When loading NIfTI with NiBabel, format is set to NIfTI1 by default (format required : NIfTI2)

In nifti2Collection class, when loading several files from a filename list and printing out headers, I noticed NIfTI1 format was used for loading by NiBabel.

Dr. Rech specified files would be in NIFTI2 format.
