Freesurfer problem on Amazon EC2
by Tawfik Moher Alsady 26 Feb '13

26 Feb '13

Dear Freesurfers, I tried to install freesurfer on amazon EC2 as instructed on the wiki page. Everything went well except that mri_* tools like mri_convert doesn't work. When calling it, it returns nothing.\ I also tried to make another Centos instance and install freesurfer manuall, but the same problem existed. I am trying to use it via ssh (ssh to the server and then enter the freesurfer commands). Any suggestions? And is it fast enough to use FS on Amazon micro instance? On my PC freesurfer takes around 35-40 hours for the whole process. Grazie, Tawfik -- Sent with Sparrow (http://www.sparrowmailapp.com/?sig)

Tkregister2 / Tksurfer / Tkmedit Won't Open
by Daniel Cole 26 Feb '13

26 Feb '13

Hello freesurfers, I just ran registration of my functional images and am trying to visualize the registration for assessment. However, when I use the commands "tkregister-sess -s $SESSIONNAME -d $SESSIONDIRECTORY -fsd bold -funcstem f" or "tkregister2 --targ T1.mgz --fstarg --s $SUBJECTID --surf --mov $FUNCTIONAL_MRI --reg $REG_DAT --plane sag --movbright $MYBRIGHTNESS" the command gets stuck on "Opening window SUBJECT01". I've also tried just opening tksurfer and tkmedit but the terminal produces no output/windows opening and simply freezes. Any ideas to why this could be occurring? I've let it sit at this stage for multiple hours without anything popping up and without any errors. Thanks!

Paula, That seems plenty adequate to run recon-all, so four days to process bert seems odd. Are your energy settings set to goto sleep? The adapter setting should be set to 'never' sleep.

26 Feb '13

Hi freesurfer experts, The output of the segmentation, aseg.mgz only display right hemisphere. I used option -all in the segmentation. How can I make the both hemispheres visible or is there any specific option to choose for segmentation to make both hemispheres visible? Thank you/ Azeez Adebimpe

blend own template into FS pipeline
by Schumman Resonance 26 Feb '13

26 Feb '13

Hi FreeSurfer experts, We are dealing with a sample of children MRI and we want to introduce our own templates into the pipeline instead of the MNI/tailarach. Any advice or guidance you can provide on how to go about doing this would be much appreciate it. Thanks, Kev

Re: [Freesurfer] Registration & segmentation with FSL - obtaining correlation matrix..
by Douglas N Greve 25 Feb '13

First check the value of the BBR cost function. If it is over .8, then something is wrong. To check whether it is an LR flip, you can flip the volume LR and re-run the registration to see if it gets better. doug On 02/25/2013 11:19 AM, Sudhin A.

TRACULA trac-all -path giving 'Segmentation error (core dumped) error'
by Susan Kuo 25 Feb '13

25 Feb '13

Hi FreeSurfer Community, I am trying to run TRACULA's last step, 'trac-all -path -c <path-to-dmrirc-config-script>', and am receiving the error: Segmentation fault(core dumped) Moreover, when I look to standard output (terminal), I noticed that the initial 'dmri_paths' command is incomplete. The terminal shows that the command includes the '--init' switch and several arguments (e.g. '<subject ID>/dlabel/diff/rh.atr_PP_avg33_mni_flt_cpts_5.txt'), the last of which is terminated mid-pathname. Can anyone suggest a reason why this would be the case? Thank you, Susie Kuo

High resolution fMRI and resolution of anatomical scans
by SHAHIN NASR 25 Feb '13

25 Feb '13

Hi, We are planning to collect high resolution *functional* MRI for a group of subjects with voxel size smaller than 1 mm. For these subjects, we already have reconstructed *anatomical *scans with 1 mm voxel size. The question is, do we need to re-collect *anatomical* scans for these subjects with smaller voxel size (e.g. 0.5 x 0.5 x 0.5) or we can still use the old anatomical data for co-registration with freesurfer. P.S.: We usually analyze our subjects in native space but technically we can do this in fsaverage space. So, we only need this co-registration for pre-processing and mapping fMRI data to fsaverage space.

creating figures using f-score color scale
by Maria Jalbrzikowski 25 Feb '13

25 Feb '13

Dear Freesurfer experts, I was wondering if you could help me in figuring out how to create a figure in tksurfer. A recent publication in PLoS One on William's Syndrome showed a figure with a color scale for the F-scores and reflected the F-values through colors that they obtained in ROI analyses. Does anyone have any suggestions for how they created this figure? I wrote the authors of the manuscript, but have not yet heard back. I would like to make a similar figure for some analyses I've recently run. I've attached a picture of the figure and the title of the article is Regional Brain Differences in Cortical Thickness, Surface Area and Subcortical Volume in Individuals with Williams Syndrome by Shashwath A. Meda, Jennifer R. Pryweller, Tricia A. Thornton-Wells Thank you for your help! Best, Maria Jalbrzikowski -- Maria Jalbrzikowski, M.A. University of California, Los Angeles
