MATLAB code to read 4D rsfMRI

Hi

I am just trying to write my own MATLAB code to do some part of preprocessing. I need to conver the list of 4D rsfMRI data to 3D. In fact I have 5 subject data in the list and each one has 450 timepoints rsfMRI. I want MATLAB read each 450 timepoints and average them together and give a 3D data for each subject.

Can you please help me to prepare this part? I really appreciate that.

Regards

Start doing preprocessing of rs-fMRI

Submitted by FaezeVedaei on

Hi 

I am beginner in using DPARSF. Just wanted to start doing preprocessing of resting-state data through advanced DPARSF, but saw that the session for uploading each subject's data does not working. I just gave the directory path but could not upload data. Can you please clarify me how I can do this step? 

 

Also, beside that I wanted to access to default mask provided by DPABI for ICC measurement on rs-fMRI. Can you please tell me if this is already available on the tool, is so how I can find that?

Thank you so much in advance for help.

用dpabi处理被试灰质时,进行到roi signal出现了报错(2)

尊敬的严教授:

        您好!因为之前的帖子没法把图片贴到正文,所以我又开了个窗口,望理解。之前的帖子链接是:http://rfmri.org/content/%E7%94%A8dpabi%E5%A4%84%E7%90%86%E8%A2%AB%E8%AF%95%E7%81%B0%E8%B4%A8%E6%97%B6%EF%BC%8C%E8%BF%9B%E8%A1%8C%E5%88%B0roi-signal%E5%87%BA%E7%8E%B0%E4%BA%86%E6%8A%A5%E9%94%99

        您说是并行工具箱的问题,我重新下载了matlab又试了试。我做了两种尝试,但是都没有成功。老师,接下来咋办啊?

生成文件显示问题

         尊敬的严老师您好,我在使用dpabi做预处理的时候,发 现中间生成的文件不知道是否存在问题。如图一所示。

         1.为什么在FunImgAR->FunImgARC 这个过程,生成的文件(图一)显示像马赛克一样。这样是正常的吗? 如果是正常的话,我不想要这样的显示,想要所有预处理后的显示结果如图二那样,我应该取消哪步操作?

         2.dpabi 不能对功能像数据进行去头颅操作吗?

 

          对于第一个问题,我下来仔细又看了一次视频,AR->ARC 这个过程是做了去除噪声,但是这样就使得图像看上去像马赛克一样,如果我不做这一步可以吗?会不会有很大的影响?

          希望老师能够解答,感谢!

严老师,您好,dpabisurf的时候报错,不能跑,谢谢您
