Hi everyone,
I had a 4D NIfTI file, but only needed a few of the volumes.
To access those, I first used spm_select('expand', 4Dfile) and then saved the ones I wanted in a new variable.
However, now I want to merge them again into a new 4D NIfTI file with only the subset of the volumes.
I tried spm_file_merge, but this creates a struct instead of the 4D file I want.
Does anyone know how to merge the subset of 3D files into a 4D NIfTI file and save it?
Thank you,
Lotte
