Cannot open NIfTI file: headerSize is not 348 or 540.

I am testing 4 D nii images. But Cannot open NIfTI file: headerSize is not 348 or 540, and Error using ReadFcn @(x)(niftiread(x)>0) function handle for file.

[Rishita]

V = niftiread( filename )

Reads the NIfTI image file specified by filename in the current folder or on the path, and returns volumetric data in V .

The niftiread function supports both the NIfTI1 and NIfTI2 file formats.

V = niftiread( headerfile , imgfile ) 

reads a NIfTI header file .
