[Freesurfer] aseg, aparc regions reference table (aka "data dictionary")?

Folks: It would be *really* great if there was a page somewhere (or just a file) giving some info on the various measures that are captured in the aseg and aparc files. For each measure (in the table or the "comments" above the table): -- Description of what it includes -- some are obvious f

Hi Graham, the ICV (or eTIV) we use is from a clever idea that Denise Head and Randy Buckner had. They showed that the total intracranial volume could be accurately estimated from the jacobian of the talairach transform (to an atlas with a skull), so the eTIV is just linearly related to the de

Hi Neel, the .annot files should have the color table embedded in them precisely to avoid this type of confusion. I think Doug has a tool for extracting the color table from the .annot file, don't you Doug? cheers, Bruce On Mon, 24 Jul 2006, Neel Kishan wrote: surface_labels.txt has 94 ROI

surface_labels.txt has 94 ROIs in contrast to the 81 in Simple_surface_labels2005.txt, and it does not seem to match the numbering system I find in SUMA. Does this file indicate that there is another parcellating method to identify 94 ROIs? Nick Schmansky wrote: Simple_surface_labels2005.txt

Thanks for the information. Please note that Simple_surface_labels2005.txt was not distributed in v3.0.3 for Mac OS X Tiger. To convert an annot file to roi file for SUMA the following lines can be used for each hemisphere: FSread_annot -input $SUBJECTS_DIR/subject/label/rh.aparc.a2005s.ann

I've just modified the way the DEV version of mri_convert reads in generic (ie, non-siemens) dicom files. This change makes it so that it can convert multi-frame GE (and possibly other) dicom files. Thanks to Adam Thomas at NIH for supplying the GE data. I've also fixed a slight bug in the w

Hi Neel, there's not really an internal order to the annotations (they are coded by the RGB value). I would suggest posting to the afni list. Alternatively, you can use tksurfer in combo with suma to reverse engineer what they've done. doug Jenni Pacheco wrote: Hi Neel, You could refer

Hi Neel, You could refer to the surface label files that should be in your $FREESURFER_HOME directory. I believe that the $FREESURFER_HOME/Simple_surface_labels2005.txt corresponds with aparc.a2005s.annot parcellations and the $FREESURFER_HOME/average/colortable_desikan_killiany.txt correspo
