well, we don't run only those steps to generate any volume. Probably your best bet would be the norm.mgz, although as Doug says it will have a cerebellum in it, which you can strip with the aseg.mgz cheers Bruce On Sun, 23 Jun 2019, ping cao wrote: External Email - Use Caution

It does 1-3. It also labels cerebellum which you could then use to perform #4 On 6/23/2019 7:03 AM, ping cao wrote: External Email - Use Caution Dear expert, Thank you for reading! I want to do these four pre-processing steps: 1. Re-sampling each MR image to 256*256*256; 2. Using the

If 4.5 will actually run on 5.0 preprocessed data, then I think it should be ok, but it has been a very long time since 4.5 so I can't say with any confidence. doug On 04/08/2015 01:33 PM, Katie Bettencourt wrote: I had a question about using different components of Freesurfer 4.5 and

[Freesurfer] question about preprocessing and analysis in FS 4.5 vs FS5

2015-04-08 Thread Katie Bettencourt
I had a question about using different components of Freesurfer 4.5 and Freesurfer 5 in an analysis. We were wondering whether it is possible to do preprocessing in Freesufer 5, but run the analysis on Freesufer 4.5 or whether the output from preprocessing in Freesurfer 5 is not compatible with

[Freesurfer] Question after preprocessing in FreeSurfer.

2011-12-27 Thread Long
Dear all, Hi, I am a beginner of FreeSurfer. Recently I have run recon-all and preproc-sess on my MRI and fMRI images. Next I'd like to convert surface images to AFNI-SUMA and convert fMRI images to volume space. I found that the T1 image and its surface maps were not normalized and the fMRI
