Label to ROI volume
by mmoayedi＠uhnres.utoronto.ca 30 Jul '12

30 Jul '12

Dear FS Experts, I have run recon-all on my subjects. I'm looking to convert the V1 and various BA labels to ROIs in 3D anatomical space (orig.mgz). How would I convert my freesufer label files to ROIs. Thank you! Massieh Moayedi

Non rigid registration
by SHAHIN NASR 30 Jul '12

30 Jul '12

Hi, In our functional MRI studies, we co-registration the functional images to anatomical scans (a part of preproc-sess routine in version 5) before measuring the contrasts. But for one of our studies, a reviewer has asked if a “non-rigid image registration” would change results when we are assessing activity within artifact-prone brain areas (e.g. anterior temporal areas). As far as I know, freesurfer registration works fine and even in this study, we have found very strong activity/contrast within anterior tempotal lobe. But I was wondering whether you have tested this possibility or not. If yes, then I appreciate if you can introduce me a reference (published article) to support our answer. Regards -- Shahin Nasr PhD in Cognitive Neuroscience Martinos Imaging Center, MGH Harvard Medical School

Hi, I recently install Freesurfer under ubuntu. I tested two own data. It works in one our own case, but did not work for other cases. The problem is the Freesurfer "not found or unknown file type for file /home/d4201z/Desktop/im_4/20001108150735000005086.dcm" when convert convert dcm to mgz. Any helps are appreciated!

recon-all
by Susan Alice McLaughlin 30 Jul '12

30 Jul '12

Hi Freesurfer experts, We’ve been collecting structural (1mm isotropic) and functional (2.75x2.75x3mm) data on a Philips 3T scanner using an 8-channel head coil. We are reconstructing each subject’s surface and mapping functional data processed in FSL’s FEAT to the surface. For some subjects, we have only 1 MPRAGE, but for others, we have multiple (2 or 3) MPRAGEs, acquired in separate scanning sessions. Looking back at the list serve and FSLwiki (http://surfer.nmr.mgh.harvard.edu/fswiki/FsQuizAnswers) it appears that our SNR should be good enough that we do not need -- and perhaps SHOULD NOT use --multiple MPRAGEs when using recon-all. Is there general agreement on this? How does one go about quantitatively comparing one surface reconstruction derived from 1 MPRAGE to another derived from 2 MPRAGEs? Thank you, Susan McLaughlin Doctoral Candidate SPACE Lab (Stimulus-Parametric Imaging of Auditory Cortex) Dept. of Speech and Hearing Sciences University of Washington

Thickness and variable plot in glmfit
by Jeni Chen 30 Jul '12

30 Jul '12

Hello again, In Qdec we get a plot of the data for a particular vertex showing the variable and the thickness in the x, y axis respectively. Is there a way to get the same plot when using glmfit? Where do I find the data for the plot? Thank you! Jeni Chen

Hi Jeni, you should not smooth with both. If you want to smooth within a given label with surf2surf, pass that label to surf2surf then don't smooth with glmfit. doug On 07/30/2012 12:46 AM, Jeni Chen wrote: > Hi Doug, > > When you say "If you smooth using surf2surf, then do not smooth using > glmfit..." are you referring to smoothing the whole hemisphere, or > with a label?

Hi Doug. The missing files are NOT in $FREESURFER_HOME/bin; So, I guess that's why they are not found even though the path is set up in the system PATH variable. Suggestions? Fidel Are the missing files in $FREESURFER_HOME/bin and is that path in your system PATH variable?

Re: [Freesurfer] Smoothing in -qcache and the -fwhm option in mri_glmfit
by Douglas Greve 30 Jul '12

Hi Jeni, usually you smooth with surf2surf and include a mask or label to indicate that it should only be smoothed inside the mask/label. mri_glmfit will create a mask from non-zero voxels; if you ask glmfit to smooth, then it will only smooth inside of the mask. If you smooth using surf2surf, then do not smooth using glmfit. doug On 7/29/12 11:49 PM, Jeni Chen wrote: > Now I'm confused...

So essentially the -fwhm option in mri_glmfit does the same thing as mri_surf2surf --fwhm ? Just want to make sure... Thanks again! Jeni

converting to mgz error
by Skyler Gabriel Shollenbarger 29 Jul '12

Hi, Trying to convert a file to mgz and keep getting a 'document file' instead of the freesurfer mgz file. This is the command I used: mri_convert -ot mgz XXXXXXXX-anat+orig.BRIK freesurfer/mri/orig/001.mgz Any suggestions? Thanks! Skyler -- Skyler G.
