MM human brain spectra 9.4T - TE series / Fit Settings LCModel

This are TE series (TE = 24,32,40,52,60 ms) DIR semi-LASER macromolecular spectra. They were measured in the occipital lobe (in GM rich and WM voxels) of the human brain. The provided data are averages from 11 subjects. Additionally, the fitsettings and sample fits are provided. An explanation on how to set up the fit settings file is provided in the Readme.MD.

MM Consensus Data Collection

This repository contains a number of pre-processed macromolecule (metabolite-nulled) spectra in Varian format (sometimes converted from Siemens format), acquired at different field strengths from different mammals, including human. These data are represented in Figure 1 of the recently published consensus on macromolecule acquisition and handling.
