Hello, I am trying to import a 4 dimensional data FITS file: 1024 x 1024 x 272 x 1. This file is a bona fide FITS file, created by the Canadian Astronomy Data Centre (more precisely it is one file extracted from the Canadian Galactic Plane Survey: http://www1.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/cgps/query.html). After the command, nebula=Import["CGPS_MB2_HI_line_image.fits.gz",{"GZIP","FITS"}]; here is the error message I obtain: Import::errstruct: "Malformed data structure. \!\(\"Missing required \ keyword BITPIX\"\)." Using another software, I have checked that the required keyword exists... My question: is Mathematica able to handle FITS files having more than 2 dimensions (data cubes, etc.)? Thanks in advance for your reply. Yves Grosdidier
