Dear FreeSurfers,
I was wondering if anyone had tried to use the MATLAB LME toolbox that you kindly developed for volume based VBM-style data? Either way would you be able to impart some initial advice as to considerations that should be made etc?
Best wishes and many thanks,
Sean
Hi Sean
If you can load the 3D VBM data into Matlab as a matrix Y(nm x nv, nm total number of VBM maps and nv total number of voxels) then you can use lme_mass_fit_vw to fit a voxel-wise lme model (the region-wise approach is not yet implemented for euclidean 3D data).
You should ask to the list but I think there should be a way to stack all your VBM maps into a single .mgh file. For 2D surface data that can be accomplished with mris_preprocbut I don't know if you can use it with volumetric data. Once you have your datain a single .mgh file you can read it into Matlab using the lme toolbox's fs_read_Yfunction as explained in the wiki and perform your analyses.
