# IndividualBrainConnectivity
The codes shared in this folder can be used to replicate the results explained in “Menon, S. S. & Krishnamurthy, K. A comparison of static and dynamic functional connectivities for identifying subjects and biological sex using intrinsic individual brain connectivity. Sci. Reports 9:5729, https://doi.org/10.1038/s41598-019-42090-4 (2019)”.
Initially preprocessed data has to be downloaded from the HCP website. For 3T, resting state file named “rfMRI_REST_1/2_LR/RL_hp2000_clean.nii.gz” has to be downloaded for sessions 1_LR, 1_RL, 2_LR and 2_RL and task file named
“tfMRI_task_LR/RL.nii.gz” for tasks EMOTION, GAMBLING, LANGUAGE, MOTOR, RELATIONAL, SOCIAL and WM LR and RL configurations. For 7T, resting state file named “rfMRI_REST1/2_7T_PA/AP_hp2000_clean.nii.gz” has to be downloaded for
sessions 1 PA, 1 AP, 2 PA and 2 AP.
The next step is to download the Stanford functional atlas which can be downloaded from the link https://findlab.stanford.edu/functional_ROIs.html. To extract time series for the parcelled ROIs, we can use the following FSl command:
fslmeants -i <input_path> -m <mask_path> -o <output_path>
Input_path can be pointed to the downloaded fMRI data, mask_path to the ROI mask downloaded and output_path to the location where the time series text file has to be saved.
Finally, you have to save the time series as a MATLAB file of size 90 x time points (use MATLAB, for our program 343RfmriTimeseries consists of 1372 variables named subject_session.mat (90*1200) and a subject variable with 1372 cells to identify session and subject, similarly for other resting state and task data). Now we can use the MATLAB files provided here to replicate the results. The main program can be called to output the results presented.

matlab分时代码个人脑连接 在此文件夹中共享的代码可用于复制“ Menon,SS&Krishnamurthy,K.”中所述的结果。静态和动态功能连接性的比较,用于使用内在的个体大脑连接性来识别对象和生物性别。 科学Reports 9:5729,(2019)”。 最初的预处理数据必须从HCP网站下载。 对于3T,必须为会话1_LR,1_RL,2_LR和2_RL下载名为“ rfMRI_REST_1 / 2_LR / RL_hp2000_clean.nii.gz”的静止状态文件,并为任务EMOTION,GAMBLING,语言,电机,关系,社交和WM LR和RL配置。 对于7T,必须为会话1 PA,1 AP,2 PA和2 AP下载名为“ rfMRI_REST1 / 2_7T_PA / AP_hp2000_clean.nii.gz”的静止状态文件。 下一步是下载可从链接下载的斯坦福功能图集。 要提取包裹ROI的时间序列,我们可以使用以下FSl命令: fslmeants -i <输入路径> -m <掩码路径> -o <输出路径> 可以将Input_path指向下载的fMRI数据,将mask_p
