I have the data from a blocked fMRI experiment of one male subject performing a finger tapping task. This was approved by the IRB at National Children's Hospital in Columbus, OH.
The parameters of scanning are:
2400 files
Task is right-hand finger tapping
every 20 files is one volume
total 120 volumes
each volume acquired in 3 seconds
total scanning time is 6 minutes
spatial resolution is 2x2x8 mm
dimensions 128x128x20
I want to do a preprocessing of the fMRI data using SPM12 to extract the BOLD time series. First, I am confusing about the structure and the number of the files, in normal using SPM12 the files are the volumes, but here I thought it the slices how can I make the 120 volumes from these 2400 files. Second, when I check the format of the 2400 files I got the result (Type de fishier: Fichier "windows language French") and they did not show up when I want to select them using SPM12 GUI, knowing that usually, the formats that we find are: .img, .hdr, .nii, .dcm.
