Importing relion 3 particle star fails in CryoSPARC 3 (bug)


When I try to import a particle star file from a polishing job executed in relion 3.1, I get the attached error. It seems like CSPARC is trying to confirm the offsets from Angstroms to pixels and failing. If I manually change the column labels in the star file to rlnOriginX/rlnOriginY instead of rlnOriginXAngst/rlnOriginYAngst it imports correctly.

Hi @olibclarke,

Are you running cryoSPARC v3.0.1? This bug was fixed in this version.

Hi @stephan, I was not but am now, so good to know!


Hi @stephan,

I still see the same bug in 3.01 (with a slightly different error message):

Hey @olibclarke,

Can you send me your star file? It doesn’t need to be the entire thing, just one or two rows would be great. Thanks!
EDIT: Can you also send me the entire contents of the “Overview” tab?

Hi @stephan, sure thing - I will try to find the star file and DM you. Thanks!

That’d be really helpful. Thank you!

I have the same problem

Is there a solution?

Read the first post - change rlnOriginX /rlnOriginY to rlnOriginXAngst /rlnOriginYAngst in the star file. If you really need the offsets to be right (for local refinement, for example) you may also need to do some math on the values

Hi @olibclarke, @jiskander,

Sorry for the inconvenience, a fix for this will be released in v3.1.


Thanks I saw that and solved. It will be helpful if we did not need to do that.

@jiskander We have released a v3.1.0 update to cryoSPARC in which this issue should be resolved. Please let us know if this issue persists in v3.1.0.
