Sophie,
First, I want to clarify what you did. I think you mean this:
* you generated a "*segment_vent_corr*mnc file using SureFit
* you imported this .mnc as a segmentation volume into Caret
* you used Volume:Segmentation: Edit Voxels to patch the .mnc
* you tried and failed to flatten the hemisphere
Assuming the above scenario reflects what you did, then I suspect you
didn't successfully run Prepare for Flattening in SureFit with the
patched volume loaded. John Harwell alluded to this in his previous
reply. Try this:
* after you patch in caret, do Save Data File: Volume Files - SPM and
Medx (.hdr). Select volume type: Segmentation and Volume File: whatever
label caret imported your segmentation as (e.g., volume0).
* run Analyze2Minc on the resulting "myseg.hdr" file
* load your cropped structural volume and vol1 in SureFit, myseg.mnc as vol2
* Run SureFit with these settings:
use segmentation in vol2
fill ventricles no
correct errors no
prepare for flattening
identify sulci yes
I think this will work. If you failed to run the final, patched
segmentation through SureFit's prepare for flattening, then caret would
be unable to find the ellipsoid and other files needed to flatten the
surface.

Hi,
I have just constructed surfaces in Caret 5 on a pc, using a
segmentation imported from SureFit.
I have corrected the handles but when I try and flatten the
elipsoidal hemisphere I get a fatal error and the program crashes
out. I think I am following the instructions correctly. Do you
know what the problem could be?
