mri_glmfit-sim for interhemispheric comparison
by Shigetoshi Takaya 11 Dec '12

11 Dec '12

Hi Doug, I did surface-based inter-hemispheric comparison. I used an arbitrary surface data (.mgz) resampled from a volume data (.nii), otherwise I follow the instruction. <http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi> http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi I got a good result for mri_glmfit. But when I run mri_glmfit-sim, the following error messeage popped up. ERROR: cannot find $FRESURFER_HOME/average/mult-comp-cor/fsaverage_sym/lh/cortex/fwhm00/abs/th2 0/mc-z.csd I did not find "fwhm00"anywhere in the downloaded file "mult-comp-cor", although I found fwhm01-30 directories. Am I missing somethine? Thank you very much in advance, Shige

Sorry if I bother you again, actually I would like to convert from 256,128,256 to 256,256,256 and from 181,145,181 to 256,256,256. Can you tell me the complete command and not just the option. -rl <volume> if volume is 256,256,256? thank you vary much Andrea ----Messaggio originale---- Da: fischl(a)nmr.mgh.harvard.edu Data: 10-dic-2012 14.36 A: "Andrea Tateo"<andrea.tateo(a)virgilio.it> Cc: <freesurfer(a)nmr.mgh.harvard.edu> Ogg: Re: [Freesurfer] convert size Hi Andrea I think there is a typo in your email as your sizes are the same. If you have a volume you would like to reslice it like you can use the -rl <volume> option to do what you want. cheers Bruce On Mon, 10 Dec 2012, Andrea Tateo wrote: > Hello FS experts, > I would like to to convert binary images from size 256,256,256 voxels to > size 256, 256, 256. > > Is there any FreeSurfer's module to make it? > > Thank you very much > > Andrea > > The information in this e-mail is intended only for the person to whom it is addressed.

Thank you so much! All (?) makes sense now that I am looking at the log files. It has actually only processed 6 (out of 102). Now I am trying to figure out why it skipped the ones it did best wishes, Prerona On 10 December 2012 20:33, s0675204 <s0675204(a)sms.ed.ac.uk> wrote: > okay. i will look through the logs for all the subjects and check! > Thanks so much > > best wishes, > > Prerona > > > On 10 December 2012 20:00, Anastasia Yendiki > <ayendiki(a)nmr.mgh.harvard.edu> wrote: >> >> Which subject was running at the time?

Hello My trac- preproc has completed. However, I am confused about the status message. It says: #------------------------------------- trac-preproc finished without error at Mon Dec 10 16:32:20 EST 2012 ERROR: cannot find /home/canlilab/SBU/data/recon_output/00387 Does this mean it was completed succesfully for everyone or everyone but that 00387 person?

color bar question again
by Longchuan Li 10 Dec '12

10 Dec '12

Hi, FreeSurfer experts I am sorry to bother again, but it seems that my color bar issue is still not solved. I was told last time that the reason for the minimal values in the color bar not properly shown is probably because their values were too small. However, when I display two other overlay files (see attached), I still notice that the minimal values are not properly shown in the color bar either. Is there any function in the overlay display that I am missing to have this mismatched color bar? Many thanks in advance! Longchuan

Re: [Freesurfer] Longitudinal analysis - contrast

Hi Jorge, Thank you very much !! It worked !! I used the new versions: /lme_mass_F1; lms_mass_fit1 /and/lme_mass_fit_vw1/, which you sent me for the old Matlab. Additionally, I uploaded in Matlab - /lme_fit_init; lme_FSfit; lme_Gradient; vec; lme_E1/; /fs_write_fstats; fs_write_Y;/ it ended with: "/Algorithm did not converge at 0 percent/" I suppose this means everything went fine. Total time - 90 minutes. /fstats/ - finished OK /fs_write_stats/ - finished OK. I opened the sig.mgh and the results are ok ! :) Thank you very much for your support Jorge !! Have a great week !

which step comes first
by Catherine Bois 10 Dec '12

10 Dec '12

Hi, when reconstructing the brains including manual edits, does the step that incorporates control points "come before" the white matter edits? Ie so if I do both control points and white matter edits, will the white matter edits be take into account even if I just use -autorecon -cp , and not -wm? Thanks

nuisance variable ICV
by Berg, S.F. van den 10 Dec '12

10 Dec '12

Hi Freesurfer Experts, Just to make it sure i have a question about correcting for cranial size. I compared two groups, 100 patients versus 50 Controls. I entered a discrete variable 'groups' (Patients: 1 and controls:2) in qdec. For cortical thickness difference between these groups, do i have to control for total intracranial volume? ICV (intra cranial volume is output from aseg2tables) or controlling for another variable which estimate total brain volume, like total gray matter or supra tentorial volume? In my correlation analyses, relating cognitive peformance and cortical thickness within the patient group. Do i have to control for ICV or Total gray matter? besides the variable age, gender and education. I think only volume differences between groups need controlling for ICV, is that correct? And in my correlation analyses, relating cognitive performance ato subcortical volume within the patient group. Do i have to control for ICV or Total gray matter? besides the variables age, gender and education. Do you have a reference to a methodological paper, which descibes different (anatomical) nuisance factors and their influence on the data? Is there a automated correction for brain size in the cortical and subcortical freesurfer stream (step of recon -all command)? Many Thanks, Stan

Re: [Freesurfer] abblocked documentation?
by Douglas N Greve 10 Dec '12

Hi Summer, there is some documentation in mkanalysis-sess -help. It's not very much documentation, so I just wrote a little bit more which I have included below. Let me know if you still have questions. doug -abblocked PeriodSec Design is AB-Blocked (ie, periodic, two condition). Specify the period of stimuluation in seconds (NOTE: in previous versions you had to specify the number of cycles). No paradigm file is required. When selxavg3-sess is run, it will automatically create a Fourier analysis with components at the fundamental and first harmonic as well as components at a frequency just below and above the fundamental for a total of 4 frequencies each of which will have a real and imaginary component for a total of 8 regressors. It will also create a contrast called "fund" (for "fundamental"). This contrast will be a F-contrast to test both the real (cosine) and imaginary (sine) components of the fundamental frequency with the fsig volume being the final result. There will also be other files there including real.nii and imag.nii which are the real and imaginary components. There will also be angle.nii and angle.masked.nii which will be the angle between the real and imaginary; the masked version will be masked by fsig > 2.
