Data:
Select the MRI data set on ADNI
Requirements:
Preprocess the data using standard steps from the CAT12 toolbox
1. Biased-corrected;
2. Segmented into gray matter, white matter, and cerebrospinal fluid (cerebrospinal fluid)
3. Registered to Monurological Institute (MNI) space using sequence linear (affine) transformation
4. Gray matter The image was resliced to 2mm x 2mm x 2mm, resulting in dimensions of 91 x 109 x 91.
Configuration environment:
System environment: win10
software environment:
1. Matlab r2020b. Since matlab has not been installed before, in order to complete the data preprocessing as soon as possible, the trial version of matlab is installed here;
2. SPM12 (https://www.fil .ion.ucl.ac.uk/spm/)
3, CAT12((http://dbm.neuro.uni-jena.de/cat12/)
Installation
step1: Download the spm12 and cat12 compressed packages. After decompression, put the cat12 folder under spm12/toolbox/; step2:
Open matlab, click "Set Path" and add the spm12 path;
step3: Enter spm on the command line, Press Enter to get the following page:
click fMRI,
click Toolbox, and select cat12.
Click Segment and get:
step4: After entering the above page, first click Volumes and select the image to be processed; Split job into separate process can choose to use several threads;
step5: Finally, click the green triangle in the upper left corner to run and wait patiently.
