[Freesurfer] mri_nu_correct.mni intensity correction problem

2009-10-05 Thread Jeff Sadino
Hello, I am running FS 3 and am having problems with auto-recon1, in particular the mri_nu_correct.mni step. My orig volume has intensities around 150-250, but my nu.mgz image has intensities all below 20. I am having errors further down the line, but I think they are all due to this step. C

Hi, Annotation option is not available in the stable release version. If you are able to run the development version, you can load annotation file from the Surface control panel on the left. Or you can load it from the command-line like: freeview -f surface_filename:annot=annotation_filename Bes

Guang, You are correct in noticing that the segstats stage appears to run during -autorecon3. It was moved to run during that stage, but the flags to enable it exist in -autorecon2, so that needs to be updated for the next freesurfer release. Nick On Mon, 2009-10-05 at 17:47 -0500, Guang Zeng

Dana, First I would run: recon-all -s subid -clean to remove any prior control points and edits. Then I would open nu.mgz: tkmedit subjid nu.mgz and *sparingly* put control points well into white matter areas on a few different slices. you only need a half dozen or so. to add control points

Hey Doug - first of all, thanks for the reply. second - 1. I'm afraid i didn't get the explanation. what is the FIR, and what does it mean "two samples in the FIR" ? 2. ok, thanks. isn't it strange though? how do researches jitter the ISI than? manually? 3. thanks.

Hi Nick, Below is Bruce's response to a problem I'm having with the gray/white segmentation. (Pasted below, you can see the brainmask.mgz volume and surfaces--the entire brain is labeled as white matter). I could use some guidance in carrying out his advice. He says to adjust the intensity

Hi Alex, it's hard to tell from just the one slice. Is there a topological defect there? You can look at the orig.nofix/inflated.nofix to see. If not, you could try changing the intensity thresholds in mris_make_surfaces with the export opts (and look in the recon-all to see what they are set to
