External Email - Use Caution
Hello FreeSurfer Developers,
I have functional contrast maps from the HCP dataset. I converted these to fsaverage space and now have GIFTIs for the surface data and a NIFTI for the subcortical volume data. I would like to combine these into one file for an analysis where I will be predicting the intensity of individual voxels. I thought I would use vlrmerge to do this, but noticed that the documentation notes that vlrmerge should only be used for visualization purposes. I was wondering if you thought that doing my analysis on the vlrmerge output would be a bad idea, even though I am not doing any real computation on the merged volume maps.
If this is a bad idea, is there another method that I can use to combine the surface and subcortical volume data?
Thank you.
