editing pre-existing annotations
by Eric Feczko 09 Nov '06

09 Nov '06

Hey, Is there a way to add structures/labels to a pre-existing annotation file? I sampled an annotated atlas onto a subjects surface. But when I load the annotation and try to create a new label, I can't export the edited annotation without eliminating the new label. I tried to create a new color lookup table with the new structure included, and I can load the table in tksurfer just fine. However, when I also try to import the pre-existing annotation(in order to edit it), the color table existing in the annotation overrides the color lookup table I load. If it try to load the table after importing the annotation, the new structure/label does not show up in the label window. If anyone can help me with this issue, that would be great, thanks! -Eric

Question

Hello, my name is Wan Park and I am working at Columbia University. After converting General Electric DIACOM files into COR, I go to the Setup Structural Scans. There I set the Structural Scan Dir and then Convert/Average. After that, Start the Process Volume, but it seems that there is a problem when it tries to strip the skull. i receive this message: Images (brain): /Users/../Volumes/ste/freesurfer/subjects/scott/mri/brain/COR-001.. not found ... strip skull first So I go to see the logs and I find this: /Users/wanpark/Desktop/FreeSurfer/freesurfer/bin/Darwin/mri_normalize /Users/../Volumes/stem/freesurfer/subjects/scott/mri/orig /Users/../Volumes/stem/freesurfer/subjects/scott/mri/T1 reading from /Users/../Volumes/stem/freesurfer/subjects/scott/mri/orig... normalizing image... 3d normalization pass 1 of 2 building Voronoi diagram... performing soap bubble smoothing... 3d normalization pass 2 of 2 building Voronoi diagram... performing soap bubble smoothing... writing output to /Users/../Volumes/stem/freesurfer/subjects/scott/mri/T1 3D bias adjustment took 3 minutes and 23 seconds.

retinotopy and FsFast
by Jane Aspell 17 May '06

17 May '06

Hi Thanks for all your previous help with freesurfer. I am trying to use FsFast to do retinotopy analysis and have been following the instructions at: https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis I come undone at the stage of running the actual analysis, where the command should be: >sfa-sess -s avdk -a rtopy what does 'avdk' refer to? when i run it i get: ERROR: could not find session avdk when i try it with the arguments: >sfa-sess -analysis rtopy -sf sessid which is similar to the arguments needed for 'selxavg-sess' i get a similar error of not been able to find my (particular subject's) session. i believe i have set up the all the directory structures etc correctly for the sessions format as previous steps worked fine. any ideas what's going wrong? thanks Jane Aspell

Hi I would be really grateful if someone could help me with the problems I am having with mk-fieldsign. Even after installing a new version of freesurfer and making various changes to libraries etc. when i run: "paint-sess -sf sessid -a rtopy -hemi rh" i get the error below: tksurfer: run tcl script: mk-fieldsign.tcl couldn't read file "mk-fieldsign.tcl": no such file or directory even though mk-fieldsign.tcl is in the same directory as tksurfer.tcl (which works fine). i am running Red Hat Linux release 9 (Shrike) and installed from freesurfer-Linux-rh9-v2.2.tar.gz any idea what to do? thanks again for your help!

3T problems
by Fornito, Alexander 30 Apr '06

30 Apr '06

Hi, I'm trying to segment some Siemens 3T images (200x200x256; 1mm3) and have encountered some problems at autorecon1 - the normalization seems to label some of the background as white matter. Needless to say, the skullstrip fails spectacularly. I've attached a snapshot of the T1 image showing the problem.Any ideas as to why this might occur? I'm running recon-all version 1.104 Thanks, Alex Alex Fornito M.Psych/PhD (clin. neuro.) candidate Melbourne Neuropsychiatry Centre and Department of Psychology National Neuroscience Facility The University of Melbourne Levels 2 & 3, Alan Gilbert Building 161 Barry St Carlton South Vic 3053 Australia Ph: +61 3 8344 1624 Fax: +61 3 9348 0469 email: alexander.fornito(a)wh.org.au

Skullstripping
by Joao Pereira 29 Apr '06

29 Apr '06

Can someone explain me why my the recon-all skull stripping option is writting a file named brainmask.mgz instead of brain.mgz? This is a problem because the subsequent procedures do not recognize the file. Thank you! JP

Surface intersections
by rhaynes＠neuro.gatech.edu 28 Apr '06

28 Apr '06

After running the final processing stage of recon-all, I viewed the results in tkmedit and noticed several places where the wm and pial surfaces intersect (see attachment). This mostly happens on the medial and temporal areas, but I have seen it elsewhere. Doesn't this cause problems with the cortical thickness estimation? Is there anything else I should be doing to correct this? Thanks. Ryan

display conventions
by adam walczak 27 Apr '06

27 Apr '06

Hello, I was wondering if FreeSurfer needed the data to be in a specific display convention (neurological or radiological). I have to do some manipulation of our images in order to get them in the correct space and was wondering if the program needed the data in a specific display type to work properly. I noticed that tkmedit displays in the radiological convention. Thank you, Adam adam --------------------------------- Yahoo! Messenger with Voice. PC-to-Phone calls for ridiculously low rates.

Hello, I have just installed FreeSurfer and I can't run csurf. The GUI appears but it is useless, giving an error at the beginning saying it can't find the paint file in the bin directory. Even when I select the bert subject, nothing happens, requiring COR files to exist. Could you please help me qith this? Thank you, Joao Pereira
