Hello all, Using the most updated version of freesurfer, I ran autorecon3 on a set of data obtained with an old version of the software (the first version) and I obtained the following error message: Loading rh annotations from /home/chiuan/freesurfer/subjects/becker2ANNIE/label/rh.aparc.annot Have color table for lh white annotation Have color table for rh white annotation Loading lh ribbon mask from /home/chiuan/freesurfer/subjects/becker2ANNIE/mri/lh.ribbon.mgz ERROR: loading aseg /home/chiuan/freesurfer/subjects/becker2ANNIE/mri/lh.ribbon.mgz Linux mushrat.ninds.nih.gov 2.6.9-42.0.2.ELsmp #1 SMP Thu Aug 17 18:00:32 EDT 2006 i686 i686 i386 GNU/Linux recon-all exited with ERRORS at Wed May 16 22:24:13 EDT 2007 Could someone please clarify? Thanks in advance, Annie

Temporal derivative in mkanalysis-sess
by Dan Dillon 16 May '07

16 May '07

Dear FreeSurfers, I'd like to add a temporal derivative to my gammafit model and understand that this can be done using mkanalysis-sess. However, I can't seem to track down the relevant flag (using -help or the wiki). Can someone point me in the right direction? Thanks! Dan Dillon

Grey matter issue.
by Kt Labadie 16 May '07

16 May '07

Hello. I have attached an image of a case I am working that I can't figure out how to fix. I have approximately 15 cases like this, so any suggestions would be helpful. You can see that some grey matter is not being included along the left and right sides. It is like this for about 30 slides. I did a few things to try and fix it, but nothing worked. I adjusted the watershed number to 30 and it just included the entire skull and did not expand the surface out. I also used the -atlas and -more commands to try and adjust the surface, but it did not shift. I also checked the Talairach registration, but it was fine. Any suggestions? Thanks KT LaBadie Research Associate The Mind Institute

Editing Segmentation Results in TkMedit
by Jared Conley 16 May '07

16 May '07

I am new to FreeSurfer and am attempting to segment T1 images using the "recon-all...autorecon2" command. The segmentation results look quite accurate, but I was wondering how to best edit the results (where there is a need). I noticed on the Wiki a possible option using the TkMedit program. I have tried running the command "tkmedit subjid wm.mgz -aux T1.mgz" as directed, but it gives me an error. Could someone direct me to the correct tutorial or answer my question directly. Thanks. Jared

Can I open images parcellated with an old version of freesurfer (the one parcellating 80 regions) with the new one (based upon the Desikan atals)?

hi, I don't know the procedure of the FreeSurfer? Although the recon-all illustration contains lots of the steps, I don't know the meaning. So I want to know the brief step about the FreeSurfer how to deal with 3D data? Thank you very much hankee，duhanjian(a)sohu.com 2007-05-05

Dear Users: I would like to ask how to treat the data of a subject for whom segmentation worked alright but the parcellation looks like the one I am herein attaching.

intergroupavg-sess did not create a sig.bhdr file
by Avram Holmes 15 May '07

15 May '07

To anyone not outside enjoying the nice weather, I have recently completed running intergroupavg-sess intergroupavg-sess -analysis taumax30_stc_smooth6 -contrast Rcue_v_Ncue -group1 LowTrauma -group2 HighTrauma -intergroup LowTrauma_v_HighTrauma -space tal Only 'minsig' and 'sig' files were generated. However, no sig.bhdr files were created. I just wanted to check to see if everything is as it should be. Also, when I run tkmedit-sess in an attempt to view the data on both the between and within group (where all the normal files were created) analyses... tkmedit-sess -analysis taumax30_stc_smooth6 -s LowTrauma_v_HighTrauma -isxavg random -contrast Rcue_v_Ncue -space tal -d . I recieve the following error... -------------------------------------------------------------- tkmedit-sess logfile is /Raid/shared/exp/REfMRI/fMRI_FPPREW/functional/log/tkmedit-sess.log -------------------------------------------------------------- setenv SUBJECTS_DIR /exp/REfMRI/fMRI_FPPREW/structural/ INFO: Found session in: ./LowTrauma_v_HighTrauma INFO: LowTrauma_v_HighTrauma is a group average INFO: Found session in: ./LowTrauma_v_HighTrauma INFO: LowTrauma_v_HighTrauma is a group average INFO: subject is talairach INFO: subject is talairach ERROR: subject talairach does not exist in data base SUBJECTS_DIR: /exp/REfMRI/fMRI_FPPREW/structural/ Do I have to take any steps to add the talairach brain to my studies 'structural' folder so that I can use tkmedit-sess or is this error related to something else.
