Dear all,

I have exactly the same thing with v 1.3. relion_project crashed at the end with Seg. fault, however the new stack file was created and used further in 3D refinement.

Best,

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):
Done reading STAR file!
000/??? sec ~~(,_,">                                                          [oo]Segmentation fault (core dumped)

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:
Done reading STAR file!
   3/   3 sec ............................................................~~(,_,">
 Done writing 266 images in temp.star
Segmentation fault (core dumped)


I am running relion 1.4 compiled with gcc 4.8.4. 
Any idea of where the bug could come from?


Best wishes
Ben
