Dear Sjors and list

I have a segmentation fault occuring with relion_project 

I use the same options as those given in the latest gamma secretase paper (—subtract_exp etc.)

It is somewhat mysterious: first time I used it it ran until it created the particle star file and then crashed with a segmentation fault. So I could use the star file and the corresponding mrcs particle file to run a reconstruction. 

Now it crashes just after reading the input star file. No mrcs or star file is created. I get this output (just the last lines are copied here):

If I now remove —subtract_exp, the program runs until it has written the mrcs and star files, and then it crashes with this output:

I am running relion 1.4 compiled with gcc 4.8.4. 

Any idea of where the bug could come from?

Best wishes

Ben
