Too many .nii.gz files

Hello, when I use FunImg as my starting directory, I get this error

"Too many .nii.gz files in each subject's directory, should only keep one 4D nii.gz file"

Both FunImg and T1Img were created in a previous run, so I don't understand why this error ?

appreciate any suggestions,

thank you.

It is supposed that each subject's FunImg directory contains only one 4D file. You may check which subject has more than one file, then go back to see whether his/her FunRaw directory contains other subject's DICOM file.
