Surface to volume mappings were then used to transform the group MMP parcellation from fsaverage space into native T1 space. Finally, transformations from native T1 space to the desired template space were applied to transform parcellations into the desired spaces. Individual participant's projections were used to estimate probability maps for each study separately. The resultant study specific probability maps were averaged. Data from two different studies (N=89 and N=241), are incorporated. fmriprep 20.2.3 was run with the --recon-all flag to produce all necessary spatial transformations.Refer to methods.txt for scanning protocols and participant details.

本数据集包含经配准融合（registration fusion）处理后投影至体素空间的Glasser等人的组水平MMP皮层分区图谱。该体素空间适配两种不同的标准模板：
MNI152NLin6Asym：即FSL/HCP的“标准”空间
MNI152NLin2009cAsym：即fmriprep的默认空间

glasser_MNI152NLin[2009c|6]Asym_atlas.nii.gz：投影至两种标准模板空间的概率分区图谱
glasser_atlas_labels.txt：上述分区图谱的标签文件，各行标签的顺序与体素顺序一一对应
[lr]h_[bmrk5|paingen]_MNI152NLin[2009c|6]Asym.nii.gz：适配模板空间的个体专属皮层分区文件，每个半球对应一个文件（lr分别代表左右半球）
[rl]h.HCP.MMP1：重采样至fsaverage表面空间的Glasser图谱（rl分别代表左右半球）
methods：研究方法说明文档（虽为非正式表述，但整体仍具严谨性）

本数据集的组水平MMP表面分区图谱首先从fs_LR空间重采样至fsaverage表面空间；随后通过表面-体素映射将该分区图谱从fsaverage空间转换至原生T1空间；最终通过原生T1空间至目标模板空间的空间变换，将分区图谱投影至目标模板空间。针对两项独立研究，本数据集分别基于个体被试的空间投影结果估算分区概率图谱，并将每项研究得到的专属概率图谱进行平均融合。本数据集整合了两项独立研究的数据，样本量分别为89例和241例。本分析采用fmriprep 20.2.3并结合--recon-all参数运行，以生成所有必需的空间变换矩阵。详细的扫描方案与被试信息请参考methods.txt文件。
