = 2
But I don’t know what meaning of the numbers is. Would you tell me?
And, have any other ways to get the vertices number of a surface?
Then, I want to make sure that is image matrix 256 x 256 x 256?
Thank you for in advance!!

Re: [Freesurfer] image matrix
Hi,
Thank you for your response! I use the command what you said.
The terminal shows:
euler # = v-e+f = 2g-2: 154901 - 464697 + 309798 = 2 --> 0 holes
F =2V-4: 309798 = 309802-4 (0)
2E=3F:929394 = 929394 (0)
I guess that 929394 is the vertices number of surface which I want to get.
Right? If not, which value is I want to get?
Then, I run lh.orig and another subjects, I find the value is different from
those. So, the vertices number of surface is not a fixed value and changes
with hemispheres and subjects.
Thank you in advance!!

So I open tksurfer to check. But, I found the vertex Tal coordinate of lh.thickness.asc is different from the shows of terminal. Have something wrong of these commands? Thank you in advance!

[Freesurfer] ascii file
Hi, I have two problems want to solve. First, I want to know what coordinates it is, when I type the following command. mris_convert -c lh.thickness lh.white lh.thickness.asc Is it Tal coordinate?? Second, if the asc file doesn't use Tal coordinate, what commands do I type to obtain ? Bcause I really want to get the thickness asc with Tal coordinate. Thank you in advance!

Hi, I had asked two problems before; one is what is coordinates when I type mris_convert -c lh.thickness lh.white lh.thickness.asc, and another is if the asc file doesn't use Tal coordinate, what commands do I type to obtain the thickness asc with Tal coordinate?, and then you responded me with “the coordinates are native RAS. You can use mri_surf2surf to convert the surface to tal coords with the talairach.xfm.” So, first, I change the native RAS cooridinate to Tal coordinate with “mri_surf2surf --srcsubject noise0.5_0 --srcsurfval thickness --trgsubject noise0.5_0 --trgsurfval noise0.5_0_tal.xfm --hemi lh --sval-tal-xyz orig --tval-xyz” srcsubject = noise0.5_0 srcval = thickness srctype= trgsubject = noise0.5_0 trgval = noise0.5_0_tal.xfm trgtype= surfreg= sphere.reg srchemi= lh trghemi= lh frame = 0 fwhm-in= 0 fwhm-out = 0 Reading source surface reg /usr/local/freesurfer/subjects/analysis/noise_analysis//noise_0.5_1_5//noise0.5_0/surf/lh.sphere.reg Loading source data Reading surface file /usr/local/freesurfer/subjects/analysis/noise_analysis//noise_0.5_1_5//noise0.5_0/surf/lh.orig Applying MNI305 talairach transform 0.966 0.002 -0.004 0.426; 0.018 0.989 0.041 -19.382; -0.006 0.032 0.962 17.438; 0.000 0.000 0.000 1.000; INFO: surfcluster: NOT fixing group surface area INFO: trgsubject = srcsubject Saving target data Then, I obtain the thickness asc file with Tal coordinate using this command “mris_convert -c lh.noise0.5_0_tal.xfm lh.white lh.thickness.asc” But, this has an error: MRISreadBinaryCurvature: incompatible vertex number in file ./lh.noise0.5_0_tal.xfm What’s wrong?

[Freesurfer] thickness map
Hi, I have some problems want to understand. (1) I want to analysis the cortical thickness difference of three groups. But, three groups (one factor/three levels) of Freesurfer is not satisfied with our demand. Because we want to get a thickness difference map that satisfied with the many voxels containing A group > B group > C group and A group < B group < C group, Freesurfer can’t do that. So, we want to get this map by myself and use Matlab or other tool to obtain that. And, now I want to obtain a file that containing the Tal coordinate and the thickness value of this coordinate for all subjects. Would you tell me how to get the file that containing the Tal coordinate and the thickness value of this coordinate? (2) Before, I want to use the following command to get the thickness value. The command line is "mri_surf2surf --srcsubject noise0.5_0 --srcsurfval thickness --sfmt surface --trgsubject noise0.5_0 --trgsurfval noise0.5_0_tal.xfm --tfmt surface --hemi lh --sval-tal-xyz orig --tval-xyz", and then i type “mris_convert lh.noise0.5_0_tal.xfm lh.white lh.thickness.asc”. But, the result file(lh.thickness.asc) does not contain the thickness value of this coordinate. So, I think these commands have some error. (3) Use the command “mris_convert –c lh.thickness lh.white lh.thickness.asc” to obtain the thickness value of the RAS coordinates. But, I’m confused about that if I change lh.white to lh.pail or lh.inflated. What’s difference for the three? (4) And, I ask some problem before. Everyone said the result file(lh.thickness.asc) is using RAS coordinates through “mris_convert –c lh.thickness lh.white lh.thickness.asc”. But, I have confused about this. When I open this subject by tksurfer, I look at the coordinate of the vertex RAS in the tksurfer tool box, and the coordinate is difference from the coordinates that obtain from the command “mris_convert –c lh.thickness lh.white lh.thickness.asc”. So, which one is right? Thank you in advance! Feng-Xian ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
Re: [Freesurfer] thickness map
Hi, Thank you for your responses before. I have another problem want to solve. I check the number of vertex for all subjects, but I found that the number of vertex for each subjects and each hemispheres is different. Because I want to compare cortical thickness using vertex-by-vertex, I would to obtain the same vertex number. Therefore, have something to do to obtain the same vertex number, i.e. template the cortical thickness at each vertex for each subject on the fsaverage surface, or other methods? How can I do? Would you get me a hand? Thank you in advance!

Then I obtain F value and p value of anova analysis using MATLAB. Now, I want to map the results of anova to fsaverage. Could these values do that? Or, you could recommend me another way to obtain the same map. Thank you in advance! Feng-Xian 2009/10/1 Bruce Fischl > Hi Feng-Xian > have you run recon-all on your anatomical data?

Re: [Freesurfer] map .xls or .txt file to fsaverage
Hi, They have the same coordinates. Before I run MATLAB to obtain the analysis of anova, I mapped the cortical thickness value of each subject to fsaverage using mri_surf2surf and then I obtained the asc file with the coordinates of 65536 vertices and their thickness value. Now, I want to map the results of anova to fsaverage. Could these results do that? Or, you could recommend me another way to obtain the same map. Thank you in advance!

Re: [Freesurfer] map .xls or .txt file to fsaverage
Hi, Thank you for your suggestion. But, I run the MATLAB under windows XP, because I can’t setup the MATLAB under LINUX. I don’t know what’s wrong, and now I only run MATLAB under windows XP. So, when I did anova command to obtain F value and p value using MATLAB under windows XP. I save these values in xls format. Then, I would like to map F value and p value to inflated surface of fsaverage, respectively. Could you tell me how to do and what command do I type? And, what’s the functional volume?

After running the qdec and analyzed my data(cortical thickness), I display a plot of the data for a particular vertex by left-clicking on a point while holding down the Ctrl key. It shows a plot and its plot window shows this vertex's *surface coordinates.* 1) Does the surface coordinates differ from Talairach coordinates? 2) If yes, can I translate the surface coordinates to Talairach coordinates? And how do I do? Does Freesurfer have some methods to do that? Thank you in advance.
