Sadly I am “well-seasoned” enough to remember the vax-Linux byte swaps. Little endian vs big endian, and the whole thing. I was not expecting the Convex reference here which brings back great memories of the Johns Hopkins Convex and the frigid room it resided in that sounded like you put your head in a jet turbine exhaust. Good times.

Not sure what happened to the 11/750, though... School of Pharmacy rings a bell?? None of this matters, but I just thought you might like to practice some 'big-iron' byte-swapping again, and if so, York is the place to go, after covid-19, of course ;-0 ;-0 On Friday, 15 May 2020, 10:47:40 BST, Ian Tickle <ianj...@gmail.com<mailto:ianj...@gmail.com>> wrote: Hi, that would have to be a very old map! I remember implementing the auto-byte swap for VMS (necessary as we had both a Convex C220 running Unix and a VAX 11/750)! In fact the Convex was rescued from scrap by Jim Austin and is still working: http://www.corestore.org/convex.htm Cheers -- Ian Cheers -- Ian On Fri, 15 May 2020 at 09:24, Philippe BENAS <00000d88e888355a-dmarc-requ...@jiscmail.ac.uk<mailto:00000d88e888355a-dmarc-requ...@jiscmail.ac.uk>> wrote: Dear Bernhard, Is it an old map ? Back to the old VAX times I had to dump CCP4 maps to ascii map files, then swap bytes from VAX-DOS to Unix before converting them again to a CCP4 map format (I think I was using mapman from USF) on a Unix workstation and be able to read them in Frodo-Strasbourg or O. At least you could give it a shot and the ascii map file would help you figuring out the issue by a visual inspection of the header and sections.
