Hi. I'm a medical student and I'm trying to use the QuickNATv2 MATLAB code for structural MRI segmentation for a paper. However, at the last step when I want to execute the Run command for this program, it returns an error related to MRIRead function from freesurfer. I'm, using windows so I Cloned freesurfer library from github and defined its path for MATLAB. The error is:

SWITCH expression must be a scalar or a character vector; the MRI data is a .mgz file:

Error in load_mgh (line 166)
switch type

Error in MRIread (line 94)
[mri.vol, M, mr_parms, volsz] = load_mgh(fspec,[],[],headeronly);

Error in RunFile (line 15)
DataVol = MRIread([DataPath,FileName]);

I've also tried using linux shell for windows 10 and installed the freesurfer with it but i still get the same error. I didn't find any helpful guides on various forums so I'm mailing you hoping to find a solution cause I really need to run the QuickNAT for a paper.
