Do I need to strip off all the additional planes of zeros before matching the fMRI data and the atlas?

Dear all,

I hope this email finds you well..

I have a question about what kind of processing should be done before matching the fMRI data and the atlas. I got a suggestion that “additional planes of zeros should be firstly stripped off before changing the atlas to match the data”. If the Harvard-oxford atlas and the preprocessed functional image have different number of additional planes of zeros. What kind of processing should be done before matching them.

使用REST1.8运行ROIwise静息态功能连接,生成的zFC文件中没有相关系数,如图

使用REST1.8设置好两个球形ROI之后(FC中的ROIwise选项),添加预处理过的静息态数据,勾选detrend和filter,生成的zFCMap(txt文件)没有生成相关被试两个ROI之间的相关系数,如截图。而且ROI_FCMap(txt文件)也没有按照时间序列生成两列ROI信号值。在运行过程中都没有报错。
