ocn.nii & ocn.annot mismatch
by Tuominen, Lauri Johannes 28 Feb '17

28 Feb '17

Hi all, Has anyone encountered a mismatch between the ocn.nii & ocn.annot files. I'm doing a fsfast group analysis with freesurfer5.3 and the ocn.nii file is missing one region that comes up in all the other files as well as in the annot. A fix for this would be much appreciated. Please see the attachement Cheers! Lauri Tuominen

How to output particular area from stats subdir
by Jing Gu 28 Feb '17

28 Feb '17

Dear FreeSurfer Developers, By using the following code, we can get volume data of different areas from stats file. asegstats2table --subjects N01 --meas volume --tablefile aseg_stats.txt How can I get information of one or two areas, such as hippocampal? thanks Best, Gina

chose between 5.3 and 6.0
by ? ? 28 Feb '17

28 Feb '17

dear FS community: now i have more than 200 subjects which already finished recon-all with 5.3, since 6.0 released, i wonder should i re-run them with 6.0 as lots of changes like different surf-map and registration. i ran a bit of them as test and i found the pial problems were more than 5.3, and it seems some subcortical structures were vanished in the brainmask.mgz, though the aseg.mgz looked good. i wanna ask is my problem serious or it is usual with 6.0, and which version you think is better for cortical volume and surface thickness reserch? best regards weiwei west china hospital ________________________________ weiqi77777(a)live.com

Re: [Freesurfer] editing topological defect
by Antonin Skoch 28 Feb '17

28 Feb '17

Dear Shane, the "topological defect" in FreeSurfer jargon means that the estimated surface contains errors like "holes" or "handles". See PPT from FreeSurfer course http://surfer.nmr.mgh.harvard.edu/pub/docs/freesurfer.failure_modes.ppt or https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TroubleshootingData XL (=extra large?) defect often means large error in previous steps of recon-all, usually skullstrip or white matte segmentation. In some cases the error is automatically corrected, but not always. To see, what is happening, I would suggest to inspect brainmask.mgz or wm.mgz and correct errors. You can also find more information on the forum, there are quite large amount of posts related to topological defects. For example: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg30763.html Antonin Skoch Hi Freesurfer Team, I am running recon-all on Freesurfer version 6. A few of my subjects have “XL defect detected …” and their recon-all have been running for more than 20 hours. I hope this is not a silly question, but will this XL defect be corrected eventually…? Another question, what are “defects”? Is there anything I could do to the raw T1 before recon-all? Thanks! Shane

wm editting doubt
by Manuel Delgado 28 Feb '17

28 Feb '17

Hello all, I have a basic question regarding the wm edition. As you can see in the images attached, the white matter mask includes the ventricle in one side but excludes it in the other. My question is: do I have to draw the voxels that are excluded from the white matter mask? I apologize if this issue has been previously raised. Best, Manuel

Re: [Freesurfer] ACPC alignment before or after running on Freesurfer?
by Antonin Skoch 28 Feb '17

28 Feb '17

Dear Kristine, I am currently experimenting with prepending PreFreeSurferPipeline.sh to recon-all (of HCP pipelines https://github.com/Washington-University/Pipelines ) which does APCP alignment, robust FOV (cropping of unrelevant parts of image FOV - neck etc.), bias correction and (optionally) FNIRT-based skullstrip and gradient nonlinearity correction. I believe that ACPC alignment could prevent Talairach registration errors/inaccuracies in recon-all which could have profound effect on subsequent skullstrip and subcortical labeling (it could at least prevent to disastrous errors which some other users reported recently, such as this: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg51789.html) This could also help to mutual registration of data of multiple sessions (i.e. in longitudinal studies) to compensate different head positioning. It could be also beneficial to use FNIRT-based skullstrip to help (or even to replace) freesurfer's skullstrip (as is it done in FreeSurferPipeline.sh of HCP pipelines), since, to my experience, the inaccurate skullstrip is basis of most errors in FreeSurfer reconstruction stream. This FNIRT skullstrip works fine with our high-quality data from 64-channel coil acquired by protocol similar to Human connectome project (I ocasionally find only several, probably negligible amount of voxels of gray matter cut-out), but not as good with older data where significant parts of gray matter are often cut-out. The drawback is that when you want to get to the original space, you have to account one more transformation and there is one more step in processing pipeline you need to check. This is my view based on current experience. I would also greatly appreciate any comment (different perspective) of other users. Regards, Antonin Dear Freesurfer team, This may sound like a bit of a small question, but I could not find any exact answer elsewhere.Does the exact orientation of the input image have much effect on the accuracy of the segmentation in Freesurfer? It seems that some people apply ACPC alignment to the output of Freesurfer, so I am confused as to which order would be optimal. Thank you in advance, Kristine

Manual edit to include missing cortex?
by Rockers, Elijah D. 27 Feb '17

27 Feb '17

Is there something I can do to extend the pial surface to include cortex that it ignored? In some places there are rather large chunks of cortex not included in the pial surface. http://imgur.com/a/FnAgj Link is to a screenshot, notice the top of the brain. It's fairly pronounced, visible in 12 adjacent sagittal slices. I tried using the "Reposition Surface" tool, but I'm not exactly how it works, and I ended up just making the surface look crazy there. I also tried adding control points in the white matter near the edges of the WM surface by the problem and ran the reconstruction, as someone in the archives suggested, but it didn't change the surface. Thanks for your help, Eli Houston Methodist. Leading Medicine.
