Converting individual (ACPC) monkey brains to NMT

Converting VMPs from original ACPC space to NMT

E.g. Y:\MRI\Curius\2NMT\vmp

Original vmp: dPul_p.vmp, “nominal” res 2 mm, actual 1 mm

The approach works with multiple maps within vmp

vmp.ExportNifti('dPul_p.nii'); % or NE GUI
ne_change_nii_header_resolution('dPul_p.nii',1);

Converting electrode localization prob. maps VMPs from original ACPC space to NMT

E.g. Y:\MRI\Curius\2NMT\electrode_localization

Original vmp: el_dPul_p.vmp, “nominal” res 1 mm, actual 0.5 mm
