Time series analysis and ROI signal folder

Submitted by aminuj on Mon, 07/17/2017 - 16:59

Hi all, 

So after processing and extracting roi signals, the next step is for me to analyze the roi signals of my subjects using SPSS. Does anyone know what type of analyisis I should carry out on SPSS as I have two groups, one healthy and the other  have Alzheimers.
Whic do I use rregression or corellation.

Also what does the different type of file mean in the results folder for roi extraction. does  Z mean zett?

 

much appreciation, really  benefiting from this program!!

So I have been having major issue with this, I want to run a dartel normalisation, smooth, detrend etc... but i keep getting an error message when I reach the coreg part of T1 and Fun. 
If you look at the picture i attached you will see my parameters. I'm sure i have all the files laid out as the programme instructs.

thanks for your help.

严老师：

          你好。我在使用DPARSF做Normalize时，采用的是EPI模板。但仍然报错“No T1 image has been found.”但之前的所有步骤均未选择读取T1像。

          如果我用DPARSFA做，则报错

Do I have to start all over again if the pre-processing is interrupted?

Hello Guys,

I am trying to do the pre-processing of data, but it stopped after generating folder "Reorient mats". It stopped because I clicked on "Define ROI" in the same tab as "QC score tab". it gave the error as follows:

 Moving Head Motion Corrected Files:Sub_002 OK

hi,

    when I use the matlab under Linux system, once I tyoe "dpabi", the matlab will be jamed and the other previously launched procedure, such as REST, also could not   continue to use.  The matlab was like dead and I can do nothing. When 25 mins later, the dpabi gui was shown up. However, when I further clicked the "viewer" or other button, there was an error appearing:"undefined function or variable ‘DPABI_VIEW'".

mask does not matcȟ error (Y Extract ROISignal)

Submitted by aminuj on Fri, 07/07/2017 - 11:24

Hi everone so i'm faced with a mask size error. I require a size of 64x64x48. But the default mask provided by DPARSF appears to 80x80x48. Also when I input 'no mask' I get this error.
1. How do I get a mask that is 64x64x48.
2. If I build a ROI using the program Marsbar how do I use it in DPARSF and do I have to do any processing for it to work on DPARSF.
**look at attached image please.

Any advice is appreciated, thank.
