Intensity plot box for NIFTI images *with* time dimension is all white

[gdevenyi]

Loading a NIFTI timeseries image results in a solid white box where the intensity plot usually is.

Converting the NIFTI to MINC and loading it displays properly.

@gdevenyi Thanks - I don't see this with the few functional files I have, can you give me any details about the file (e.g. the output of nifti_tool -infiles -disp_hdr)?

Thanks, I think this is a units issue, as this file is using msec instead of seconds for the time units - I'll test that theory soon.
