Hi Jared
It isn't a problem with splash is it? Did you compile splash using big endian so that's what it's expecting, and your maching is writing a little endian file?
Other than that, I would copy gadgets io routine to see if you can read in the file yourself, without splash. If that still doesn't work, then maybe someone more experienced can help on this list!
Best wishes,
Cass

Subject: [gadget-list] Snapshot files
I’m trying to run the standard galaxy test on 16 cores. When I get data the snapshot files are 1.7 mb and the restart files are 11 mb. When I try to use gsplash to visualize the results it tells me that no particle data has been found. What am I doing wrong?
Here is my parameter file
