Re: [Freesurfer] Make_average_subject error
by Furlong, Carolyn 14 May '07

Thanks Doug, I have tried your suggestion and set the command make_average_subject running again. I has been going for several hours but there is no visible change/activity on the console, is this unusual?. Also, there are only 13 subjects, how long would you expect this process to take per subject?

labels for split parcellation
by Catherine Hartley 13 May '07

13 May '07

Hi, I've used mris_divide_parcellation to generate split the automatic parcellation into subregions. When I view the resulting annotation in tksurfer, the label names do not correspond to the subdivision names, so I am unable to tell which division is which (ie, which is rostralanteriorcingulate_div4, as none of them have this name). Is there a way to display these new label names? Thanks, Cate

Difficulties with segmentation follow-up
by Jeffrey Spielberg 11 May '07

11 May '07

Hi, I sent a message to the forum last June regarding a problem with segmentation of the acc we were running into. We kept having areas of the rostral and caudal acc labeled as corpus callosum or "unlabelled subcortical". I got a reply that this was being worked on and I was wondering if this is now fixed in 3.0.4, and if not if there is any timeline for releasing a fix? Thanks, Jeff

Editing Segmentation Results
by Jared Conley 11 May '07

11 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 I think either 3D Slicer or the tkmedit program. (I would prefer to use 3D Slicer if possible since this is the program with which I am more familiar). Could someone direct me to the correct tutorial or answer my question directly. Thanks. Jared

bus error when loading annotation
by Catherine Hartley 11 May '07

11 May '07

Hi, When I attempt to load a custom annotation file (that I created using mris_divide_parcellation) within tksurfer, I get a bus error which seems to result from a problem with the colortable: % reading colortable from annotation file... CTABreadFrom: could not allocate -2 bin table Cannot allocate memory Bus error I'm working on an Intel Mac. Thanks, Cate

mris_anatomical_stats

Hi, I'm trying to get the anatomical statistics for a new parcellation, ? h.aparc.splitcingulate.annot, I've created using mris_divide_parcellation. I've tried using mris_anatomical_stats with various argument structures (specifying output filenames, not specifiying output filenames) and can't seem to get it to write a ? h.aparc.splitcingulate.stats file. It generates and outputs summary statistics, but it does not write a .stats file to the stats directory: [catemac:freesurfer/subjects/reruns] cate% mris_anatomical_stats mm103184 lh inflated -a mm103184/label/lh.aparc.splitcingulate.annot reading volume /Applications/freesurfer/subjects/reruns/mm103184/mri/ wm.mgz... reading input surface /Applications/freesurfer/subjects/reruns/ mm103184/surf/lh.inflated... reading input surface /Applications/freesurfer/subjects/reruns/ mm103184/surf/lh.pial... reading input surface /Applications/freesurfer/subjects/reruns/ mm103184/surf/lh.white... done. computing second fundamental form... ... done. total white matter volume = 516178 mm^3 total surface area = 81462 mm^2 total gray matter volume = 230187 mm^3 average cortical thickness = 2.175 mm +- 0.836 mm average integrated rectified mean curvature = 0.025 average integrated rectified Gaussian curvature = 0.096 folding index = 9766.477 intrinsic curvature index = 937.896 [catemac:freesurfer/subjects/reruns] cate% Thanks for your help! -Cate

mris_divide_parcellation
by Catherine Hartley 10 May '07

10 May '07

Hi, I'm hoping to get a hold of the function mris_divide_parcellation which automatically subdivides the cortical parcellations for a region into sub-regions. It's not a part of the current Freesurfer release but would it be possible to get a copy of the development version? Thanks, Cate
