Particle re-extract cryosparc to relion

open

#1

Hi all,
After “select 2D” in cryosparc, I use “csparc2star.py particles_selected.cs particles.star” to get the star file.Here is the particles.star file with the correct columns

data_images
loop_
_rlnAmplitudeContrast #1 
_rlnCoordinateX #2 
_rlnCoordinateY #3 
_rlnDefocusAngle #4 
_rlnDefocusU #5 
_rlnDefocusV #6 
_rlnMagnification #7 
_rlnMicrographName #8 
_rlnPhaseShift #9 
_rlnSphericalAberration #10 
_rlnVoltage #11

Then I import the star file into relion and re-extract the particle. I got the error:

ERROR: 
Preprocessing::initialise ERROR: input _data.star should contain rlnMagnification and rlnDetectorPixelSize.

Does anyone know how to solve this problem?

Thanks,
