Predifined ROI using

Submitted by syang on Mon, 06/27/2016 - 15:28

Hi, I'm Seungnam.

I want to use each patient's  RO I file that is predefined using each subject T1 image.

How can I do?  use the ROI file using  Mask file at Define ROI-> Define Other ROI-> Mask+

                                or

                               use the ROI file  after making the Text file  using Define ROI-> Define Other ROI-> Seeds+

What is the difference of these two methods?

If I want to analyze the patient's original space not MNI space, is it possible and how can I do?

Hi,

If you already have a mask file for the ROI, use Mask+.

If you already extracted the time course for that ROI, use Seed Series+.

In you case, the best way is: http://rfmri.org/comment/4311#comment-4311

Thank you!

I relieved my question. 

I should use Mask+.

I have 30 subjects and 4 ROI of each 30 subjects. Each subject's have each 4 ROI of each subject's original space.

Can I analyze the 30 subjects simultaneously? If it is possible, how can I define the ROI using Mask+?

Hi Seungnam,

You can do one ROI for 30 subjects at a time.

Please read http://rfmri.org/comment/4311#comment-4311 carefully.

Thank you for your answer. 

In your previous comment, you explained about seed time course series just like below.

Choose a configuration file, e.g., Config.txt

The contents should be:

Seed_Time_Course_List:

/XX/MaskSub1.nii

/XX/MaskSub2.nii

/XX/MaskSub3.nii

 

How can I make the text file when I use ROI using the mask+ ?
 
Is it right like this?
                 Mask_List:
                /XX/MaskSub1.nii
                /XX/MaskSub2.nii
                /XX/MaskSub3.nii
 
When I have 4 ROI of each subjects, should I make 4 text file?

Keep "Seed_Time_Course_List:".

Yes, 4 text files.
