4D Nifti files for seed-based correlations

Experiment information: Transcranial alternating current stimulation was delivered during 3T fMRI using concentric circular electrodes over area P4 in stimulation periods that each included attention task and resting-state blocks. MR images were preprocessed, normalized and denoised using the CONN toolbox for Matlab (https://web.conn-toolbox.org/) and analysed using seed-based correlations.File information: This repository contains gzipped 4D-Nifti files of seed-based correlations as calculated using the Matlab CONN toolbox. Each filename refers to SBC__Subj.nii.gz. Each4D Nifti file contains 11 volumes that refer to the 11 experiment conditions:Volume 1 = null; Volume 2 = rest 10 Hz; Volume 3 = task 10 Hz; Volume 4 = rest 20 Hz; Volume 5 = task 20 Hz; Volume 6 = rest 40 Hz; Volume 7 = task 40 Hz; Volume 8 = rest 5 Hz; Volume 9 = task 5 Hz; Volume 10 = rest No Stimulation; Volume 11 = task No Stimulation.Seed correlation values are Fisher Z-normalized (for more information, see the CONN toolbox or the associated manuscript).

实验信息：经颅交流电刺激（Transcranial alternating current stimulation）在3特斯拉功能磁共振成像（3T fMRI）期间施加，采用同心圆电极置于P4脑区；每个刺激周期包含注意力任务和静息态模块。磁共振图像通过Matlab的CONN工具箱（https://web.conn-toolbox.org/）进行预处理、标准化和去噪，并采用基于种子点的相关性（seed-based correlations）分析。文件信息：本仓库包含使用Matlab CONN工具箱计算得到的基于种子点的相关性的压缩4D-Nifti文件。每个文件名格式为SBC__Subj.nii.gz。每个4D Nifti文件包含11个容积，对应11种实验条件：容积1 = 空白；容积2 = 10Hz静息态；容积3 = 10Hz任务态；容积4 = 20Hz静息态；容积5 = 20Hz任务态；容积6 = 40Hz静息态；容积7 = 40Hz任务态；容积8 = 5Hz静息态；容积9 = 5Hz任务态；容积10 = 无刺激静息态；容积11 = 无刺激任务态。种子点相关值经过Fisher Z标准化（Fisher Z-normalized）（更多信息请参见CONN工具箱或相关手稿）。
