[Freesurfer] Creating a label

2010-07-21 Thread liang wang
Hi, I can create a label file from either ?h.aparc.annot (using mri_annotation2label) or aparc+aseg.mgz (using mri_cor2label). However, I find the two same label are shown different using tksurfer. Specifically, the label created by mri_annotation2label display compact and clear, whereas one obtai

Hi, I am a freesurfer user at Washington University. I am attempting to return aseg+aparc into native space to implement the images into another pipeline. My native space is 256x256x176 1mm^3 voxels. mri_label2vol does not accomplish this to the raw_avg or the 001.mgz in the subjects orig directory

2010-07-21 Thread Douglas N Greve
This is not possible with QDEC, but you can use an FSGD file to do it (or set up your own design matrix). Do a search on our wiki for FSGD to see examples. doug Jeff Sadino wrote: > Hello, > > I would like to be able to do 3-way anova in qdec, freesurfer version > 4.3.1 and measure the cortica

[Freesurfer] mri_glmfit weighted random effects

2010-07-21 Thread Shanqing Cai
Hi, I have a question about the "weighted random effects" option in the "mri_glmfit" command. Are there any specific references (papers or books etc.) for that approach, i.e., using contrast variance images to weigh the contrast images in a second-level analysis. Also, would it be possible for me
