The spectral maps contain the LCModel input spectra, fits and baseline fits as a time course (the x-axis is in fact chemical shift in ppm). Additional info is provided by the maps "0_pha_map.nii.gz", "1_pha_map.nii.gz", "SNR_map.nii.gz", "FWHM_map.nii.gz", "shift_map.nii.gz", "SNR_PseudoReplica_spectral_map.nii", "SNR_PseudoReplica_time_map.nii.gz", "FWHM_NAA_map.nii.gz", which are the zero- and first-order phase, SNR, FWHM, and spectral shifts as fitted by LCModel. The last three of these maps are the SNR in spectral and time domain, and the FWHM of NAA calculated by our own scripts. Zip files were updated on 2024-12-13 as files LCMFit and LCMInput were modified to include the baseline.Magnetic resonance spectroscopy data measured from a brain of a healthy volunteer at 10. 5 tesla. These data show the metabolic maps, CRLB maps and LCModel fits, input data and fitted baseline in nifti-format. The volunteer was measured three different resolutions (4.40 mm³ isotropic, 3.44 mm³ isotropic, and 2.75 mm³ isotropic) using a concentric ring trajectory (CRT) FID-based sequence, reconstructed using a discrete Fourier transform, and fitted with LCModel (for more details, see below). The metabolic maps are in auxilliary units (a.u.) and are not in physical units. All these files can be viewed with freeview of freesurfer 7.1.1. It is being released to allow researchers to fully appreciate these 3D datasets, which are hard to otherwise visualize.Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/magnetic resonance spectroscopy10.5 Tmetabolic mapsDatasethttps://doi.org/10.13020/pp73-qj83
