Dear experts,
I would like to create a mask including two 3-mm spheres representing right and left dACC, since I am not interested in lateralization of this regions and try to avoid the issue of multiple correction (2, right and left). However, I failed to find the way to create such a bilateral ROI mask. I will be really apreciated if anyone of you could help me to solve this question.
Best,
Vincent

Hi Vincent,
Hi Vincent,
You can use this command
[SphereData, Header] = y_Sphere(Center, Radius, RefFile, OutFile, Unit)
To generate the two Sphere ROIs.
And then you can use Image Calculator: i1+i2 to add them together.

Hi Chao-Gan,
Hi Chao-Gan,
Thank you for your rapid reply.
Because I am not familiar with the use of command, I still have some questions. I wonder if the following steps are correct: 1. type this command in the command window in Matlab, 2. replace (Center, Radius, RefFile, OutFile, Unit) with specific items.
In addition, I would like to confirm with you the meaning of the command. [SphereData, Header] is the function used in rest? Center and Radius are with obvious meaning, but what the RefFile, OutFile, and Unit (millimeter?) stand for?
Thank you in advance,
Vincent
Hi Vincent,
Hi Vincent,
RefFile: a file define the space that you want to create the ROI.
OutFile: A filename you want to output the ROI.
Unit: just leave it blank, it will use XYZ millimeter coordinates.
You can ignore the output data "SphereData, Header", but just look at the output file "OutFile".
Best,
Chao-Gan
