Re: [Freesurfer] Hippocampal segmentation doubts
Thank you so much for your answer Koen,I understand, but now I'm having some trouble when running the command on one subject, hope you can help me.I have tried to perform the hippocampal subfields segmentation by running:recon-all -s MySubject -hippo-subfields and also:kvlSegmentHippocampalSubfields.sh MySubject left /root/trabajo/freesurfer/subjects /root/trabajo/freesurfer/subjects/MySubject/tmp/subfieldResults But I always get the following error:maximalDeformation: 75.1793Transforming meshDone transforming meshRasterizing Levenberg-Marquardt...numberOfEntries: 24131/root/trabajo/freesurfer/bin/kvlSegmentHippocampalSubfields.sh: line 18: 23175 Segmentation fault kvlSegmentWithoutGUI configurationFileDeformableRegistration.txtfailed to do kvlSegmentWithoutGUI configurationFileDeformableRegistration.txtLinux localhost.localdomain 2.6.9-34.ELsmp #1 SMP Thu Mar 9 06:23:23 GMT 2006 x86_64 x86_64 x86_64 GNU/Linuxrecon-all -s MySubject exited with ERRORS at Tue Jul 3 15:54:39 CEST 2012For more details, see the log file /root/trabajo/freesurfer/subjects/MySubject/scripts/recon-all.logTo report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReportingThe recon-all.log says:##@# Hippocampal Subfields processing Tue Jul 3 15:48:33 CEST 2012 mkdir -p /root/trabajo/freesurfer/subjects/MySubject/tmp/subfieldResults kvlSegmentHippocampalSubfields.sh MySubject left /root/trabajo/freesurfer/subjects /root/trabajo/freesurfer/subjects/MySubject/tmp/subfieldResults Linux localhost.localdomain 2.6.9-34.ELsmp #1 SMP Thu Mar 9 06:23:23 GMT 2006 x86_64 x86_64 x86_64 GNU/Linuxrecon-all -s MySubject exited with ERRORS at Tue Jul 3 15:54:39 CEST 2012To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting This error occurres only on this subject and for the left hemisphere, not like this for the right hemisphere, which ends perfectly when running the second command.

Using pre-processed data obtained with an older version ofFreeSurfer should be OK, as long as you remember that the obtainedresults might/will be different from the ones you'd get if you had runthe whole analysis from scratch.2. The generic label hippocampus is used to denote the tail of thehippocampus, where no attempt is made to further subdivide between thedifferent subfields. This is admittedly not a great naming convention- sorry for the confusion.3. You should not do any correction on the obtained volumes: partialvolume here merely means the effect of voxels containing a mix ofdifferent subfields simultaneously. The non-partial volume resultshere only indicate that this effect is not explicitly modeled when youcall the hippocampal subfield segmentation routine with its defaultsettings.Hope this helps,KoenOn Thu, Jun 28, 2012 at 5:29 AM, Gabriel Gonzalez Escamillaggon...@upo.es wrote: Dear Freesurfer experts I'm starting to deal with the FS v5.1 hippocampal subfields segmentation, and I have a couple doubts...

As for improvements of em_reg, I'll try to split each transform as well as parallelize the energy evaluation. Parallelising the energy evaluation is the lowest hanging fruit, and is what happens in the 'slow' GPU version. But for highest performance, I would convert the nested transform loops into a single one, and farm those out between OpenMP threads (I wouldn't bother trying nested parallelism of the energy evaluation, although you might want to do some SSE tinkering). That is effectively what happens in the 'fast' GPU version - you can use the same basic structure. But be aware that the slightly different transforms which result can cause you to converge to a different solution.

[Freesurfer] multiple correction
Hi, all, I have some questions about the multiple correction in qdec. I performed group analysis using qdec.

And if I use monte carlo null-z simulation, I have to pre-run mri_glmfit-sim 1?

[Freesurfer] overlapping labels
Hi freesurfers, Can a .annot file include labels with overlapping vertices? If not, then when using mris_label2annot, how does freesurfer decide which label to assign the vertices to?

Re: [Freesurfer] TkSurfer and new color table. Mislabelling
Hi Pedro, Have a look at this article: http://brainder.org/2011/07/05/freesurfer-brains-in-arbitrary-colours I think this is the same you'd like to do (or you can change some steps easily). Hope it helps!
