can't import relion-3.1 particles to cisTEM

Relion has recently updated ver3.1 and its star file changes a lot, and then I found it could not import into cisTEM to run. New star file seems like:

data_optics

loop_
_rlnOpticsGroup #1
_rlnOpticsGroupName #2
_rlnAmplitudeContrast #3
_rlnSphericalAberration #4
_rlnVoltage #5
_rlnImagePixelSize #6
_rlnMicrographOriginalPixelSize #7
_rlnImageSize #8
_rlnImageDimensionality #9
           1 opticsGroup0     0.100000     2.700000   300.000000     1.310000     1.310000          256            2

# version 30001

data_particles

loop_

_rlnCoordinateX #1
_rlnCoordinateY #2
_rlnClassNumber #3
_rlnAutopickFigureOfMerit #4
_rlnAnglePsi #5
_rlnImageName #6
_rlnMicrographName #7
_rlnCtfMaxResolution #8
_rlnCtfFigureOfMerit #9
_rlnDefocusU #10
_rlnDefocusV #11
_rlnDefocusAngle #12
_rlnCtfBfactor #13
_rlnCtfScalefactor #14
_rlnPhaseShift #15
_rlnGroupNumber #16
_rlnAngleRot #17
_rlnAngleTilt #18
_rlnNormCorrection #19
_rlnLogLikeliContribution #20
_rlnMaxValueProbDistribution #21
_rlnNrOfSignificantSamples #22

Compared to old formate, the "_data" changes to "data_optics" and "data_particles" or "data_micrographs" and so on. 

However, when I use relion_stack_create then import particle to cisTEM, it cannot work. It reported

Error: Encountered the following error - aborting :-
Error: Couldn't find _rlnDefocusU in star file (/ssd/relion_benchmark/to_cistem.star)

Help?

Hi,

Hi,

cisTEM cannot read the new star file format yet.  Just looking at what you wrote above - If you remove the data_optics section, then rename "data_particles" to _data it may work?

Thanks,

Tim

Can cisTEM be updated to

Can cisTEM be updated to handle both the RELION 3.0 star format AND the 3.1 format.  

Or maybe a python script to convert the 3.1 format to 3.0 format, if possible?

Hi Darin,

Hi Darin,

we will work on supporting the new format in the next release.  I'm sure conversion is possible, but I don't have a script for it now.

Cheers,

Tim

Thank you very much Tim for

Thank you very much Tim for getting back to me.  

I found in the paper "Estimation of High-Order Aberrations and Anisotopic Magnification from Cryo-EM Dataset in RELION-3.1 by Zivanov, Nakane, and Scheres; "SInce most of the optical properties of a particle are now defined through the optics group to which it belongs, each particle STAR file written out by RELION-3.1 now contains two tables: one listing the optics group and one listing the particles.  The particles table is equivalent to the old one, except that certain optical properties are no longer listed"

Best regards,

Figure out to get a script to support v3.1

Hi Darin,

I have just figure out to write a small program for convention these days. If you need it, should I email it to you?
