I have to do a ALFF analysis on fMRI images.
I used matlab 7.4. I did the preprocessing using SPM8. my smoothed images have matrix size 79 95 68 and voxel size 2x2x2. I have 195 scan for each subject.
I would like to run my analysis on a single subject. I detrend and filter the images using no mask.
I tried to use rest1.1 and 1.4, but both of them give me the following error:
error using ===> zeros
out of memory
Load mask "".
Build band pass filtered mask. Wait...
Band Pass Filter working. Wait.......................
ReConstructing 3D+time Dataset. Wait...
Exception occured. (MATLAB:nomem)
Error using ==> zeros
Out of memory. Type HELP MEMORY for your options.
