Re Re: Checking Surfaces vs. aseg outputs
by Tamara Tavares 18 Jul '16

18 Jul '16

Thank you again Bruce. Since I am primarily interested in ventricular volume, do you think it is necessary to check the the brainmask.mgz for bright or dark spots indicating an intensity normalization error? As well, what about a skull strip error such as removal of brain tissue? I have noticed that sometimes skull strip removes parts of the occipital lobe and I was going to adjust the watershed parameters and re-run recon-all. Do you think this is necessary or would affect the ventricular volume results? Thank you in advance for your help, Tamara

white and pail surface editing
by Ritobrato Datta 18 Jul '16

18 Jul '16

Hi All, We have some subjects who have both wm errors and gm errors. Is the following workflow possible Step 1) control points for the white matter edits. DONT RUN recon-all Step 2) add the pial surface edits. DONT RUN recon-all Step 3) Run recon-all to incorporate control points for wm edits (recon-all -autorecon2-cp -autorecon3 -subjid cp_before) AFTER step 3 is COMPLETE, run Step 4) Run recon-all to create a fixed pial surface (recon-all -autorecon-pial -subjid pial_edits_before) OR Can step 3 and Step 4 be run together as recon-all -autorecon2-cp -autorecon-pial -autorecon3 -subjid cp_before Please let me know. Thanks Ri

Re: [Freesurfer] Freesurfer Digest, Vol 149, Issue 31
by Tamara Tavares 18 Jul '16

Hi Bruce, Thank you for your quick reply. We are primarily interested in ventricular volume but we may look at other areas in the future; this is why I thought it would be a good idea to check the surfaces. Is the reasoning why the surface outputs vs. aseg outputs should be checked is because the surface outputs are used the calculate the structure's volumes? I am fairly new to Freesurfer so I am trying to get a good understanding of it.

Integrate SPM activation maps to FreeSurfer structural volumes
by Mahtab Farahbakhsh 18 Jul '16

18 Jul '16

Dear FreeSurfer, I am trying to register my SPM activation maps to the structural data of each subjects. Except for the commands I could find for the registration, I could not find a guide on the registration of activation maps from SPM to FreeSurfer. Would you please guide me how I should do that? Best Regards, Mahtab.

LME contrasts
by Clara Kühn 18 Jul '16

18 Jul '16

Dear FreeSurfer experts, I am following the mass-univariate (spatiotemporal) model in the LME tutorial. My design matrix X has the following columns: intercept, time, time², group1, group1*time, group1*time², group2, group2*time, group2*time², sex, age, mean_thickness I actually have 3 groups but group1 and group2 in X are dummy coded. I would like to check whether there are group differences in the quadratic term but I don't understand what this command expresses and how the contrast was formed: CM.C = [zeros(3,5) [1 0 0 0 0 0 0;-1 0 0 1 0 0 0;0 0 0 -1 0 0 1] zeros(3,5)]; Could you please explain it on the example design matrix so I can adapt it to mine? Thank you!

Checking Surfaces vs. aseg outputs
by Tamara Tavares 16 Jul '16

16 Jul '16

Hi All, I was hoping to get some help with understanding the surface and aseg volumes. I have some patient's scans and I am interested in examining the ventricular volume but may look at other areas later on. I understand from earlier threads that it is important to check the surface volumes (pial and wm) vs. the aseg output. Why is it more important to check the surfaces vs the aseg outputs if I am interested in getting the volumes? Thank you in advance for your help. Best, Tamara

Re: [Freesurfer] Bug in Freesurfer Installation
by Aman Montazeri 15 Jul '16

15 Jul '16

Im not sure if its the problem or not, but seems that its the file permission error. Either do "sudo su" and re-run your command as root or change the file permissions in /subjects folder. Running commands as "root" is generally not recommended.
