Hello, does anyone know how to convert a 4d (3d+time) BOLD image into a 3d (2d+time) flat map of BOLD activity? i have surfaces obtained through freesurfer, and i’m experimenting with SUMA in AFNI, but it seems to be mainly for visualizing single 3d maps (correlation maps, for example) as surfaces.
is there a way to get my raw BOLD 4d image into a 2d+Time flat map (Basically, a time series of flat maps)?
why do i want 2d+t flat maps? because i’m trying to experiment with some CNN for image decoding using FMRI…most approaches i’ve seen have simply stacked the voxels (ignoring spatial relationships between the voxels, and hence not able to use convolutional layers).
