The problem of cryosparc to relion

Hi, everyone. I generate a star file by using Pyem. But I can’t use it run 3d classification successfully in relion. Why? The error is shown below.

The process: cryosparc_P10_J191_009_particles.cs
J191 is local refinement, its particle input from J175 - particle subtraction.

In relion(3d classification):
Input images STAR file:
Reference map: J191_003_volume_map.mrc

have you linked the J175 dir to your relion dir? otherwise it won’t work

@olibclarke Thank you.

So I should do like this, right? But the directory should be make in what?
I generated .star file on local, then uploaded our cluster and linked the 175 dir to relion-project. ​I am not sure what I did is not correct. In another words, the relion-project should be which one. I just created a folder in the same directory as the Relion. See the picture below:

Look at the star file in a text editor. The relative paths that it is looking for have to exist, otherwise you will get errors like you encountered. Make soft links so the files are where the star file expects them to be

Only this information in the Star file. Should I make soft links with J120?

No, you need to soft link the J175 dir to your relion dir

OK. I understand. Thank you very much.
