Issue with CTF estimation, RELION tries to convert particles even though they are in the right format

This is a template for reporting bugs. Please fill in as much information as you can.

Hello, I recently started processing some data. However, everytime I try to run CTF estimation, I get an error where Relion thinks that the frames are from a previous version of Relion. It then tries to convert them and then errors out and says "Star file is already at version 3.0001.

Please write a clear description of what the problem is.
Data processing questions should be posted to the CCPEM mailing list, not here.
DO NOT cross post a same question to multiple issues and/or many mailing lists (CCPEM, 3DEM, etc).

• OS: [dont know]
• MPI runtime: [e.g. OpenMPI 2.0.1]

You should make sure metadata in the optics group table after conversion is correct.

Please respect our reporting template.

OS: [dont know]
MPI runtime: [e.g. OpenMPI 2.0.1]
RELION version [RELION-3.1]
Memory: [1000 TB]
GPU: [dont know]

This is not useful at all. We need details to investigate.
Also note that RELION 3.1 is no longer supported.

I guess you specified a wrong STAR file to the CtfFind job.
Did you really specify corrected_micrographs.star from the MotionCorr job?
