does it let you load the fsgd without a register.dat? If not, you can create one with
tkregister2 --noedit --mov sig.mgh --targ FMRIB58_FA_1mm.nii.gz --regheader --reg register.dat

The 4D input file of FA values was created using the TBSS processing stream where each subject was registered to the FMRIB58_FA_1mm.nii.gz standard brain in the FSL directory. However, the volume I used as the input for the glmfit is basically a 4D volume of alrealdy registered subjects that has been masked to only leave a skeleton of white matter tracts. The order of the FSGD file corresponds to the order of each subject's registered FA skeleton map in the 4D volume.

Is is already registered to a subject?

Hello, I ran a GLM using a 4d skeletonized Fractional Anisotropy volume as my input into mri_glmfit with one variable. As this analysis is not surface based, I must open the results (sig.mgh) using tkmedit as an overlay. My goal is to open a scatterplot similar to that in tksurfer which shows the voxel value vs. variable score for each individual subject at a particular location. When I try to load the GDF file (the y.fsgd output in glmdir right?), it also asks for a registration file. I don't think there is a register.dat file as an output in the glmdir.... so, I was wondering what registration file it is looking for?
